    Intex sand filter low flow

    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...

    Filter pressure not restored completely after backwash

    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...

    Ants in the sand filter-how to get them out

    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...

    Brand new sand filter question

    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...

    Sand Filter and Pump Matching

    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...

    Cloudy weeks into SLAM added DE...

    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...

    Hello from Michigan… issues with pool sand filter backwashing

    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...

    Sand Filter leaking from Clamp

    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...

    Hello!

    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...

    Easiest way to put sand back in sand filter?

    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...

    Pentair SD80 replaced with TA-60...errr TR-60

    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...

    Is 1/2hp pump right for a 1,715 gallon pool?

    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...

    Can't tell if air in pump or air leak or overthinking

    Hey guys, I'm not sure what I'm looking for. I'm on day 4 of a SLAM and I thought I would add some DE powder to my sand filter to speed it along. The filter is a 22 inch ecokleer sand filter that says it takes 250lbs of sand. The sand was put in last year when the pool was installed. Pump...

    Weird Blue Stuff in Sand Filter

    We recently bought a house with an in-ground vinyl pool. Been working on getting the levels right for a few weeks, but this afternoon after adding about 8 lbs. of borax (pH is currently < 7), I noticed some cloudiness in the water. After doing some research here on the sand filter and seeing...

    Mixing filter balls and sand in a sand filter

    Hello, all! I am just about to set up my first sand filter. I went for filter balls, since I don't envy hauling around any more wet sand than I have to. But the company that sold it to me suggested that I add a bag of filter sand to the bottom of the filter, to support the laterals. My concern...

    Pressure shooting up after new sand and laterals

    Had a small fissure in the standpipe of my lateral assembly, so I had to swap out the assembly. While I had all the sand out, I decided to go ahead and put new sand in there. It’s never been changed since I’ve owned the pool and who knows if it was ever changed by the previous owner. I know the...

    No manual pressure relief on S220T, right?

    So this has been my first foray into repairs in which I have to drain the filter. I’m pretty sure I know the answer to this, and I’ve heard this about pro-series filters generally, but I just want to make doubly sure. The S220T has an auto pressure relief, right? I’ve never come across a...

    DE in sand filter not changing pressure

    I followed the guide, but even after two full cups of DE the pressure in my filter did not rise at all. The guide didn’t really indicate whether going beyond two cups was safe or not, so I have not tried any more than the two cups. Why am I not seeing any change in pressure after adding two...

    Multiple Questions about Maintaining Older Pool

    Problem with deep cleaning the sand filter

    I watched the video for how to deep clean the sand filter. It DEFINITELY needed it but in the process of cleaning it, the center tube that attaches to the laterals made its way to the top. Now what!? Do I have to empty to get it to the bottom again? I tried shimmying it down and only got about...
