you would think the sharkbite valve fixes it? an update, plugging in the pump seems to fix the issue. however, im not seeing that as a long term fix as I dont desire to pay the gas bill, or void the warranty on my THWH. the condensation drain is not an ideal install either, it sags in the middle. upon lifting the pipe i can hear some runoff into the sump pump. im going to fix the sag so it runs straight down hill, but could this small amount of pooling in the middle of the drain run be really causing this? so my questions:
1. COuld the sagging in the condensation drain line be really causing the root issue?
2. Will isolating the pump per the valve instructions above fix the issue?
3. The pump has an auto feature which through my research is adapts to your needs. Will this still void my warranty and force my gas bill higher?
thanks for all the information and help, great community. SWMBO isnt complaining but im gertting close to being fed up chasing down different leads to the fix.....and calling in a pro
