I'm a new pool owner after buying a house with one last fall. This forum has been by far the most useful source of information about pool issues, thanks to everyone who contributes. I opened the pool a few weeks ago and am getting ready to add a SWG. I'd like any advice I can get before installing. I purchased a SwimPure Plus with a T-15 cell. "setup_old" attachment is a picture of the existing pump, etc. setup.
As far as I can tell, I just need to move the input of the booster pump closer to the multiport valve and then make room for the SWG. My current plan (see crude drawing on "setup_new" attachment) is to put a tee just after the output of the multiport valve. Straight through the tee will be a 90 elbow that will connect to the flexible hose for the booster input. The other port of the tee will face upward. From it, i'll run up, over, and down to connect to the existing pipe just above the existing tee for the booster. The SWG (followed by the flow switch) will go in the long downward run of pipe. I'd just cap off the existing tee for the booster.
1. Does that sound reasonable?
2. Any suggestions to make maintenance or future expansion easier (including more extensive plumbing modifications)?
3. What is the purpose of the small black hose connecting the lower part of the return to the higher part after the main pump?
4. Will I mess up the purpose of the small black hose by making the return go higher than any other part of the system (to accommodate the SWG)?
Thanks for considering this, hopefully its a straightforward addition!
(P.S. - if you can tell me anything about my sand filter, I'd appreciate it - I can't make out anything from the peeling labels!)
