So far good.

No one else has posted this so I’m going to save everyone some heartache and let you know this unit will not work properly and do the simple task it claims to do UNLESS AND THIS IS A BIG ONE!!!!…You need to turn the temperature down on the unit to the Temperature you ACTUALLY want like. Between 105-115 degrees not 130-140 like a regular water heater would be set at. The reason for this is the unit is not able to keep up at 130-140 degrees while at the faucet or shower you mix cold water in to compensate. These tankless water heaters are not the “smart” kind like the high end rinnai’s or similar so you have to be smart for it! JUST TURN THE TEMPERATURE DOWN AND IT WILL WORK AMAZING!! Why this is never mentioned in troubleshooting or anywhere I could find online I have no idea but you are welcome, enjoy your hot water!

Good valves ! Gas valves and hook-up are good. Gas tubing under size . It is not 3/4”.

While marketed as 3/4″ PEX-B, the actual diameter of the fittings is too small and poorly toleranced.The fittings look like an awkward hybrid between Type A and Type B PEX standards, but realistically, they don't fit securely or properly onto either one. Standard PEX expansion rings (Type A) or crimp rings (Type B) will not seat correctly, risking leaks or connection failures.

I assumed all connections on these valves were 3/4” based on the description; however, upon receiving I found that the inbound cold and outbound hot connections were 1/2” and I had to use a reducer to utilize these as my pipe is 3/4” throughout.

description is misleading and incorrect. The Shark Bite side of the fittings are for 1/2" pipe not 3/4" pipe.

The Tankless valves are good quality . The only issue was Vevor send out the wrong items those I ordered. I ordered 3/4” fip x 3/4” ptc but I received 3/4”fip x 1/2” ptc. I job was delayed.

The quality of the product is good. Unfortunately I was shipped half inch push to connect fittings not the three-quarter inch that I ordered. This disrupted my project and was a huge inconvenience.
