Your pump has probably lost its prime. This is either because it got too much air or not enough water. Try priming. This should make your pump start working again. Any time pool pumps have to be services, they need to be re-primed. In case you are not sure how, remove the pot lid and fill the pot with water. Re-add and clamp the pot lid. Open the air release valve on the filter and stand clear. Turn on switch or time clock. When water comes out of the air release valve, close the valve. If it is a two speed pump, make sure it is on high speed.

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!

My pump is on filter but is draining the water out please help


The water Has to be going out the 'backwash' or 'waste' line.Either that or you have a leak in the plumbing. If the backwash/waste valve is set in the 'filter' position and there is still water escaping through the backwash/waste line, it means that the o-ring or spider gasket needs to be replaced or re-seated. If it is a multi-port valve (one that you spin to select the setting as opposed to a 'push/pull valve) you can try shutting off the pump; do a complete turn, 360 degrees, from the 'filter' setting all the way back to the 'filter' setting. This sometimes helps the spider gasket re-seat

Where dothe hoses go


Suction from the pool goes into the front of the pump housing ... Discharge from the pump goes to the filter. If multi-port, there is a suction and a discharge port identified. If it is push/pull, Top port goes to waste, center is water in, bottom is water return to the pool.

Pool water is suppose to go into the top of the filter and out the bottom for return to the pool.

When manipulating the valfe (multi-port or push pull), ASSURE the pump is OFF! If multi-port valve, only turn the handle clock-wise.

Need to know how to backwash the pool filter


Depends ...

There are two primary valve styles ... a "multi-port" and "push-pull". Never change a valve setting with the pump running.

Multiport has a handle that goes around in a circle (only move it clock-wise). You should go to your pool place to identify this kind of valve and get new lables. Push-pull goes up and down. Up is filter - Down is back wash.

If you will study your system, some things will become evident to you .

Your pump pulls water from the pool through the pump ... out of the pump into the filter. Through the filter, back to the pool. You might be heating the water (would be after the filter) and you may be adding sanitiser (after the heater). One suction - two discharges (oh, the other discharge is to waste.).

Recap ... water out of the pool into the pump - out of the pump throuth the control valve to the filter - out of the filter to the heater then to the sanitiser then back to the pool.

Any help?

I have a 24 x 52 intex above ground swimming pool and I can't get the filter to properly work. It is taking water in but not putting water out


You must open the little valve on top to let out the air, then screw it back on when water reaches the top,  and ensure both gates are open.

Sand filter not catching little debris


Filter is being bypassed at backwash valve, due to poor spider gasket in valve, or there is a broken lateral in bottom of sand filter, causing debris to return to pool..
