I’ve had my pool for over 30 years and little to no problems with it, other than cosmetic. Yes, I have replaced the pump and filter tank about 12 years ago. Now redoing plaster, tile, coping, decking, new skimmer, adding auto fill, and dedicated vac line. I took my time selecting and screening a pool contractor for all this work, but have run into some problems (not mentioned in this post), and now have some questions.
Researching your forum, I didn’t realize everything was so complicated. I have a 15-gal pool, no spa or heater, 1hp pump, 300sq ft Hayward filter. I live in Las Vegas.
I am having pavers installed for the decking by a different contractor. He pointed out that the vacuum line PVC installation is questionable in that the 1.5” pvc pipe immediately increases to 2” after it comes through the gunite, has two 90 degree elbows elevating it approximately 6” before the pipe continues to the pump and back down more than 6” on this run of about 30 feet where it joins the skimmer plumbing at a newly installed 3-way Jandy valve at the pump.
He says, I’m no plumber, but it looks like they should have trenched a little deeper and just used one elbow for the turn after it comes through the gunite instead of elevating the line, only to have it slope down on the run in order to go under other plumbing. (He has some concerns using the compactor over this plumbing.) So I did some research and also looked at my neighbor’s plumbing which has 1.5" for vac line going into a 3-way valve before the pump. So now I am very confused. Should they have used 1.5” pvc or is 2” ok? Will it lose pressure as is, with the 2”? From my research, it seems I have more hp and filters than I really need, and that’s not necessarily a good thing? How deep should the plumbing be? The vac line hole was drilled out about 8” below the tile line. The lines have not been backfilled yet. What should they be filled with considering use of the compactor?
I am new at forums but just need some feedback to feel more confident about all this that is going to be buried. Thank you!
