TKLS-CK Tankless Water Heater natural propane gas Isolation Valve 3/4" Kit | Compatible Noritz Rheem Rinnai Takagi Navien Service Flushing Valves| Lead-Free Complete Easy to Install Flush Kit

Great kit and really completed my project. The local hardware store as well as the big box hardware stores did not have the gas line I needed in stock or the pressure relief valve for my tankless water heater so without the kit I'd still be without hot water! The flexible gas line made the gas connection quicker and easier. Also the included pressure relief valve saved me from having to go buy it separately. Valves seem to be well made and are leak free so far and fittings feel sturdy and quality made. Time will tell but so far its getting 5 stars from me.

I used this to change from a tank water heater to tankless. It was an AO Smith water heater. Everything worked well to hook up the water and gas connections. I really like the shut offs for the ports to flush it out. It allowed the angling of the valves to provided access later for flushing the water heater while still allowing easy access to the shut off values. I am glad I purchased this to complete the installation rather than trying to get pieces one by one or another kit that did not have all the valves and ports this one did.

Everything I needed to install and feels very durable.

Set up with my rannai tankless water heater. Contained all the fitting I needed with proper maintenance and flush ports which are needed for tankless systems.

Product seems package well. But missing most important parts of the order. I only received 3 hoses. No shut off valve. No air valve. Nothing like the picture. I have to delay my plumber for additional charges since he already showed up to finish the project. I guess it is part of the online ordering experience.

This is the second set of yours that I have installed for friends on new Rheem on demand hot water heaters. I am not a professional plumber/installer so this set makes the install so much easier. I love that everything was included to make it easier.

Buy these hookups if you have no idea what you're doing. Even then, do the research. I feel like you'd save half the money buying your connections from HD

I am an engineer. This is my second order. These are HEAVY cast brass valves and they are beautiful. Some will complain that the handles are tough to turn but this is a good thing , means the ball seals are tight!!! My only "negative" is the water hoses - would prefer flexible hoses as it is easy to crack the metal hoses by bending to fit -- so go slow and it will be ok. Tip for newbies -- also buy the Flow-Aide descaler. Then go to Home Depot and buy a 5-gallon bucket, 2 washing machine hoses, and a $85 submersible pump. Run the descaler through the tankless water heater for 2 hours.
