Low point drain is stuck
Our 2013 Thor A.C.E. 29.2 has 2 low point drains, one on the input side of the water pump, the other in the output side. The output side drain refuse to pop up regardless of the effort. Last winter, I chose not to deal with it as I reasoned that pumping antifreeze through the system would displace any residual water. I know that replacing the little pop up valve is the ultimate resolution but it’s hard enough to reach just to get a hand on tucked away behind the WP. I’ve sprayed a little PB Blaster on the thing but worry about degrading the nylon or plastic. Thoughts? Suggestion?
