I have just bought a house with an in-ground fiberglass pool from 1971. The maker is San Juan. I have been keeping up chemistry well and the pool is looking beautiful. But, I am worried about bulging in the deep end of the pool. The walls appear to go out (almost like a pot belly on a human). It is not extreme, but I don't want catastrophic failure unless oil flows out (I'm in Central Texas)
Here is the design that most closely represents my pool: http://www.sanjuanpools.com/pools.ht...Id=38&SJId=450
What do you guys think? I'll try to get a few shots of it later this week.
