I have a inground pool that's about 30 years old. When I bought my house the pool was there but was empty, liner torn up very bad and galvanized walls were caving in in some spots. I dug out the spots that were caved in and straightened the walls. A fair amount of the wall panels were rusting through as well. I was able to buy 3' X 8' 16 guage Vinyl covered steel sheets and I used these to screw over the rusted through parts of the walls. I had a guy redo the vermiculate floor and then he put in a new liner, all was good.
Fast forward to this summer. Pool lost all but a few inches in the shallow end over the winter. The liner has shrunk and ripped in spots near the top of the liner and in corners, so, time for a new liner. The problem is that I can see that where the top of the 3' steel sheeting that I relined the original walls with has a gap where it meets the original walls (rusted out sections), which means I'll have to repatch the walls. I've dug down about 2 feet on the one side of the pool to take some of the pressure off the walls so that when I patch the walls again the 2 wall sections will be even.
The thing is that in order to patch the steel walls the liner will have to be out so that I can see what I'm patching. The guy that will replace the liner this time said that the liner has to stay in until they replace the liner because if the liner is removed, it will screw up the vermiculite floor and they'll have to replace the whole pool floor which will cost 1500 dollars.
Also, I want to make sure that all the walls are in good enough condition or can be patched again enough before I have them order a new liner as I don't want to order a new liner only to find out that the walls are too shot to put in a new liner and loose the cost of the liner.
Does anyone have any recommendations on the best way to go about finding out whether the walls are sound enough to replace the liner or whether it's possible to remove the liner without messing up the vermiculite floor so that it has to be redone so that I can check all the walls and patch what needs to be patched?
Thanks in advance for any recommendations,
