Misconception #1 – You should always wear rubber gloves when operating a snake style drain cleaning machine to protect yourself from the health risks of sewage. While it is true that plumbers and drain cleaners should always be aware that they and their equipment are potentially in contact with human waste and take appropriate actions, operating a cable style drain cleaning machine wearing only rubber gloves is not one of them. The problem with rubber gloves is that they can become pinched and caught in the rotating coils of a drain cleaning cable, causing great harm to the operator. We always recommend that operators wear heavy-duty two-ply leather gloves or something similar whenever their hands are anywhere near a drain cleaning machine. Thick leather gloves will not get caught between the coils of a snake or cable and can protect your hands from unexpected kinks or loops that sometimes form in the blink of an eye. If you want to wear rubber gloves to take appropriate sanitary precautions against sewage, then wear them under the leather gloves. This strategy gives you two levels of protection!
Misconception #2 — You should put a drain cleaning machine in reverse when retracting cable using a power feed device. Most modern drum style cable drain cleaning machines have a power feed and guide tube. This equipment makes it much easier to feed and retract the cable and serves to protect the operator. Every floor model brand of drain cleaning machine has a power cable feed that allows the operator to easily switch from forward to neutral to reverse while the drum and cable continues to spin in the forward direction. This feature is essential for smooth and effective operation of the machine. If the operator puts the electric motor in reverse and spins the drum and cable in the opposite direction, bad things tend to happen! Most drain cleaning companies coil their drum style cable in a ‘left hand wound’ direction. These cables are simply long, thin springs. Sometimes, like General’s Flexicore Cables, they have a solid inner core, and sometimes they don’t. However, all of them have a ‘direction’ to the outer coil that affects their performance and capabilities when under torque or in motion, and the drums, distributor tubes and power feeds that house and feed these cables are engineered with these capabilities in mind. When you reverse the motor while retracting the cable, you drastically increase the likelihood of kinking, tangling, or weakening the cable. The only time an operator should put the motor and drum of a machine in reverse is when they get a cutter wrapped up in an obstruction, and even then the duration should only be for a few seconds. Save yourself future complications and keep the machine in forward when the power feed is in reverse!
Misconception #3 – Hot water is better than cold water in cleaning drains with a high-pressure water jetter. While it is true that hot water can dissolve grease faster than cold water, the effect at high pressure is marginal. Generally speaking, in real world situations, it is not worth the additional cost and effort. Adding hot water pumps and heating tanks to your jetter protocol makes for a more expensive unit as well as doubling your work at the jobsite. High pressure cold water can do the job almost as fast, without the additional expense and time expenditure. For that reason, in a world where time is money, cold water is the way to go!
Misconception #4– High pressure water drain cleaning jetters with 4000 psi perform better than jetters with 3000 psi. In the past several years, we have seen more and more drain cleaning jetters with 4000 psi come on to the market, claiming that they have more power and effectiveness. However, according to our research, these claims are unfounded. When cleaning a drain, both pressure and flow rate are important factors. The psi, or pounds per square inch is necessary to dislodge foreign material in the pipe like grease and sludge. The jetting process is analogous to spray washing, and a certain amount of pressure, or psi is necessary to scour the inside of the pipe. However, after about 2,500 psi, further increases in pressure fail to deliver significant improvements in cleaning action. From that point on, the gallons per minute flow rate, or gpm grows in importance. For example, increasing a jetter’s flow rate from 4 gpm to 5.5 gpm almost doubles the machine’s drain cleaning speed, regardless of whether the psi is 3000 or 4000. So, look closely at the flow rate of high pressure water jetters before you buy, and don’t be fooled by marketing programs masquerading as science!
Misconception #5 — One of the biggest misconceptions that we hear from first-time General Pipe Cleaners customers is misjudging the ‘initial feel’ of our Flexicore Cable. If the customer is used to another brand of drain cleaner and then purchases a General machine or cable for the first time, they often complain to us that they received a defective cable. To them, compared to the cables that they are used to, it feels limp, weak and not stiff enough to fight its way through tough obstructions down the drain. Although their fears are unfounded, Flexicore does have a looser feel from other cables on the market because of the way it is engineered. However, we reassure our new customers is that the Flexicore will stiffen and strengthen when under torque, giving them clog busting power exactly when they need it the most. According to one customer, “it goes from a noodle to a steel rod in the blink of an eye when you hit the obstruction!” When it comes to General’s patented Flexicore Cable, first impressions can be misleading!

So, as the story goes, a sales rep out west who had spent decades selling a competitor’s plumbing products is hired by General Pipe Cleaners. After initial training, he returned to his territory with a smattering of cables, cutters and drain cleaning machines to get him started.
The first time he demonstrated the Flexicore Cable, he called the company to complain that the pipe snake, “just didn’t feel right!” It felt “limp”, not “springy.”
As Dave Dunbar, National Sales Manager with General Pipe Cleaners explained, “the Flexicore engineering process has the effect of making the cable feel less springy than hollow cables.”
It took a few phone calls to get things straightened out with the rep, but then six months later, he was complaining that the cables lasted so much longer than his former brand’s that he was only selling a fraction of his previous replacement snakes. A small fraction.
It was this story that interested a few of our contractor friends. Why would it be springy? Is it really that stiff and is that a good thing? Would it really last longer?
Knowing General Pipe Cleaners would be at the WWETT Show this past spring, I introduced the General’s team to a few drain cleaning contractors that we are big fans of and have worked with in the past. It was my hope that we could create some valuable and interesting content based on the original story and the contractors having never used Flexicore.
It was soon after the show that we asked for them to send a few of their Flexicore cables to a few of our ProStaff team members to get their thoughts on the cable. They obliged and three drain cleaning pros were sent the cables to use on their existing cable machines, which for transparency, were all competitor drum machines.
As you may know, the Flexicore cable is the result of a process, where instead of coiling a hollow cable, they tightly wrap spring steel around a 49 strand aircraft quality wire rope. This provides the cable additional strength when it is under torque.
Each member of our team received a variety of Flexicore cables based on their typical daily drain cleaning challenges with the request to use them over a couple of months and provide feedback. The team of contractors included Felix Delgadillo, DrainGuys (Chicago), Terence Chan, Impetus Plumbing (Vancouver) and Jeff Keller, Bulldog Contractors (Texas), all are longtime drain cleaning professionals in their area of the country.
As expected, those daily challenges included providing both residential and commercial services, addressing clogged kitchen drains, clogged bathroom drains, clogged outdoor drains, and clogged sewer lines using today’s best technology to unclog lines to keep the water flowing.
While Keller, Chan and Delgadillo confirmed that this was the first time using the cable, Chan stated what all three mentioned, “I’ve never used the product but very excited to see what it can do.”
Chan went on to say, “Initially seeing the product, I was a bit leery how it may hold on to the heads, but it did, really well. In fact, I’ve had trouble with heads from a competitor and the Flexicore held.”
“The screws to hold on the head versus a snap lock is a nice addition,” said Keller.
One of the unique byproducts of the Flexicore process is that the cable stiffens and gets stronger under torque, which Delgadillo agreed, “the cable feels less springy and it does get quite stiff when the operator needs it the most.”
Keller continued, “it caught me off guard and took some getting used to. Most if not all drain cleaners/plumbers are used to listening to their machines and the feel of the strain on the cable to evaluate the blockage, so this was a bit different, but did a solid job.”
As discussed in the WWETT video, when a drain cleaning machine rotates a pipe snake down the drain and it hits a clog or stoppage, tension or torque builds up in the cable. Because of the direction the drum is turning, the reaction of the outer coil of spring steel is that it wants to contract due to the tension. However, because the wire rope is in the way, the only thing that it can do is tighten, which makes it stiffer and stronger and the cable much less likely to kink or break when in use.
Chan concluded, “I would recommend this to peers in the field as it got the job done. I’m curious to see the long-term difference versus some of the cables we typically use and recommend everyone make sure they have the cable sizes they need for their machines.”
We second that Terence! Be sure to size your cables correctly so it all works perfectly.
While the contractors are still using the cables in the field, it was a unanimous decision that more time in the field was needed to truly understand the value of Flexicore cables and how it holds up long term versus other options.
We will continue to check in with the team to provide updates later in the year.
