Tip

Backwashing A Sand Filter with A Push/Pull Slide Valve or Multiport Valve


Lots of people are first time pool owners and pool professionals forget to teach these "newbies" about the simplest aspects of pool ownership.

One of the biggest questions we receive from new homeowners is "How do I go about backwashing my sand filter exactly?"

It doesn't matter if you have a Hayward, Pentair, Jandy, Sta-Rite or any other number of Sand Filters on the market they all utilize the same basic valves for backwashing; a push/pull slide valve or a multiport valve.


To backwash with a multiport valve:
1) Shut off pump motor.
2) Press down on valve handle, rotate valve from FILTER to BACKWASH position.
3) Roll out any backwash hose or open any waste line valves.
4) Open air bleeder assembly on filter, and turn pump on.
5) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
6) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
7) Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 15 - 25 seconds.
8) Shut off pump motor and move multiport valve handle to FILTER position.
9) Turn pump back on and note lower pressure.
10) Roll up backwash hose so the dogs use it as a chew toy.


To Backwash a sand filter with a slide valve:
1) Shut off pump motor, roll out backwash hose.
2) Twist to unlock plunger T-handle, push or pull(depending on manufaturer) the plunger 2" - 3".
3) Open air bleeder assembly on filter, and turn pump on.
4) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
5) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
6) Shut off pump motor and push T-handle back down into locked position.
7) Turn pump back on and note lower pressure.
8) Roll up backwash hose.

Now you are a backwash Guru!

Hayward vari flo valve


Does it filter? Does the pump have full prime? I'm not clear about how when the valve is put in the backwash position nothing happens.

Hayward sand filter


Reference your pressure gauge as the 12:00 position. Going clockwise-
12:00 is Filter, normal running position
2:00 is Waste, water goes from pool and exits the waste line, bypassing filter.
4:00 is Closed, used only when servicing equipment
6:00 is Backwash, reverses water through the filter and goes out the waste line.
8:00 is Recirculate, water bypasses filter and returns to pool.
10:00 is Rinse, water goes through filter and exits to waste line, used briefly after backwashing to clear sediment from filter.
Note that the "pointer," not the handle that you grab, indicates which setting you are on.

How to know what cycle to use or when to use filter, backwash or rinse?


during normal operation, your multiport valve should be in the "FILTER" position.

Once the pressure in the filter reaches 10psi more than what it was when the filter was clean, you should backwash. turn the pump off, press down and turn the multiport valve to backwash. turn the pump on and watch the effluent water until it goes from dirty to clean. Then place the multiport valve to the rinse position, this will rinse any remaining dirt from the top of the filter and valves so that it does not return to the pool. Once the water comes out clean, return the valve to the filter position.

Do not turn the valve while the pump is on, always make sure to turn the pump off before servicing any equipment.

Wicor high rate sand filter P20. When I have it on "filter" there seems to be some water starting to leak from "backwash" hose.I only let it run maybe 30 seconds. Not looking for it to blow out any seals...


If it has a multiport valve, most likely the spider gasket inside has damage or has come out of place. A broken stem spring can also cause water to bypass out the backwash due to not having enough force to seat the seal. Take the multiport apart and check the spider gasket and spring.
