I had a bit of a mishap while opening the pool this year. While priming the filter, I mistakenly left the return plugs in place. The system wasn't running for long, and I haven’t noticed any drop in the water level, but something still seems off. Specifically, the pool vacuum has very low suction, even when set to high. The pool filters were extremely dirty, so I cleaned them, and afterward, the “low flow” light on the heater turned off, which seemed like a good sign. However, when I attempted to vacuum the pool again today, the suction was still poor. I began cleaning the filters a second time. They're from 2019, so they’re not new but don’t appear to be in terrible shape. While removing them, I noticed a hole that I’m not sure is supposed to be there.

Can you let me know if this hole is expected, and whether the low suction might be related? Hoping that it is just related to poor filters. I have a short video i can share. This is the inside of the filter

I have a Swim Clear 2030 filter. There is a tiny hole drilled into the bottom of the pvc assembly piping (part #cx3030h) within the lower filter body (that connects to pool outlet). Pool repair person says it's supposed to have this tiny hole. What does it do?

I do not know what hole you are referring to. Can you attach a picture of the hole so I can give you a better answer?

thanks. so i feel like typically, if i ran my pump on speed 3 or 4 the heater would turn on. Prior to this commotion yesterday, i saw a similar issue where the heater didnt want to turn on due to low flow. I did suck up a bunch of dirt just opening the pool this past weekend. After rinsing the filters off, the heater did come on at speed 4 (never tried 3), but the flow felt lower than normal (maybe that was just in my head knowing i screwed up opening the pool with the returns capped). But i can put my hand under the vacuum and there is very little to now flow. The pump has a 3 value on it - for skimmer / drains in the pool. I do have some new filters on order and also need to get a new manifold o-ring. I'm hoping that its just bad (dirty) filters and that will resolve the issue.

I would imagine if something in the lines broke, i would have seen water levels decreasing. I haven't seen that. If the lines has a problem prior to the pump, i would suspect air in the pump. I haven't seen that.


EDIT: Update: the new filters seems to have made a world of difference. the pressure gauge is now around or just below 10 and things seem a-ok!. Thanks for all the help
