We currently have an 18'X40' inground pool, w/ vinyl liner. It currently had 1 skimmer input, and 2 return drains.
The liner in it is in really rough condition (multiple patches, weird stains on it, bleached out in spots, and the entire deep end has a large patch to even keep the water in, with the original liner shrunk down below the water line).
We originally were not sure whether or not we were going to fill in the pool, or keep it, so we've gone this summer with the current liner, and it looks like we'll be keeping the pool.
My question is this, while we are changing the liner, what else should we do to keep things updated?
Some ideas we've had are below:
1) Replace all the underground plumbing to and from the pool. It's currently some sort of steel pipe that ends up shooting bits of rust into the pool. We'd replace this with PVC piping.
2) We're looking at adding a main drain to the pool. From what I've read these seem to be pretty standard in pools this size. Are they worth the extra work to add?
3) Addition of a dedicated vacuum port. After a big storm, we're left with a choice, run the skimmer to clean off the top of the pool, or run the Kreepy Krawly to clean off the floor, would be nice to be able to run both.
4) "Modernize" the shape of the pool. It's currently a standard oval, anyone know how hard it would be to turn this into more of a customized shape that is a bit more exciting?
5) Replace all the hardware such as returns, skimmer inlet, basket, etc.
Is there anything else we should be considering? Anything anyone has recently added to their pool or always have that they consider a "must have" now?
