I'm going to try to hold it together here, but I really want to cry at this point. Our pool started leaking at the end of last season and my husband made no attempt to deal with it then. He wanted to just get through the winter and replace the liner in spring. The pool lost water until it went down to about 2'. You would think it would have been due to a hole in a side wall. We replaced the liner ourselves because I didn't have an extra $700 laying around. The old liner had a gash in the floor about 1". I thought that was going to be the culprit obviously. The new liner looks fab but is still leaking somewhere because we are losing 1" per day. I have a main drain and I personally seated the seals and cut the liner and installed it because I didn't trust my husband. He is not a "measure twice, cut once" kind of guy. He learns from costly mistakes. My hubby puts on the cap with valve and blows air into pipe of the main drain like we were told we have to every fall to close the pool. In an effort to find out if it is the main drain leaking he put in a plug into the drain inside the pool, but we are still losing water and all around the pool is wet, like almost half way around the pool. I have no idea how common it is to have a new liner leak, but we are not convinced this is common and keep thinking it MUST be the main drain. My hubby just headed out to buy a bag of sand to put over the main drain with the plug installed to see if this makes a difference. I am so frustrated right now. We went to the pool store and spoke with the manager who is always very resourceful and he had no clue.
Does anyone on this board have any clue how to troubleshoot this differently or have any ideas or questions? The thought of draining out my expensive water and chemicals and risking the liner shrinking or not lining up is making me sick. Thanks.
