A tub installed in my house has a drain system in which the plug or stopper is operated by a spring loaded lever mounted through the upper overflow drain.
Problem is that the lever neither stays open nor shut. If you take a shower, water collects because, I think, the drain is partially closed (We have to weigh down the lever with two wet wash cloths to keep the drain open enough to permit the water to drain out). On the other hand, when my wife takes a bath, the water slowly leaks out because the drain won’t fully close.
I think the spring is not strong enough to keep the stopper either open or closed although I don’t understand why that might be. I pulled the whole mechanism out and cleaned off any accumulated hair, etc. Can’t see where it actually sits when in place so I don’t know if there is accumulated s**t clogging the mechanism. Tried snaking the drain and liquid drain cleaners – neither seemed to have any effect.
Any ideas? Can I obtain a replacement spring or mechanism? Do newer tubs develop this problem or is there a new design for the mechanism to avoid this?
