I am replacing my pool liner this Spring.
I have removed the old liner and drained out all of the water so I can get in there and take the necessary measurements.
However, groundwater is leaking into my pool through a small crack on the slope from the shallow end to the deep end, and adding maybe an inch or two of water per day (I have a submersible pump hooked up to a hose that I have been using to pump out the water).
I presume that when the old liner was in place that water wasn't leaking into the basin because the water pressure inside the liner was keeping it out.
I have a bad feeling that I already know the answer to this question, but I'll ask it anyway. Do I need to do something to fix this leak before replacing the liner? (Or can I suck the thing dry, put the liner in, fill it with water, and use that to keep the groundwater out?)
I'm assuming that I need to fix the leak in the concrete. So then the next logical question is what do I use to fix it? Water is dribbling out of it at a steady rate, so it isn't like I can just fill it with concrete, right?
Thanks in advance for any suggestions. I tried to find information on this using Google but you can imagine that googling about pool leaks mostly returns people with leaks letting water OUT of the their pools and not IN.
