That's the course of action I decided on today while running errands. I purchased a vinyl patch kit from the pool store and headed home, optimistic. (The store claimed they did not have any liner remnants). However, the patch was a complete failure. A moment after applying it and smoothing it out (it looked and felt perfect) the whole thing became a winkley, bubbly mess. I think I must have applied too much glue. Water began spraying out of the hole worse than ever. (Not sure why THAT happened...). I regretful peeled off the sorry patch and tried again, but it did the same thing. The liner has an awful texture now where all the glue was. I gave up and started draining the pool. Those photos of the blowout were haunting me. The wall looks much darker around where the rust spots are. I'm curious how bad the rust really is under the liner.
How much water do I need to drain out to be able to safely peel back the liner in that area? The holes are about 2.5 feet off the ground in a 4 foot deep (from top of wall) pool.
Also, I was hoping I can use a much larger patch to just completely cover up the area of the liner that is ruined from the glue (about 5"x5", I initially tried to patch two holes with a single patch). Should that work, or should I plan on replacing the entire liner (assuming the rusty wall is salvagable)?
Or maybe I should just try patching again when the hole in the liner is no longer under water. Is there any way to remove all that excess glue that's dried on there?
I dont want my children to get sucked through the pool wall. How dangerous is this amount of rust?
