CMI Inc - 3/4 Inch IPS Female Threaded Complete Tankless Water Heater Valve Kit with Pressure Relief Valve Water and Gas Connectors - Compatible with Most Tankless Water Heater Brands

After installing the new tankless water heater, the service valves went right on and work exactly as they should. the ease of installation i breezed right through it with no problems, just paying attention to the alignment of handles, and the placement of the pressure relief valve. i couldn't beat the cost-effective purchase. have had the units in for a couple of months or so and no leaks and when i have to service the water softener or any lines they make it really easy

A perfect fit for the Rheem instant hot water unit I installed. Top quality.

I installed a Rinnai on demand hot water heater this past weekend. I have installed a few before and used these types of valve kits. These are great as they provide an easy way to descale the units with built in ports and bypass shutoff valves. These attached with no problems and comes with the pressure relief valve as well. I highly recommend the kit for any on demand installs.

Bought this kit to install on demand tankless hot water heater. All the fittings that were needed came in the kit including gas line and fittings. Only thing missing was a gas valve but that's ok. Everything fit nice and tight with zero leaks of water or gas, and I am a horrible plumber. Usually everything I do plumbing wise leaks. The fittings appeared to be of good quality copper and tight quarter turn valves for flush out. Worked excellent for the water heater install. The pressure guage was, is very cheap and I didn't use it as it did leak and was as tight as I could get it and it just didn't cut it. All in all I was happy.

Fittings were exactly what we needed for our hot water heater. They worked great.

Jink. Too many joints to get everything leak tight and facing the right way. I a gave up and got a more expensive one that doesn't leak. Didn't want to tighten anymore because I was afraid to snap off the water heater's connections. The water connections were the worst. Get one without the threaded bushings. Could never get them leak tight either since they are all thread with nothing to grab onto.

When you buy your heating unit, ...my suggestion is buy a unit with 3/4 nipples in and out,because this valve set-up is 3/4, both ends. If your new unit is 1/2 nipples (like this one in pic) it takes additional fittings to adapt, can be found here also. Otherwise, everything pretty much fell together. I did add a filter/descaler to the intake side.
