The backwash valve is the valve which is mounted on either the top or side of your filter tank and are specifically used clean sand filters or DE filters. One of the most popular filter manufactures in the world is Hayward Pool Products who also makes quite a few backwash valves .

  1. Shut off pump, roll out backwash hose, check waste line for any closed valves .
  2. Turn multiport valve handle to backwash, or slide a push pull valve .
  3. Turn on pump.
  4. Backwash until water runs clear, about 2-3 minutes.
  5. Shut off pump, turn valve back to filter, turn filter back on.

Consequently, what is a backwash valve?

The backwash valve is the valve which is mounted on either the top or side of your filter tank and are specifically used clean sand filters or DE filters. One of the most popular filter manufactures in the world is Hayward Pool Products who also makes quite a few backwash valves.

One may also ask, what is a push pull valve? PUSH - PULL VALVES. The push - pull valve is the simplest type of backwash valve and the easiest to operate and maintain. Note that the valve operation is often opposite on sand versus DE filters on PacFab (Pentair) and several other filters. On StaRite filters the filter mode is always down and backwash is always up.

Keeping this in view, why do you need to backwash a pool?

" - Similar to a vacuum cleaner, air conditioner filter, or your kid's bedrooms, your pool filter collects dirt! Whenever the filter fills up with the dirt/debris it reduces the flow of water to your pool. Low flow = poor circulation which will lead to algae in the pool.

How long do you backwash a pool?

Set the filter valve handle to the BACKWASH pool position and ensure the handle locks in place. Turn on the pump and backwash for 2 minutes or until the water in the sight glass (located on the filter) is running clear.

Do I need to backwash a cartridge filter?

There is no backwash valve on a cartridge filter because cartridge filters aren't built for backwards flow. Instead, the pump is shut off, air bleeder opened to drain the tank, lid removed, cartridge(s) removed, hosed thoroughly top to bottom, and replaced.

How do you backwash and rinse a pool filter?

Turn the pool filter system on and allow it to rush out of the backwash port and through the backwash hose for two minutes or so until the water in the sight glass runs clear. Turn the filter off again and set your multiport filter valve to the “Rinse” position.

Why is my backwash valve leaking?

Sometimes you will see water leaking out where the valve shaft goes into the body of the valve. This indicates a bad shaft o-ring on the valve. If water keeps trickling into the backwash line, even 15 minutes after the valve has been put on filter, then there is probably a bad gasket or o-ring on the valve.

What does backwashing a pool mean?

Swimming Pool Maintenance Backwash or backwashing is the process of thoroughly cleaning a swimming pool's filter by a method of reversing the flow of water to flush out contaminants. This way, you don't have to clean the filter manually, and it usually takes just a few minutes.

Does backwashing remove water from pool?

Backwashing can take only a few minutes to complete, but for a typical pool, it consumes approximately 200 to 300 gallons of pool water! So, while your filter is losing unwanted dirt and debris—your pool is losing a ton of water.

How often do you change pool filter sand?

On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.

How do you flush a pool filter?

Turn off your pool pump. Push the filter handle down on a push-pull valve to move it to the backwash or back flush mode. Turn the power on to your pool pump. Pull up the push-pull valve to return to the filtering mode. Turn on the pool pump to allow the multiport filter to rinse the sand or earth. References (3)
