Why does the filter basket never seem to catch anything and it never reads to need to be backwashed...but the water is still not clear....what are we doing wrong?

Because of the size of the filter - 18", I would presume this is an above ground pool?
  • Do you have a skimmer?
    • If so, put some leaves, larger organic debris, etc. into the skimmer. They should end up in the basket of the Hair & Lint Pot!
    • That would prove your question to be either working or not.
  • If you don't have a skimmer, then you have a suction port in your pool.
    • Let that suction port suck some larger debris that would stay in the basket. Again, you will prove or disprove, whether debris is getting to your pump basket (Hair & Lint Pot Basket).
How long has your pump & filter been operating? How long do you let your pump & filter run per day?
  • It should run at least 8 hrs per day.
  • If cloudy, you should run continuously until clear.
How long has your water been turbid/cloudy?
  • Use a clarifier, Natural preferred, like SeaKlear, daily at recommended dosage, until clear
What is the pressure? Are you saying that it is the same pressure as Day 1, has not climbed at all? What do you mean: Does not read that backwash is needed? What in your understanding is: "Time to backwash the filter"? You should know the "Starting Pressure" of your Sand Filter!
  • When sand is absolutely clean & free of any grime and sticky residue.
    • Just added media, when just installed is the best time to make a note of the starting pressure on a working pressure gauge.
  • When the pressure rises 8-10 lbs. over starting, time to backwash!

We need to change the sand in our filter ,it is a sw256t hayward ,but dont know how to remove other sand,does anyone know how?

Once you have the plumbing disconnected and valve removed, Use a shop vac. Works well. Once the sand is almost all removed, you can tip the tank over & rinse out with hose for the rest.

Where is the valve for the backwash?

The Backwash option should be part of the Multivalve at the top of the unit. If it is not please post pictures here for further instruction.

How do I check the backwash valve?

Is it a vari-flow valve? If so with the pump off set the valve to "filter" then you can remove the screws on the top of the valve and remove the assembly. The gasket that usually goes bad is the "spider gasket", it looks like a pie-chart. Check this gasket for any tears or bends in the rubber, if you see any replace it. Turning the valve with the pump running will cause these gaskets to go out

Water coming out of backwash hose after I return

Thank you for posting your question here on Fixya.com.

You need to replace the gasket inside the valve to stop the leak. The gasket kit is pretty cheap and not too hard to replace. We can try to get you the part number if you can post the valve brand and model. You should be able to call any local pool store with the brand of filter and get the part you need without any trouble.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. You may also contact me thru our website at www.arrowpools.net. Positive feedback is appreciated once your problem is solved!
