Fixing an Air Leak on the Pool Filter
Greetings again, fellow pool care warriors! It’s been a while since my last post, but like they say, “No news is good news!” Our pool’s looked perfect for over a month now. I was very curious about what the pool place would say when I delivered my water sample today, since I’d been slacking on regular liquid chlorine shocks and brushings and the other usual pool care maintenance.
I learned that my pool did contain some chlorine, but it was at 1.5 ppm, which is just below the recommended 2.0 - 4.0 ppm. The reason for this was that my stabilizer level was still rather high. They only prescribed a 1.5 gallon liquid chlorine shock, along with 18 pounds of Calcium to boost the hardness of the water.
I was glad to remember, while I was in the store, to mention to Ken, the friendly guy who helps me each time, that I’d been noticing a lot of gurgling sounds and tiny bubbles (in the wine) coming from one of my circulation jets. I suspected an air-leak, but didn’t consider that its location was at the top of my cartridge filter. Never having really noticed that the backside of my filter was wet most of the time, I told Ken about this and he said that it’s there that the air was creeping into my system.
I purchased a new O-Ring, made by Hayward, my filter’s manufacturer. They didn’t have any generic O-Rings for my filter, so I ended up shelling out $20 for a loop of rubber. I recommend seeking out the cheaper, generic alternative. Below are some pictures of the procedure I followed to change out the O-Ring seal on my cartridge filter. You can click each image to enlarge, and I’ll report back in a few days about whether or not this fixed the air-leak.
