No doubt about it, COVID-19 quickly changed the way we work, and play. Travel and in person visits came to a screeching halt. Professional offices, suppliers, even many working shops closed their doors to visitors. Training in the not to distant past was done, for the most part, in person. Conveniently, most trainers adapted quickly to offer online training options. Many of the companies in our industry were already familiar with platforms like Go To meeting. This made the switch to virtual training fairly easy for those trainers.

Some trainers I met through the ESCO group devised hybrid virtual training events. With a few cameras, one that would follow you around a room they kept the hands on training available also.

An instructor in front of a piece of equipment would be led through the troubleshooting in real time, clever and almost like being there.

The question remains, what happens going forward in the training world. In some cases offices that made the change to virtual workspaces plan on staying that way. In some larger cities’ that has created  office space vacancies and those building owners are scrambling to repurpose those spaces to get the rent rolling back in.

In cities like San Francisco it was a tough slog to see more than two engineering firms in a day due to traffic and parking logistics. With online, virtual sessions you can present to their entire staff as well as any locations they have scattered around the world.

I’ve started limited travel myself for training events. I doubt cramming 30 or more folks into a hotel meeting room will ever be attractive anymore. In some cases moving the training into the shop area, parking lot or a large cafeteria  area is a good option to allow attendees to spread out more.

I doubt anyone knows for sure how this will shake out or what “bug” will hit us next that makes  people want to avoid crowded rooms and spaces, but plan on having options. Come up with new ways to engage the attendees. Not being able to see faces, expressions and not getting that in person feedback changes the game for a trainer.  Add polls to your training to get some interaction and a feel for the groups. Consider multiple speakers or trainers to get some back and forth conversation in your online trainings.

The need for having a trained workforce is critical. Equipment is becoming more sophisticated and specific, so factory training will march forward. We would love to hear from all the players in the industry, thoughts suggestions, what we can do to keep you’ all coming back.

Let’s rid the ‘VID and get back to the normal face to face that we all crave.

In recent years, PP-R pipe has become an increasingly popular choice in plumbing and hydronic heating systems. Introduced over 30 years ago, this copolymer made from Polypropylene-Random has been a top choice among plastic piping options. Suitable for both hot and cold pipe, it’s known as a naturally insulating option that allows the installer to make fast connections that are both permanent and leak-free. Using heat fusion technology, the installer can do more than just join two PP-R ends together – they can create a joint that has the same strength as that of the pipe wall. In contrast to other pipe-joining methods, common long-term concerns like corrosion and fatigue damage are eliminated with heat fusion. In fact, fusion connections are touted to be so robust that they will outlast their own piping system.

In the mid 2000’s, a new generation of PP-R pipe was introduced to the market – Polypropylene-Random Crystallinity Temperature – or PP-RCT. Its crystallinity allows the copolymer to resist greater levels of pressure at higher temperatures. The advancement of copolymers in recent years has begun to shift opinions on plastic pipe, leaving behind outdated misconceptions about its dependability.

But the ways of the past are not all gone. Installers may be embracing plastic pipes and fittings, but they have been slower to accept plastic bodied valves. The proven field reliability of brass-bodied construction remains favorable in a time when strong, reliable plastics are still a relatively new concept. As such, manufacturers who work with PP-R and PP-RCT have been trying to figure out how to bridge the gap between the time tested technology and recent innovations.

In order to incorporate brass valves into a PP-R/PP-RCT piping system, installers have historically had few choices. Options for brass valves with fully integrated connections have been somewhat limited. Some piping manufacturers have elected to offer valves that are compatible only with their specific line of piping, so finding a valve that is compatible with all PP-R and PP-RCT piping systems proved increasingly difficult. In absence of a universal solution, installers made use of transitional fittings to connect their brass ends to PP-R/PP-RCT pipe, at the expense of additional leak paths and labor.

That’s where Webstone comes in. Known for their quality brass valves, Webstone has introduced fully integrated PP-R or PP-RCT ends to their most popular engineered products. The Pro-Connect PP-R Pro line now includes the Isolator with Rotating Flange (a uni-flange ball valve with 360 degrees of motion and optional multi-function hose drain), the Pro-Pal Ball Drain, and ball valves (including PP-R/PP-RCT x FIP ends to transition to or from metal piping).

These products all feature socket style connections, which makes the heat fusion process as quick and simple as possible. Valves come in a variety of sizes and are certified lead free for both residential and commercial use. Additionally, all Webstone products carry a lifetime guarantee against manufacturer’s defects – ensuring peace of mind that no other valve manufacturer in the industry can match.
