I'll start by saying that I'm a new pool owner so please excuse it if the question is a stupid one . Okay, so we moved to a house that came with a pool in Feb. The pool had been closed for a year or 2 as the previous owners were elder. I was able to open the pool with a few minor issues. At that time I noticed that the main drain pipe was leaking in the connection where it connects to the 3 way - valve by the water pump. I bought a cloth wrap (it hardens after it gets wet) in the pool store to see if it would fix it but it didn't. I tried to remove it but I couldn't because it glued very tight and I was afraid of cutting the flex pipe. So, I didn't pay much attention since the leak was minor (only drops) and left it like that. Now, I'm getting ready to close the pool and during the process of blowing out the lines, I realized the air is leaking through the same main drain connection. So my question is, if water does come into the main drain is there a good change that it will freeze and break the pipe? I'm assuming water will eventually come in since the air I pumped will leak out. But I've read it's very unlikely for water to freeze in main drain because in this area (NJ) water will not freeze if deeper than 2 feet. Does anyone know if I should be concern or if things will be okay? any comments will be appreciated.
ps. The real fix would be to cut the pipe and re-do the piping which I'm hesitant to do because I want to re-do all the equipment piping. The pump and filter are in a small shed and whoever did the the plumbing of the equipment made a web of things which makes it very hard to do any maintenance on the pump or filter.
Note: my pool is 16' x 32'. The deep end is about 8 ' deep and the shallow end is about 3.5 - 4 '. Pool size is about 20k gal.
