We bought a house with an inground pool with vinyl liner this year. It's been a learning process to understand the chemical balance and care, but I finally got it right. However, the pool is losing water ~1"- 1 1/2" per day. I found leaking (by dye test) around the inlet/return pipe and I want to repair this. What would be the proper sealant to use (caulking or glue?), and any special precautions to take? I noticed the previous sealant is drying and obviously losing the seal, so I think I should remove this as much as possible first before applying new sealant. I asked at the pool store and they didn't have a clue what to use. Just a patch kit, but this won't work because there is no hole! I haven't checked yet, but I also think the sealant between the liner and the steps may be leaking because it is drying and small pieces end up in the pool as we swim. Would there be anything different using sealant there because that will be completely submerged underwater? Thank you in advance.
