Forum Title: Air in hot pipes
I need some more heads on this.. I've recently installed a new gas wh. Have been called back because customer is getting air out of upstairs bathroom pipes when they first turn it one. Wh was installed back in Jan and more then enough water has been ran through pipes so I know that's not it So first time called out checked water temp it was 180 at tap but wh set at 125 so replaced gas control valve and said call back if that don't fix it Customer called back and had same complaint about air still. Went back out and tested temp it was 145 at Tap and 125 set at wh. Ordered another gas control valve from ruud. While there made sure there was not a second wh in home also no recir line anywhere I'm assuming this is not going to fix the issue my question is any thoughts what could be causing this I find it weird I would have 3 faulty control valves
