I have an older pool, and it has a purex triton whisper flo pool pump and don't know how to back wash. I am not seeing anything that says backwask or a lever to turn. I need to back wash because my filters have been acid washed and the pressure is till too high. Can anyone help me?? Thank you!

SOURCE: my pool sand filter pump isnt filtering the water

sounds like the sand has clumped together inside filter. you can open filter and replace sand charge or dump into wheel barrow loosen sand and flush clean with hose and put back in

You can not backwash a catridge filter. If cleaning them doesn't work they need to be replaced. A common 'issue' with cartridge filters - replacing the expensive elements every few years. There is no other way to clean them that will not in turn destroy the filter material in the process so new ones are your only choice.

Total alkalinity can be lowered by adding muriatic acid or sodium bisulfate. Acid may be added in doses of up to 1 quart per 10,000 gallons. Total alkalinity tests and further required additions of acid can be made every 2 hours.
