I have a Hayward sand filter that typically operates in my system at about 17 psi. This has suddenly dropped to about 12 psi. The filter is 12 years old. The motor speed seems normal and the return flow to the pool feels normal, so I’m wondering if there could be a problem in the filter where...

I have a 12 year old Hayward Navigator, whose lackluster performance I've been tolerating for too long. It can barely (and rarely) climb out of the deep end, and never reaches some areas of the slopes. I want to replace it with one that is not only able to cover the entire bottom efficiently...

I just did a deep cleaning of my filter using a hose. I believe I have lost a good bit of sand in the 11 seasons of operation without ever adding sand before. I have a Hayward Pro-Series S244T that is supposed to hold 300 lbs of sand. Problem is, I see no need to remove the old sand and add...

I still need to score 5 more boxes of borax after cleaning out 2 different Walmarts 3 times, and have 8 gallons of MA on hand. First, following the sticky for adding the borax and acid, I need to adjust my TA to between 70-80. It is currently about 90 to 100, and my pH is 7.5. I understand...

I recently replaced my single speed motor with a 2-speed and wired the SWG to produce only on low speed. Previously with the single speed motor, I would see very small bubbles coming out of the returns when the SWG was producing, and always wondered if I am losing chlorine from any bubbles that...

I just bought a new 2-speed motor (A.O.Smith Century SP1610Z2MC) to replace my old single speed motor. I also bought a Intermatic P1353ME timer to replace the current manual on/off switch. I already had a Goldline Controls Aqua-Rite Chlorine Generator that is wired to receive power whenever...

I switched to a salt chlorine generator system a couple years ago, but my old chlorinator is still plumbed in. Can I put granular CYA into the chlorinator as a means to dissolve it, perhaps more quickly than the sock in the skimmer method? Otherwise, I'm thinking of making a PVC rig to screw...

First let me say I wish I had all that advice for the previous 11 years of pool ownership! Glad I found this site. Here's my question: I always thought vacuuming the pool on waste as soon as possible after killing the algae was very important to reduce the amount of biological material in the...

I recently fired up my 11 y.o. pump for the first time since November, and it screams like a banshee after initially humming and not turning. A little "percussive maintenance" got it turning however. I suspect the bearings are on their last leg. The seal was leaking last season, so maybe that...
