SOURCE: When I turned my pump off to backwash and then

sounds like a bad start capacitor, or there is something (rock, sand, or some debris) caught in the impeller.

The start capacitor not working will cause your motor to hum, then it will overheat and trip the high limit. It won't attempt to come back on until it has cooled. It's a common problem.

try clearing the impeller first, if that doesn't work and the motor shaft spins freely, then it's a capacitor.

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!

How do i backwash an Intex pool?


You can only backwash a "Sand" media filter.
If it is a cartridge element style, it needs to be removed and either hosed off with a pressure nozzle on your garden hose, or replace it.

If you have a Sand filter, you should have a multipart style valve that you would only turn when pump is off and place it into the properly marked "Backwash" position and then turn pump on for a few minutes, then turn back to "Filter" after rinsing.

How to use backwash to waste


When the filter get clogged the pressure in the filter increases and there is less water flow returning to the pool.
If your filter is a sand filter, when you turn the valve to backwash and turn on the pump it reverses the water flow in the sand filter to flush the dirt out of the filter to waste. Look at the window openning in the waste pipe and keep the backwashing goinging until you see clear water.
Then turn off the pump and move the control valve to Rinse, turn on the pump for a few minutes, this returns the water flow back to normal but the water goes to waste to make sure the sand filter is clean.
Turn off the pump and move the control valve to filter and turn on the pump. This mode is the normal operating mode and the pressure gauge in the sand filter will show a drop in pressure.
Some pressure gauge shows a red section to indicate when backwashing should be carried out.

When I turned my pump off to backwash and then turned it back on it made a humming noise then stopped running. Now it is doing nothing. what could the problem be?

Pump was working fine but now only makes a humming sound.


First, Yes you need to turn off the pump when switching from filter to backwash. And Yes again get a heavy guage cord so you don't burn out the windings in the motor. The thermal will usually stop the motor from catching fire after the damage is done.
Now your problem; Water can be put under pressure but you can't compress it. Air on the other hand you can compress. If you had any air in the tank and didn't get it out while switching from filter to backwash. When you shut the pump off that air will expand at a rapid rate and rush back through the sustem. This will cause the impellor to spin off the shaft inside the pump and bind up. If you take the pump apart and look this could be your problem.More often than not your threads on the impellor will be runed so yopu probally need a new one and a new seal but cheaper than a new motor. If you take it to a pool store they can do this for you for a small charge or just the price of parts. While you have it there have them check to see if you can get a left hand thread impellor screw to lock the impellor on so this won't happen again. Most motor shafts are already drilled and tapped for this. The left hand thread can't spin off and will keep the impellor in place. Also be careful not to **** air when draining water from pool.Good luck.

Lost manual and forgot how to backwash filter.


Shut off the pump, press down and rotate the valve handle to point to the backwash setting. Turn pump back on and run until water coming out is clear. Shut off and rotate handle to rinse setting, turn back on and run for 15 seconds. Turn off and rotate handle to filter and turn back on.
