I am entering my 3rd swimming season with my pool. It was time for a new liner so while the liner was out I did some major enhancements to my pool. I added more patio area, a slide, a pool filter house, and all new plumbing. The skimmer was cracked so I just replaced it since everything was dug up and removed all the 1.5" flex and installed 2" pvc to drain and skimmer and 1.5" to returns and 1" so slide. I have one skimmer and one main drain going to the pump to filter to heater to chlorinator then split to 3 returns and 1 line to the new slide. The slide is about 9' of head more than the next closest return. When using the slide I have to choke down to almost 1/4 the other lines to get enough water to the slide. I was thinking maybe a booster pump to the slide will help this? My question is on a new build the booster has its own line in and out from the pool. I do not have a separate line to feed the booster. If I add inline with the rest of the returns will it cause any trouble with the equipment? I would have the power on a disconnect off my main pump timer so it will not run without the main pump.
