Backing washing is completed via first turning the pump OFF. Note: Always flip the pump off whilst shifting the clear out multi port valve. Once the pump is off, flip the multi-port valve at the clear out from the ‘clear out’ place to the ‘backwash’ place. Once the clear out is within the backwash place flip the pump again on. The water is then reversed throughout the sand via the pump. The grimy water will get despatched out the waste line (most often into the backyard). High concentrations of chlorine can kill grass so you will need to know what the chlorine stage is within the pool whilst backwashing. A 1 to two ppm vary must be protected it steer clear of killing the grass. Once the water popping out the waste line is turns from grimy to wash (would possibly take as much as three min.) flip the pump back down. Once the pump is off transfer the multi-port valve again from the backwash place to the rinse place. Turn the pump again on and let it run for roughly 20 seconds. Then flip the pump back down and transfer it to the clear out place.

Lets recap the backwashing steps:

Filter Position-> Pump Off -> Backwash Position-> Pump On for two min. ->Pump Off -> Rinse Position-> Pump On for 30 Seconds -> Pump Off -> Filter Position

Diatomaceous earth filters:

Diatomaceous earth filters use grids inside of covered with diatomaceous earth or DE for filtration. DE filters have the benefit of filtering to the best debris or microns. However, they’ve been thought to be probably the most trouble to perform. For right kind operation of a DE clear out it should be grew to become off for roughly four hours on a regular basis. This is to permit the DE to drop and be recoated when the pump comes again on.

Back washing a DE clear out:

Like sand filters additionally they require backwashing when the force rises to about 6 pound above the standard running force. After backingwashing you should recoat the clear out grids with new DE. This is completed via feeding DE throughout the skimmer so it will get pumped into the clear out tank. DE is a white powder substance that should be bought at pool retailer. About two times a 12 months DE filters must be taken aside and the grids wiped clean. Most DE filters have a multi port valve on them used for backwashing. Backwashing is a simple procedure. Backingwashing is completed via first turning the pump OFF. Note: Always flip the pump off whilst shifting the clear out valve. Once the pump is off, flip the multi-port valve at the clear out from the ‘clear out’ place to the ‘backwash’ place. Once the clear out is within the backwash place flip the pump again on. The water is then reversed throughout the grids via the pump. The grimy water with previous DE will get wasted out the waste line (most often into the backyard). High concentrations of chlorine can kill grass so you will need to know that the chlorine stage within the pool is low whilst backwashing. Once the water popping out the waste line turns from grimy to wash (would possibly take as much as three min.) flip the pump back down. Once the pump is off transfer the multi-port valve again from the backwash place to the rinse place. Turn the pump again on and let it run for roughly 20 seconds. Then flip the pump back down and transfer it to the clear out place. Now its time to recharge the DE within the tank. Refer to the label at the clear out for the correct about of DE to be added, it must say what number of kilos are required for a recharge. Turn the pump again on and cross over to the pool skimmer. Add the really helpful selection of kilos to the skimmer slowly. It is perfect to make a slurry in a bucket then slowly deficient it into the skimmer so steer clear of clogging. At this level this is a excellent concept to check out the go back line within the pool to ensure that the DE is being stuck within the clear out. If you could have white powder spraying out the go back jets within the pool then you understand you could have an issue in you grids or the valve is about within the improper place.

Lets recap the backwashing steps for a DE clear out:

Filter Position-> Pump Off -> Backwash Position-> Pump On for two min. ->Pump Off -> Rinse Position-> Pump On for 30 Seconds -> Pump Off -> Filter Position-> Pump On->Recharge clear out with DE from skimmer
