I'm stumped! I have a slow leak from the drain outlet tube on my '77 Globetrotter. I have disassembled the two drain valves, cleaned the seats and stems, replaced the faucet washers, and reassembled, without resolving the leak. Seats and stems appear perfect, no pitting, cracks, or flaws. There is no leakage from the city water inlet, so I believe the check valve is o.k.
Suggestions about the cause of the problem and fixes would be most appreciated!
I would rebuild all under the vanity, but just getting to the valves is difficult
, and replacing the parts was a real elbow-buster
Finally, I could just let it go, given the leak is 1 oz per hour, but the cycling water pump reminds me I have a leak!
