I’ve never owned a pool until now. We renovated the pool body last year (fall 2014); tested and ran the equipment; and then winterized everything. Since opening this year, we’ve had trouble with the filtration.
First, the pump kept losing prime, so we replaced the check valve and hair basket, which resolved the issue. Now, the filter pressure spikes to over 30 psi within a few hours of operation. Backwashing or even a complete filter cleaning drops the pressure, but then it creeps back up. Typically it runs between 15 and 22 psi. We get a lot of leaves, but I manually skim and clean the baskets daily. The water is currently cloudy, but when operating properly, it's crystal clear.
Aside from the new parts mentioned, we replaced the timer, and added Polaris robot. Everything else is original.
I’ve talked to my pool guys about replacing the DE Nautilus NS-36 filter to a Hayward C4030 cartridge system. But I’m wondering if that will address the problem. Any thoughts on what else might be causing this?
Note that the filter pressure goes up independent of the Polaris.
This is an in-ground, 35,000 gallon pool and spa set up.
Many thanks for any and all advice.
