Bought house about 18 months ago. Just replastered pool, replaced pool light and DE filter. Now I'd like to replumb to install 1) new filter valve (push-pull, not multiport), 2) Jandy neverlube 3 way valve, 3) jandy neverlube 2 way valve, and 4) Compu Pool CPSC-36 salt water chlorine generator. I plan on using 2" pipe and fittings where possible, then i'll reduce back to 1.5 where necessary. On the pump side, there is a pipe from the skimmer and one from the main drain, each 1.5", joined by a "T" and fed into the pump. I'd like to add a 3 way valve instead of the "T". On the filter side, there are two return pipes. One has a brass gate valve (doesnt work well and I cant control high water pressure here so i'd like to put 2 way valve here) and goes to a single "eyeball jet" and I'v been told is likely for a water feature. The other pipe feeds three eyeball returns in the pool.
1) Does the floor have to be level under the filter? Currently it is at an angle and I had to place a small piece of tile under one side try to level it. I can permanently set down a 2' x 2' tile under the filter with thinset and leave it perfectly level if this is advisable.
2) Is it a good idea to use threaded PVC (with teflon tape of course) or PVC Unions in lieu of pvc cement on certain parts to "save" them so that they are reusable. For example, on the filter valve so that if I have to cut the plumbing say between the pump and the filter, the pump has threads and so will the other end, this way I can neatly tie back into the threaded ends without any patches.
3)I understand that there are many ways to plumb it- what would you suggest? keep in mind that i need to install the SWCG after the filter. The SWCG that i bought can be seen in this "how to install" guide. Notice it requires a pipe going up into the inlet and another coming down from the outlet - this isnt like the common straight through "in-line" cells such as hayward. The SWCG transformer will likely be mounted on the wall above the pump or filter as the cord is only abour 6 feet. http://www.inyopools.com/HowToPage/how_ ... rator.aspx
Also, I'm going to relocate the water tap on the wall between the pump/filter. I dont mind moving the filter closer to the pump if necessary to line it up with the water feature return pipe. Should the filter valve be facing the pump instead of the returns?
I lurked around this forum for a while before I joined. I've learned a lot here. thanks!
