I am hoping my liner lasts a while longer yet, but at the time my liner needs to be replaced I am thinking of undertaking some other repairs and was looking for some advice. I have a 16x32 inground grecian pool with about 4' of concrete decking around it. I have two returns and one skimmer along with one port that looks like was dedicated to a suction side cleaner.
1) The concrete decking around my pool is in rough shape and I will probably look at repairing and/or replacing the concrete decking. I guess the coping gets replaced as well at this point. My pool is also not plumb across the length, the shallow end looks like it has settled through the years and there is about a 2" difference between the deep end and the shallow end level. Would it be possible to level this up at this time?
2) The previous owners must have had a leak somewhere in the piping and instead of fixing it they ran new pipe about 1" below grade to the various returns and intakes. The piping they installed is actually 1-1/4. I know because I found one of the pipes when doing some landscaping and had to do a quick repair. I know 1-1/4 seems a little unusual, so I guess I was thinking of doing some replumbing at this point and running new 1-1/2 pipe throughout. Good idea or bad idea?
3) Would it be advisable to add a main drain or is 1 skimmer adequate?
4) I hope to add solar heating in the near future as well, is it best to dedicate a return for the solar or just combine it with the other returns?
5) It feels like the bottom of my pool (under the liner) is just sand? Is that typical? It is soft and seems to be in fairly good shape, but there are some divots, ruts and areas that are quite bumpy. I assume these can be smoothed out before the new liner is installed?
Is there anything else that I should consider when my liner finally decides to give up?
