Results for "flow restriction"

Found out from my wife that our pool filter pressure gauge has been stuck at a weirdly low 6-7 PSI all week and now I can't stop obsessing over it. My 20,000 gallon inground pool has been running fine otherwise, but I'm wondering if this low pressure is something I should be concerned about.

I've heard people talk about high filter pressure being bad, but nobody ever mentions if pressure can be too low. The pump seems to be running, but I'm not sure if the water flow looks as strong as it used to be. Water chemistry has been balanced - chlorine at 2.5 ppm, pH at 7.4, and alkalinity at 110 ppm. Should I be worried about this low pressure reading, and what could be causing it?…more

Around the pool supply store staring at rows of filters with absolutely no idea how to tell if mine actually needs replacing. What should I be looking for to know when my filter is getting too dirty and needs attention?

I've heard something about pressure readings, but honestly I'm not sure what numbers I should be watching for or what other warning signs might tell me it's time to clean or replace the filter media.…more

Every pool season I feel like an idiot asking this, but I genuinely have no idea how many hours my filter should actually be running daily. My kids swim almost every day during summer, and I want to make sure the water stays clean and safe for them. I've heard different opinions - some neighbors say they run theirs 24/7, while others only run it a few hours.

I'm worried about under-filtering and having bacteria or algae grow, but I also don't want to waste electricity if it's not necessary. Our pool gets heavy use with the kids and their friends, plus we've had some really hot weather lately. What's the right balance for daily filter runtime to keep the water properly clean?…more

My pool equipment pad has a waste line that just dumps straight out to the side yard with zero control — no valve, nothing. I found a YouTube tutorial on how to splice in a shutoff valve, grabbed the supplies, and cut into the pipe... and now I've got a bigger mess than before. The dry-fit didn't hold the way the video showed, one of my cuts came out slightly angled, and I'm second-guessing the whole thing before I actually glue anything permanently.

The waste line is 1½-inch PVC coming off the back of my multiport filter valve. It dribbles between backwash cycles because there's nothing shutting it off, and I'd like to fix that properly. I want to understand what type of valve to actually use here, how to prep the pipe ends correctly after a rough cut, and how to solvent-weld everything so it doesn't leak or blow apart under pressure.

Can someone walk me through the real process — choosing the right valve, making clean cuts, dry-fitting, priming and cementing, and how long I need to wait before firing the pump back up? I want to get this right the second time.…more

During pool season, is it dangerous that I'm getting conflicting advice about using DE powder with my cartridge filters when I've got kids swimming daily? My pool store said it might help with clarity, but I'm reading mixed reviews online. I've been cleaning my cartridges regularly and they seem fine, but my water isn't crystal clear like I want it. Some people swear by adding DE to cartridge systems while others say it's pointless or even harmful. What's the real story here? Will DE actually help my filtration or am I just wasting money and potentially creating problems?…more
