I am in the midst of a pool remodel, and since I am very new to the world of pool building and maintenance, thought I would pass the plans by everyone and get a few ideas. The pool is a 16'x32' gunite which had a leaking main drain and a single 1/2" copper return. It was terribly neglected, but I am determined to renovate it fully and use it.
Here are some highlights of the plan.
Drilled three 3" drain holes in pool, installed two skimmers. Sealed main drain because there was no way to dig under pool and replace plumbing.
Drilled three 3" feed holes in pool.
Relocated pump and equipment to an area four feet away from pool, now pump, filter, etc is located three feet below the top of the water.
Connected all 3" feeds/returns to 4" ABS pipe. 4" pipe steps down to 2.5" at the pump station to accomodate pump impeller housing.
Pump is a three-phase 56 frame 220v A.O. Smith 3hp motor with a variable speed controller and a network communication card which will allow me to program pump speeds via network. Currently shopping for a wet end that will connect to the A.O. motor. It is my understanding that the three phase motor will both be more efficient and also allow me to have endless control over pump speed, all at about half of the price of a true variable speed single phase pump - anyone else had any experience with this?
Filter is the Hayward DE4820.
Changing over to salt and UV at the recommendation of a knowledgeable friend. Looking for recommendations on a salt generator and UV sterilizer.
The plaster finish is in really bad shape, so I have plans to use SpectraQuartz "F" with an epoxy resin. I wanted to do pebbletec, but my wife hated the feeling on her feet.
I have currently trenched around the pool, set the skimmers and sealed the 3" ABS drain/return rings in the pool and I am getting ready to plumb everything. In reading hydraulics 101, I understand that perhaps it would be better to connect the pool return jets in a large continuous circle, rather than a branch of three returns with a dead-end at the last jet. Essentially the trench is complete around the whole pool, so it would only mean 40 extra feet of 4" pipe, so no big deal. My thinking is that it would equalize pressure to all three jets, is this correct logic?
Thanks in advance, please remember that I am a newbie to pools, but not to plumbing or renovation, so any thoughts are very helpful, and appreciated.
