Hourleey 3/4 Inch IPS Isolator Tankless Water Heater Service Valve Kit, with Pressure Relief Valve, Clean Brass

These devices are absolutely essential for tankless water heater applications. They greatly help facilitate the necessary servicing that "Should" be done to them. It also provides an integrated and reliable means to shutoff and isolate the "hot and cold" lines at the water heater, so that the water can continue to be used throughout the house without the worry of back-flushing the hot waterline, through a mixer valve commonly found within modern faucets, and flooding the house in the event that the heater has to be removed for servicing. This particular valve is made to a very high standard of quality, and will likely last for a very long time without fail. I would place it on the same level of quality (if not higher) as some of the more expensive household name brands available at the big box stores. The kit comes with a union, on each valve, that utilizes a flat rubber gasket for sealing. nothing about this appears to be proprietary or hard to obtain in the event that they might need to be replaced. I have installed many of these throughout the years, and will now always keep one of these on my shelf ready to be installed. I am very happy with this item.

Was a bit concerned having read a few negative reviews, but gave it a shot since most are positive and Amazon is easy to deal with in case I'd have to return. Some reviewers complained about leaking. I did have one of the threads drip a little under pressure, but tightening it up solved the problem. Just make sure you're using thread seal tape where needed, tighten everything well and you'll be fine. There's also no need to over tighten. Functionally, all the valves felt good, nothing about the kit felt flimsy or cheap. Amazon delivers quickly, what else can you ask for? Would recommend for professionals or advanced DIYers.

Quality valves - good value for the money. The ONLY complaint I had is the advertising pictures. The hot (red) valve I received has the over-pressure port 180 degrees out from the main water cutoff. There was not enough clearance between the wall to install the overpressure valve while keeping the main valves aligned. By twisting the valve orientations, it worked - but it looks ugly. I wish I had paid closer attention to the porting alignment of this valve set. Other than this, the valve works great and is of good quality.

Easy to install and I think it's a must for tankless outdoor units
