My first post and I hope I am posting in the tight section. I have an~ 13,000 inground pool. DE filter, intelliflo 4 speed pump, intellichlor, SWG with bubbler, weeping waterfall and spillway from spa. I have a question about the returns in my pool. I have 5 returns. When my pool is running at 2200 only 2 of the returns work with a nice strong flow and another one just barely comes out. When my booster pump is on I have really good flow out from 3 returns and barely anything out of the other two. However water does come out of the bubbler valve when bubbler is turned off (just a stream of water) at 2200. I just "assumed" that at normal run at 2200 and even when my cleaner is on for 2 hrs at 2500 (same returns at 2200) that ALL 5 returns would be working. Can someone tell me what is "normal". I do not run my booster pump on a long, reg. basis. Maybe an hour a day. Thanks so much!
