My wife and I acquired our 1st pool when we bought our own place. We were assured the 24' diameter above ground pool worked even though it was less than half full and not maintained at all for a couple of years (water was nearly black). Repeated drops in the water level since this spring have made it clear there is a leak somewhere.
A friend who works in pools visited and helped me open the pool so I could recycle the water by connecting some of the plumbing and attaching the vacuum hose directly to the pump. Cleaning and recycling the water was a lot of work including changing the sand but it is crystal clear now. Even since cleaning the water I have been unable to find a cut, tear or hole anywhere in the liner and have been adding water repeatedly for fear the wind would lift and destroy the pool completely if the water drops to any less than 4" at the side.
Thinking that it must be the bottom drain that was leaking my friend finally plugged it before he left and disconnected its hose from the flow valve under the skimmer. Thinking we found the leak I connected more of the plumbing by installing my salt water chlorinator between my filter and return though I have not used it yet. I also changed the old flow valves which were getting brittle. However before filling it up with a truckload of water I found that it still leaks. Another friend suggests that the only economical way to find the leak is to pull back the liner to see where it is wet. Is there another way I can do this myself?
And now even the filter is leaking out the top of the multiport right around the lever. I pulled it apart and it looks fine even the spider gasket seems decent. What can be the cause of this leak and what can be done about it?
