“Good product after I returned the 1st one when it failed 2 days after install and left me with no heat for the second time in a week. No hassle return and the second one is all good so far.”
“Don't know why, but both type L and type M tubing was 'loose' in the ports. I took the valve apart to solder it because of the heat required to heat the thick brass. I as able to a tight seal even though the pipe wasn't snug in the port as it should have been. Tip - use a small C clamp to hold the valve in place when you screw the plate back on after soldering, it's much easier to compress the spring that way. Besides that issue, value works flawlessly.”
