I have somewhat of a dilemma.
This spring I had a contractor install a new liner. After draining as much water as he could he used a shovel and made a trench so all the water and debris would flow out the back of the pool. Before installing he covered back the whole and smooth all the sand and made sure it had a cove all around. (I think thats what its called) Once the pool was filled I saw that that trench did not stay covered up so the liner conform to somewhat like the trench. Very few wrinkles, I did not think it was a big deal.
Yesterday my grandson saw a weed growing in that spot, into the pool the weed had gone through the liner. He pulled the weed and it started to leak really bad. So bad the sand that was around the bottom of the pool got washed away. I was able to go to the outside of the pool and see and touch the liner so I tried to patch from the bottom up. It slowed the leak a lot but did not stop it. so today I got in the pool with googles found the hole patched it and no leak. But now the bottom of the liner is about 3 inches lower then the bottom of the pool wall. When in the pool and put my foot in that spot it feels pretty solid not squishy. I was thinking about putting sand in there as much as I can wet the sand and tamping it then put a sand bag in front of that . I also sprayed weed killer to keep the grass and weeds away from the pool. Is this gonna work or am I trouble. Will I need to put a new liner in. I hope not it costs too much money. Is there something else I can do.
Thanks for all advice given
