House construction

These are very nicely made pieces of plumbing equipment. They have a couple features(that I’m not sure are unique to this set) that at first seam mundane then prove very useful. First, is how they attach to the unit. It’s a union fitting where you first attach an adapter to the inlet/outlet of the heater, then when you’ve got the rest of your plumbing lined up, you join the union fitting at the top of the valves to the tank. If this feature did not exist, you’d have to spend another $20 on unions to plumb it correctly. Second, is the fact that the service side of the valves are separately gated. On some cheaper models, turning the service handles(the yellow ones) would close the inlet/outlet and open the service ports. Well, that works well enough, but what if I want to fill a bucket with hot water right from the heater, or connect a hose to the cold water inlet? With these valves it’s easy. When the valves are in their normal “on” position, you can simply use them like a hot/cold water hose bib. Quality wise they seem great. Though a bit pricey at $75, you get what you pay for and I’m really happy I didn’t cheap out and plumb my new heater without them.

***My Rating Definitions***
5 Stars: Works exactly as advertised, fit/finish are what you’d expect when purchasing this type of product AND it is a good value
4 Stars: Works exactly as advertised, fit/finish are what you’d expect when purchasing this type of product, might have a minor flaw
3 Stars: Generally works but I’d change a few things
2 Stars: Barely works but can be made useful if you try
1 Star: Useless, does not perform it’s intended function whatsoever and is generally a waste of money

We’ve had our tankless hot water heater for 4 years and after poor performance we found out we had not descaled it, ever. When it was installed the plumber failed to mention how to maintain it and did not leave a single instruction booklet behind. We contacted the manufacturer and they sent us instructions for descaling. We became confused when we could not seem to find the clean out valves. Turns out none were ever installed. We had to dismantle all the plumbing to the unit. It was a nightmare but we did not have the valves to put in at that time. As soon as I could I ordered these.

The valves arrived packaged neatly. There were clear instructions on the installation and we actually did it ourselves with little plumbing experience. The valves work perfectly. I am so happy that I can clean out the heater with just a twist of knobs. Everyone who has a tankless heater needs these.
