Great part but
This is not a review on the part which is great. In general my advice would be not to use tape for water sealant. Not as good as regular sealant & once you get all the parts together it is almost impossible to go back & fix leaks.

Works great
Im using in a large RV, replacing a very small tank water heater, this product is fabulous.

Don't expect to be able to hook a water hose up to the valve
Product arrived on time with no damage. They seller also included a water pressure gauge as a complimentary gift. Installation was simple and had no issues. The only reason I am giving a one star on ease of use is the fact you cannot hook a water hose up to the valve to clean your tankless water heater as it will not seal and leaks. I am now looking to take the one valve apart I did not use to see if I can adapt a shutoff that will work for hooking up my tankless cleaning system up to it. If you don't care for this not working as it should and need a quick replacement it fits the bill.

Fitting leaks
The fittings donโt tighten up on the top of the tee ! They only go about 2-3 treads and they leak

valves are good but...
I installed this kit a few days ago and "most" of it works well. There were some 1/2 inch to 3/4 inch adapters that came with the kit that leaked like a sieve when installed. I replaced those parts with some from a local hardware store and now it seems to work fine with no leaks.
