sand filter

Just closed the pool a few days ago. It took forever waiting for the water temp to get under 50 degrees. The sand filter has been in use for around 20 years. I estimated based on the manufacture date for the serial number. Based on how fast debris settles on the bottom of the pool I've...

If I leave the water undisturbed for 24 hours it is perfectly clear. Upon any movement in the water, a “cloud” appears. When I look into the water after starting to vacuum on waste, I can see millions of tiny particles that appear white in the water. I have vacuumed on waste several times and...

First of all, a thanks to this forum - I bought a home with a pool having never owned one before last season, and what I inherited was a 30 year old pool that had become an abandoned swamp. Winterized but uncovered for at least one year, possibly several. I had to learn how to recover the...

I'm in the middle of putting my Hayward S244 Sand filter back together, and the last piece I'm struggling with is how to put the drain screen in. It doesn't fit snug on the inside, so maybe it just needs to be glued/caulked into it? I see the newer filters have a screw-in style screen, but mine...

I just had the bottom elbow assembly fail for me on my really old Hayward S244S sand filter. I was able to find the parts online that I *think* will fix it, but it'll be in the neighborhood of $250 by the time I get the replacement parts + replace the laterals while I have the sand out (plus the...

My Intex SF70110-2 sand filter (purchased 2 months ago) began leaking out of nowhere. I have taken the pre-filter housing apart, and lubed the o rings, but it still leaked. Took it apart again and wrapped the o rings in Teflon tape, added a bit more lube, and eased the pre-filter housing back on...

would love to get some help as this is all new (and very frustrating!) to me. opened my in-ground vinyl pool for the season. noticed a ton of sand in the pool - had company over to replace valve and sand in my filter. sand still coming into pool. company came back did a thorough backwash and all...

Hey all, new to the forum here 👋 I recently bought a house with a pool and have been doing all maintenance myself, following the TFP method. It’s all going great! The only thing I can’t quite figure out, is how to backwash my sand filter. I’ve searched the forum and watched a bunch of videos...

I've read the primer , and my local discount store stocks Mystic White, but it does not (to my thinking) clearly indicate on the bag what the size of the granules are. I think maybe this is the .80mm based on the "80" on the side. Is that right? Even the HTH sand that is repeatedly mentioned...

Hi, winterizing the sand filter in ground pool in the home we revert purchased. I read through most posts and was able to blow lines ( I think) Looking for help , Sharing the photos 1. Removed plugs on the filter and pump and let the water drain. What am I supposed to replace all the...

I have a Pentair Tagulus TA-60D2 with 2inch pipes on the top mount filter valve. I recently had the filter sand replaced, and since then: 1. The water pressure has been low (6-7) PSI when filtering 2. The filter does do some filtering, however the PSI never increases as the filter gets dirty (it...

I bought a home with an above ground pool. It's my first. I had to replace the pump, but the filter seems fine. But the label on top that shows what each set of the dial does has withered away. I know where the backwash setting is, but that's it. Can I reorder a label? Do need to make my own...

Hi guys, I'm a relatively new pool owner (two seasons now), and I have two potentially-related questions. Background info: Aquasport 52 (17' x 32', oval, ~14k gallons) Flat bottom, no deep end Two years old, set up last April I live in north Alabama, pool is in partial or full sun all day...

I bought a house with a pool last fall and ever since reopening it this spring, it's seemed like the filter is barely catching anything. The pump runs and moves water fine, but lots of debris (pollen, small leaves, etc.) comes back out the return ports into the pool (but no sand). The filter...

Hi, I have an intex sand filter. When I try to bleed the air when the pump is on filter mode, the strainer basket starts to fill up with more air. Why?! When I bleed the air with the pump off, the air bleeds out just fine. I have checked o rings, unions, water line is good. I have not seen...

3rd year with the sand filter/salt chlorinator combo. I love it! I just started my pool a week ago for the third year. It seems to work fine while it's filtering for a few hours but then when it goes to auto filter the next day there is next to no flow. I decided to back wash it again and then...

We recently opened our pool and SLAMed to completion. We then used a combination of brushing and robot cleaner to get most of the debris out. Last night the filter gauge was reading about 16 psi and we did another brush. This morning the pressure was 26-27 psi when we backwashed our sand filter...

I opened the pool yesterday, for the first time ever on my own. I mean, my husband and son helped me with the gigantic loop loc cover and some skimming but otherwise, it was me doing the dirty work out there. You know, sticking your hand in the skimmer with god knows what decomposing in...

I have a brand new Intex 20 ft above ground pool with a sand filter. When I operate the filter it runs good for about 45 min and then the water flow trickles down to nothing. The pressure does not change that much. The water is clear and I think my chemicals are good.. If I switch the filter to...

Hi pool people, I'm replacing our ancient 24' round above ground with an equivalent and looking to replace my filter at the same time (had an old crappy DE that is undersized and ruined). I'm interested in doing sand filtering, from the numbers I'm seeing, it seems like I have to get a very...

Hello all! Struggled with our new pool last season, did a terrible job over the colder months and started out this year as a TFP devotee, already spreading the gospel! We started our SLAM a few weeks ago. First got our PH down to 7.2. Initial CYA tests weren't reliable (so we were slamming at...

Hi everyone. I am a new pool owner after buying my first house. I figured I’d enjoy pool care more than yard work so I picked a small home with an inground pool. I started doing a lot of research and have ended up on this site many times and finally decided to register haha. Thanks for the help...

I just got the hayward sand filter leaking from the clamp. It started recently. I also find the lever of the control valve hard to move around. Do I replace the control valve, O ring and the clamp? Or is there anything else that I am missing. I have added a video below for understanding the...

Hi, TFP. Please help me set my flow rate on a schedule that will keep my energy bill down and my water clean. A few pertinent details: I have solar panels on my home My time of use pricing with PG&E means 4-9pm is "peak pricing" I have a spa spillover feature, but nothing else My pool filter...

Hello, TFP users. I'm RJ and I own a home that came with a 24,000 gallon sand filter equipped pool. It has a spa spillover feature, but nothing else. From what I can tell, it's a pretty old pool since it features a pop-up cleaning system. There are some light cracks in the plaster that I hope to...

Hiya - I'm new here. I have read many posts and responses about algae. I'm not seeing anything that is what I experienced, so I thank you in advance for your patience and help with another algae question. First - yes, I know I need a test kit, and I do not have one yet. So... while I wait...

I have an 9 x 18 ultra xtr pool with the intex 1200 gph pump and sand filter; I also have the intex CG2667 SWG (which can be used with a 700-3200 gph pump). I LOVE, LOVE, LOVE my pool. (I am a first-timer, can you tell?) It is in our shaded, wooded backyard and I keep an intex solar cover on...

Haha, so I was replacing my cracked 4-way valve with my new one, and it was stuck on the stand pipe. I ended up accidentally pulling the stand pipe out. Luckily, I own a wet/dry shop vac, so removing the sand took less than 5 minutes. What’s the easiest way to add it back?!? The sand is...

I have a Pentair SD80 sand filter that was installed in 2013 (at least per the pool store, we bought in 2015). A small pinhole leak started right at the end of the season last year and I forgot about it over the winter. This spring I patched with epoxy to buy time to research, but as I've...

Hi! I have an Intex Prism 12’ x 30” pool that has two lines into the pump and one line to the pool. The connectors and hose are 1.25”. My pump is 1/2hp with a sand filter, which came as a set. Is this too powerful? I know I’ve asked something similar before, sorry — I have OCD and I feel...
