I'm replacing my skimmer and pipes in my 30 year old In-Ground vinyl pool (doing it myself). The skimmer is a Hayward SP-1084. Three questions about it:
1) To replace the skimmer, I know I drop the water line, disconnect the pipe, and remove the 12 or so screws from the faceplate. Remove the old unit, pop the new one in and put the screws back in. Is there anything else though? Like maybe adding a caulking/sealant or something around the edges? Anything else?
2) You know how you surround the pipes with sand in the ground so that rocks don't damage them? Well, do I do that with the skimmer as well? I'd say I should just to be on the safe side, but the problem is that sand won't be a good base for the stone pavers I'm installing. What do people do here? Surround the skimmer with sand and or no sand? If sand, how do they handle the fact that there's no base? Maybe just a 2" layer of sand surrounding it or something?
3) Should I replace the pipe connections on the wall of the pool while I'm here too? Do they ever wear out? I'd prefer not to if there's no reason to since the liner is attached to it and I wouldn't want the liner to get out of alignment plus sometimes it's best with the whole "If ain't broke don't fix it". But if the gaskets wear out on them or something I will. As of now I don't have any leakage that I'm aware of with them.
