I have a 18X36 in-ground pool. Just had a new liner put in - but had the problem before that. I seem to be losing water down to the level of the skimmer - but only when I have the pump running. If the pump is off - no water loss. is it possible that my multi port valve has a blown gasket thus allowing the water to leak past to my backwash setting?
