In homes, small businesses, and large industrial settings, plumbing systems and drains need cleaning. In many of these settings drain cleaning consists of pouring chemicals down the pipes every few years. In other places and businesses, drain cleaning is a much more substantial job.

Restaurants and food businesses put undue stress on their drain systems with all of the grease and food waste they discard every day, requiring heavy-duty industrial drain cleaning equipment to remove troublesome blockages.

In older homes or businesses that are located next to old trees and their root systems, the situation is similar, as tree roots can infiltrate drains and pipes, clogging them severely.

When blockages like tree roots or a longtime build-up of grease come into play, chemical solutions do no more than tickle blockages. This is why there are a wide variety of industrial drain cleaning devices on the market today—there is a need for machines that can clean severely blocked drains quickly, cheaply, and efficiently.

Types of Drain Cleaning Machines

Industrial strength drain cleaning machines can be divided into roughly three types: hydro-jetting machines, drain snakes, and power rodding machines.

Hydro-jetting is the process of using a high-pressured flow of water to scour the interior surfaces of the plumbing pipes. This removes scale, grease and other debris that has built up inside the pipe walls over time. Drain cleaning machines using this method work in more or less the same basic way.

First, the operator inserts a hose that’s connected to a tank of water into the clogged pipe. The hose can withstand the high-pressured water that’s sent into the pipes, and a specialized machine pressurizes water from the tank. This hose then delivers a high-pressure jet of water into the pipe, the pressure of which varies depending on the condition of the pipes. In general, machines may pressurize the water up to a 5,000 psi or more and deliver as many as 20 gallons of water per minute. The process of removing the blockages from the pipe involves working with gravity. This type of machine can be quite effective at drain cleaning, but it does have downsides, including freezing in cold temperatures and the various dangers that can come along with using high pressure.

Perhaps the most common kind of drain cleaning machine is called a drain snake. Drain snaking has a simple operation that is often effective, especially for home plumbing use. Industrial strength drain snakes are, more or less, a long spring cable with corkscrew on the end, attached to a motor. The cable is inserted into the clogged pipe, and the motor feeds the cable into the pipe. With luck the cable or corkscrew at the end snags any blockages in the pipe and can then be pulled out with the blockages. This kind of drain cleaning machine is common, but it is often not suitable for more challenging drain cleaning applications.

The last of the three most common drain cleaning machines work via a method known as “power-rodding.” Developed as an alternative to drain snake machines, power rodding systems use a flexible metal cable that threads into drain systems and around bends and joints. A cleaning head with very sharp teeth is installed at the leading end of the cable. This cleaning attachment is sized to the diameter of the pipe being treated. An electric motor rotates the cable, causing the sharp cleaning head to turn at a high rate of speed. This action obliterates the obstruction blocking the pipe, shears off any protrusions such as tree roots and shaves away years of sludge buildup. The high-speed cutting tool shreds the obstructive material blocking the pipe into small fragments that are easily flushed away when the flow of water is introduced into the pipe.

While all three of these methods are viable depending on the application, all three have downsides and issues. However, one technology – flexible shafts—when applied to drain cleaning machines, can help to rectify many of these issues, and serve as a complement to other drain cleaning machines.

Flexible Shafts in Drain Cleaning

A flexible shaft is a precisely defined and configured nested group of springs, tightly wound so that it has torsional or rotational strength, as opposed to the tensile strength found in standard wire rope or cable to which flexible shafts bear a resemblance.

What makes flexible shafts specifically useful is that flexible shafts can bend, but also still rotate. In other words, a flexible shaft transmits rotary motion much like a solid shaft, but it can be routed over, under, and around obstacles that would make using a solid shaft impractical.

Flexible shafts are used in a number of applications, including advanced aerospace technologies. Their flexibility, combined with tensile strength, makes flexible shafts a force in the tight, twisted environments often encountered in drain cleaning.

When compared to other drain cleaning technologies, drain cleaning machines using flexible shafts are advantageous in that they are smaller, lighter and more flexible; easier to clean; and enable the use of a camera in drain cleaning.

Flexible shafts are as strong as other kinds of cables used in drain cleaning, but they are smaller and lighter, as well as more flexible. These characteristics are helpful in two ways. First, flexible shafts’ low weight and size is useful primarily for the operators of drain cleaning machines in using and transporting the equipment to the job site. The cables traditionally used in drain cleaning can be large and heavy, as well as difficult to transport. In addition, traditional drain cleaning cables, which more or less resemble extremely long, tightly wound open springs, are not very flexible. This can make maneuvering the cables through drains difficult. Flexible shafts are notably more flexible, so they can be useful in drain cleaning applications in which the clogged pipes are particularly bendy or hard to navigate with the stiffer traditional drain cleaning cables.

Another advantage flexible shafts have over traditional drain cleaning cables is that they are exceedingly easy to clean. Traditional drain cleaning cables are like large hollow springs—springs are by nature open to the air, so in drain cleaning, as the cable moves through the dirty drain, unclogging debris, it is likely for that debris to become lodged in and on the cable. Being that these cables are long and tightly wound, it is a hassle for drain cleaners to maintain them and keep them clean. Flexible shafts, on the other hand, are covered in a protective casing, making clean-up after a drain is cleaned much easier.

Lastly, flexible shafts can be advantageous to use over other drain cleaning methods in certain situations because they clean drains without water, which enables the use of a camera. When hydro-jetting, camera use is impossible due to the high volume of pressurized water used. Cleaning a drain using a machine based around a flexible shaft (or other dry cable) allows a camera to be fed into the drain just behind the spinning end of the cable. This can be helpful as it allows drain cleaners to see what exactly is blocking the pipe, enabling them to adjust their cleaning method if need be.

One notable example of flexible shafts being used in drain cleaning to great effect is their use by Clog Squad, a Michigan-based drain cleaning contractor. According to Clog Squad, it had been searching for a lighter, safer and easier way to clean drains, and found it in the flexible shaft.

The Clog Squad’s Clog Dog drain cleaning machine is based around the use of a flexible shaft to clean drains, and according to Clog Squad, the use of flexible shafts with the Clog Dog has made the job cleaner, safer, and way more effective.

Clog Squad gets its flexible shafts from S.S. White, one of only three flexible shaft manufacturers in the United States. S.S. White has helped Clog Squad cleaning by ensuring that its flexible shafts are always designed to exact specifications using proprietary software.

Overall, all of the three main methods to industrial drain cleaning have a place in various applications. It is clear that flexible shafts are a light, powerful, clean, and effective new method to clean drains that can serve as an excellent option in all kinds of industrial drain cleaning applications.

According to a Kabbage survey of construction firms, 28 percent cited cash flow as the biggest challenge during their first year in business, outweighing finding new customers. As your business grows, the struggle to manage a positive cash flow may continue.

Towards the end of a project subcontractor fees, invoices, inspection fees and finish materials are due all at once. If you front-load payments or don’t track outstanding bills, you may find yourself undercapitalized.

The good news is that there are practical steps you can take to structure your cash flow and stay ahead.

Align project cash flow with company cash flow.

Plan to pay your company’s quarterly taxes, marketing costs, insurance premiums and other predictable expenses when big bills for your project are not due. Additionally, if you invested in capital equipment, you may be able to claim depreciation and other write-offs to minimize quarterly tax payments and free up cash.

You can also work with your accountant or use tools to analyze your finances and make small adjustments to smooth out the peaks and valleys in your cash flow.

Break up your invoices.

Customers appreciate prompt, smaller bills because it helps them manage their own cash flow. John Montijo took several years of trial and error after starting his construction business in Staten Island, New York to figure out the best way to ease the burden on his business and his customers.

John realized that he didn’t have to follow the industry standard of billing in three or four large installments over the course of a job. Instead, he broke his invoices up further, billing after each stage of a job: for demolition, sheetrocking, windows, insulation, plumbing, electrical work and so on.

Instead of writing a check for $25,000 on a $100,000 job, John’s customers can pay $10,000 at a time, a cash flow win-win for both sides.

Have a cushion.

Dennis Moloney of Best Restorations in Delray, Florida, doesn’t like when his company’s cash flow gets tight.

This forces him to devise new budgeting strategies to stay ahead. Dennis takes advantage of early-payment discounts from his vendors to save money and utilizes lines of credit to bridge cash-flow gaps.

“In 14 years, I’ve never bounced a check or been overdrawn, and I want to keep it that way,” says Dennis. “I borrow to make sure I’m always looking good. “

As the HVAC industry evolves further in response to new market opportunities, sustainability initiatives and changing consumer demands it’s easy to be left at a loss of how to cut through the marketing speak and deliver benefit-driven information to your customers. Putting in the extra work to fully understand how to translate product features into real-world customer benefits will give you an edge in the market. Below is a discussion on how to navigate an industry of new and old considerations across customer demographics. Follow along to understand how you can shift your strategies to build customer relationships through simple communication training of your sales staff.

Define your competitive edge through no-nonsense delivery

Is it just me, or does every HVAC product on the market have the same features?

Tell me if you’ve heard this one before: “Our new, highly-efficient product provides homeowners with a simple, flexible, and cost-competitive solution.”

Does this sound like a product line you offer? Truth be told, this description could apply to any number of products. For example, a system that offers “zoning” could be anything from a sophisticated ductless system to a simple air conditioner with manual air dampers.

Here’s the problem: today’s customers are the most educated customer base we’ve ever experienced. With access to information at our literal fingertips in our smartphones, customers can fact-check a sales pitch in an instant. HVAC repair and replacement is an expensive investment for most customers to begin with, so it’s understood that they want to know exactly what they’re paying for.

If you state that a product is efficient, customers want to know:  How efficient and what are the benefits? Compared to what? Does it cost more, if so, what’s the price difference? Do I really need it?

If you’re not being clear with your customers, you can trust that they are getting their information elsewhere — perhaps even pulling purchase decision information from your competition.

There are simple improvements to your sales information delivery that can help to move past the jargon and build meaningful conversations with your customers that leave them feeling well-informed and satisfied in their decision. In short, you can build credibility – and become the authority –  by being honest and transparent.

As mentioned, using vague terms to describe a product as efficient, variable, or flexible tells the customer very little. The way to fix this is to always speak in terms of comparison. By speaking in comparisons, you will educate the customer on all of the options available to them – not just the one you’d like to sell. This is a critical step in achieving value in customer satisfaction.

If you’re not comfortable speaking in comparison, here are three ways to help get you started:

1. Stop talking features & benefits and start talking sell points and personas

If you’re speaking to a customer about a solution they are just one step away in the sales funnel from making a purchase. It’s important at this stage that you carefully consider what you say and how you say it.

Consider this: most brochures you’ll hand a customer have a long list of features & benefits… those features are often phrased in comparison to an older version of that same product or directly to a competitor’s product – “Even quieter!” or “More flexible than ever!”

But the homeowner doesn’t care if it’s “even quieter” than a previous generation of a product that isn’t in the consideration set they are making for their home. Focus on the information your homeowner actually wants and needs: what options do you recommend; what specifically makes you recommend these based on my needs; how much does it cost?

Hone in on information by defining the sell points for all the products in your portfolio. An easy way to do this is to determine the five whys for each of your products:

• Who would most want or need to purchase this product?
• What type of situation is this product most suitable for?
• Why would they need this product?
• When can we promise to deliver this product to the customer?
• Where are most of the customers geographically located who need this product?

Notice the emphasis on the extremes in these questions. The goal is not to answer in general – “who could use or purchase this product” – but rather “who MOST wants or needs this product and why.” This is critical to defining the true selling points of a product.

By taking this approach, your team will be able clearly to describe the important reasons behind a recommendation because they have clear guidance as to why to recommend it in the first place. You might even consider building a questionnaire that will help both you and your customer come to a decision on the right choice for them.

2. Group your product offerings using tiers

Instead of confusing customers with an onslaught of product brochures covered in brand names, shiny logos, and pretty pictures, consider packaging your products into tiers. Most homeowners are able to easily pick up the concept of Good, Better, and Best – or Bronze, Silver, and Gold.

By grouping your offering into rungs on a ladder, you’re giving the customer a baseline to compare products against one another. The key to this approach is to ensure your groupings offer key differences. Perhaps package A is best for the cost-conservative homeowner, package B is best for the energy-conscious customer, while package C is most suitable to the customer seeking a quick turnaround.

With this system, customers can easily determine the difference between your products and make informed decisions on which products best fit their needs.

3. Give three options whenever possible

When ordering drinks at your local coffee shop, why is it so many of us opt for the medium size? A small seems too small, and a large seems, well…too large. When we are given three options, often we are seeking the Goldilocks “just right” feeling.

No one wants to miss out on an upsell, but the goal should not be to dupe your customer into buying the highest-margin product by failing to tell them about a more cost-effective option that likely checks off the needs on their list.  Provide customers with three options: something that doesn’t quite meet their needs, something that over-delivers, and a solution that falls in the middle.  Because you have tuned in to exactly what the customer needs, selling the middle option in comparison to the other two should be simple.

If you are the service provider for all three options, this strategy gives you an added bonus. If the customer chooses the more elaborate option, you’ve earned more. If they choose the less desirable option, they will know up front what they’re getting and perhaps sacrificing – and you’ve earned their trust in the process.

What does this sound like?

The common – although tired – sales pitch I shared at the beginning turns into a richer conversation once you’ve added comparisons.  In this example, I’ve uncovered that the customer is most concerned with the ability to stay comfortable in their home, with affordability being their second concern.

“The package I’d like to offer you today is our Premier package. Your upstairs and downstairs will have individual thermostats, which I know is what you were looking for. I’d like to share with you some other options for your consideration. Our Platinum package would give you even more comfort options: every room could have its own set point. The higher price could be offset with some rebates, but it is more expensive than the Premier package. Another option is our Economy package. This is the most affordable of the three, but it doesn’t come with the zoning you asked for. Given what we have discussed so far, I think the Premier package most meets your needs.”

By defining the sell points for your products, grouping them into tiers, and offering at least three options you can successfully provide the customer with a well-thought-out and easily understandable reasoning for your recommendation.

Resolve to make comparison-speak a habit in your organization and your customers will see you as a more trustworthy source of information for their buying decision process.

Residential plumbing and HVAC installers take note: you can pipe an entire home with the durability, flexibility and cost-effectiveness of PEX — for plumbing, fire sprinkler systems and radiant floor heating.

Here’s how…

PEX plumbing

With more new homes plumbed with PEX than copper and CPVC combined, you’re probably already aware of the benefits of plumbing with PEX. However, you may not know about a newer, smarter way to install a PEX plumbing system that goes in faster, uses less materials, requires fewer connections and minimizes your liability.

This innovative design is called Logic plumbing.

The Logic approach uses the flexibility of PEX pipe to minimize connections and reduce potential leak points while also incorporating multiport tees located near fixture groupings to limit the amount of pipe and connections needed.

What’s a multiport tee, you ask? It’s essentially a bunch of tees all molded together to create one long tee with multiple outlets. This design greatly reduces the number of fittings and connections needed to plumb a home (think: reduced materials cost and labor time).

Here’s an example of how a multiport tee saves installation time and materials: a flow-through multiport tee with six outlets has eight connections (six connections for the ports, a main flow-through inlet and a main flow-through outlet). Six regular tees, on the other hand, have a whopping 18 connections. That’s an increase of more than double the connections — and double the installation time.

Best of all, multiport tees are not considered manifolds, so they can be installed behind walls without the need for an access panel. Double win, there!

For a Logic layout, a main line connects to a multiport tee with distribution lines going out from the multiport to provide water to all fixtures in a single or adjacent grouping. This design uses significantly less pipe than a home-run layout, with just a few more connections. Plus, it requires considerably fewer connections compared to a trunk-and-branch installation.

For example, a 2,300-square-foot, two-story home using a Logic design requires only 637 feet of pipe while a home-run system uses 1,515 feet of pipe. And, while it’s true a Logic installation uses slightly more connections than a home-run layout (59 vs. 48 in the 2,300-square-foot, two-story home example), the amount of pipe savings is significantly more beneficial with the labor and material savings you get with less pipe to install.

A Logic layout also installs much faster compared to a trunk-and-branch system due to the vast reduction in connections. With the two-story home example, a Logic layout uses a mere 16 fittings and 59 connections compared to a whopping 96 fittings and 165 connections for trunk and branch.

PEX multipurpose fire sprinkler systems

If you’re a licensed plumber who wants to add an additional service to your offering, check out PEX multipurpose fire sprinkler systems. These systems combine the fire sprinklers with a home’s cold-water plumbing. It’s genius!

Installation is remarkably easy — the sprinkler is essentially just another fixture to tie into the plumbing line. For most contractors who already install PEX plumbing systems and have the tools, knowledge and, most importantly, the relationships with the home builders, this is a slam dunk.

Depending on the jurisdiction, multipurpose systems typically don’t need check valves or backflow preventers, and because they combine with the potable plumbing, they don’t use antifreeze, so all those added costs are eliminated.

To get started in most jurisdictions, licensed plumbers just need the appropriate training and a quality design that meets the NFPA 13D standard requirements for home fire sprinkler systems.

PEX hydronic radiant floor heating

There’s nothing like the comfort of radiant floor heating — ask anyone who has experienced it. And, homeowners will pay nicely for a quality radiant floor heating system, so there is definitely income potential if you can learn to do it right.

That said, with radiant floor heating, there’s a little more to learn. But, like fire sprinkler systems, starting with a proper design is key. If your design is wrong in the beginning, there’s not much you can do to fix the system once it’s installed.

Take advantage of the radiant design services many PEX manufacturers offer to guide you through the process. There are several design factors to know, including floor R-values, heat-loss calculations, pipe sizing, loop lengths, pump sizing, manifold types and more.

Once you learn the basics of radiant design and get a few small jobs under your belt, you have the potential to take your expertise to the next level with bigger, more profitable projects. But again, be sure to get the proper design and training before you tackle a radiant project. It will be well worth it in the long run.
