Last October, we bought a home with an existing AGP. This is my first experience with a pool, and it has been a real PITA at times. (Had not heard about TFP until a couple of weeks ago when a friend brought it up.) I've had some fun adventures with this thing, just like every other newbie, only my adventures have been much worse than anything experienced by anyone else since the beginning of time (again, just like every other newbie. )
I just replaced the liner since I've been fighting a leak since July. I'm assuming that the leak was caused by the steps moving around on the liner. Originally, the steps were only mounted to the deck on one side (since there was only one handrail.) The kids love to hang on the steps and swing around, so even with 100 lbs of sand in the bottom step, they were constantly moving. I finally added a handrail to the other side. It looks a little strange, since the handrails don't match, but at least the steps don't move around anymore.
The pool guys (and people on this board) recommend putting something under the steps to protect the liner. Since I have the old liner laying around, does it make sense to cut a portion of that liner to lay under the steps? It wouldn't add any padding, but at least the steps wouldn't be sitting on the actual liner? Would that be enough to protect the new liner, or do I need to go with a "plumber's mat" or something and if so, about what will it cost?
