Want this question answered?
intex sand filter is not working on filter only working on recirculate position.....what should we do
Usually in line with the return line to the pool. Hatawa
How do you back flush a pool filter?
Hmmm, do you possibly mean the back wash valve on the filter? This valve has many positions to choose from especially for sand filters. Filter, back wash, drain, drain to waste, filter bypass, closed. They are pretty much self explanatory. Normal position would be the "filter" position while the pump is running and the filter is working. Ken
Should be set to Filter in normal circumstances, if particularly soiled, set to waste to save excessive dirt in filter.
There is no filter at the bottom of a pool. Perhaps you are looking at the hydrostatic valve which is there in case your pool is emptied and Will make sure that the pool wont float in ground water.
Back wash valve when the pressure before the filter becomes to high usually indicated in red on the gauge the filter needs to be back washed.
Need more specific info A multi valve pool filter is a common configuration of valve and filter for a swimming pool system. The piping into and out of the filter is attached to a multivale. A multivalve has has several positions. One type of multi valve has six positions: backwash, waste, filter, closed, rinse and recirculate. (These valve positions are used on a DE filter. A sand filter may be different.) Use the filter setting in the nromal operation of your pool. This setting receives water from the pump and directs it to the dirty side of the filter media and then receives weater from the clean side and directs it to the pool. Use the Backwash setting to flush the DE from the filter and to a drain. Use the waste setting to flush water directly from the pump to the drain. The closed position is, well, closed. Rinse? Recirculate?
Backwash valve is leaking by. More than likely it is a bad oring inside the valve. Or it was not place back into recirc mode completely. or you may have a leak on the return side of the filter. That includes all the plumbing from the filter or heater to the pool. The back wash valve may be obvious if the waste line ends close by. The back wash valve should be placed in the "filter" mode not the "recirculation" mode. K
I'm not sure about a pool, but with a hot tub, backwashing refers to reversing the flow of water through the filter so as to flush the filter of the sediment it has collected. There should be a valve on the inlet side of the filter that diverts (reverses) the flow of water. Assuming your filter is working properly, you should rarely have to drain and refill the pool. Hope that helps. Call a pool service to have them do a show and tell about your pool. The one time charge will be well worth it. Take a lot of notes because you will never remember all the advice.
It should be on "FILTER"
The cleaning schedules varies from filter to filter, but a general guideline on any swimming pool filter is to take a reading when the filter is clean, then clean the pool filter when the pressure rises about 10 psi.
