Hi everyone. I'm new to the forum and also a newbie pool owner so please excuse me if I don't use the right terminology.
We had some really cold temps here in Canada and the 3-way selector that joins the skimmer drain and bottom drain hose to the pump has cracked one night and I woke up the next morning to find the pool almost empty. I quickly lifted the hoses above water level to prevent further draining but i was reluctant to try refilling the pool because of the cold. So i left it with only about 10 inches of water for a couple weeks until temps went above freezing for a day or so and I was able to fill the pool about half way up.
Now a few days later I noticed a bulge in one of the sidewalls, above the water level. See attached pic. I tried pushing it back out but was not able to. I can't put anymore water in the pool at this time as temperatures are well below freezing again. It doesn't look like there's any damage.
my questions are: is this something that will fix itself when I fill the pool all the way up or do I need to repar it? And if I need to repair it, how do I do it myself? is there like a tool i can use to bend it back or do i need to remove and replace that panel?
