Talk about brain-fart. Holy crap.
First some background, up here the municipal wate is only 60 psi at most. So we don't need PRV's on the supply line.
I installed a Grundfos MQ3-35 in 2 different houses that are both on cisterns. I also installed 2-50 gallon Bradford-white water heaters in both houses.
Fast forward 4 months, I have 1 tank that the T&P is drippping. Cycled the T&P a couple times but it leaked even more. The water that is feeding the cistern is very dirty so I figured the dirt was causing the T&P to fail to seat. I replaced the T&P 2 months ago and have not had any more problems.
I get called today to the second house for 2 dripping T&P valves. They are not dripping at this time but show evidence that they have recently.
Told HO to watch the tanks and call me as soon as they start leaking again.
So here I am, at home having supper, and it hits me. The damn pumps have an internal check valve!!!!
Going to install expansion tanks early next week.
Like I said, brain fart!!!
