So I already have small leaks in my pump and sand filter. Already planned on replacing the pump, sand in the sand filter, the sand filter cap, and all hoses. However over the last few weeks I've noticed my water levels drop quickly. Normally this is a sign of a hole in my hose, but they look ok. I did an inspection around the out side of the pool and found a puddle on the outside of the pool in one area. I put on a set of my sons goggles and inspected the liner all around that area especially since I have a black lab that loves to swim (she is never allowed in alone and normally stays away from the sides and obviously never touches the bottom), but see no signs of a hole. Does anyone have any recommendations for locating where its leaking from?
