How to replace filter sand


  1. Open air relief and drain plug to allow air into filter and water out.
  2. Take apart filter, remove all nuts/bolts/screws/fasteners and separate the filter. Could need some force to separate
  3. Use a shop vac to suck out the sand or a cup, be careful not to be too violent, if you damage laterals sand will go into the pool
  4. Check the laterals, No cracks or damage
  5. Close drain plug.
  6. Go to pool/home store buy POOL SAND. Amount required should should be posted on the filter somewhere. any extra will go into pool, or backwash out.
  7. Add some water about halfway of the filter, slowly add sand back into filter, dont be too violent. be careful not to get sand into any piping it will go back into pool.
  8. Prime the pump(add water to it) backwash the filter for 2~3 minutes
  9. Close air relief
  10. Run pump on normal open air relief as need to let excess air out .
Done!

How does Hayward Sand filter work


Excellent answer Robco, One slight variation of an explanation about "waste"... When in this mode, water never actually enters the filter tank, it goes in the valve from the pump, and out of the valve through the waste port.
Very similar to the "recirculate" mode, it comes from the pool with the help of the pump into the filter valve, and right back out the filter valve, without ever going into the tank, and back to the pool via the return port.

Pump is blowing cloudy water back into pool


Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

if the debris your are trying to vacuum up is more fine than the sand can catch (specifically with algae or dead algae), it will blow right through the filter. there is a setting on your filter called either drain or waste. when using this setting the water completely bypasses the sand and comes straight out the back wash outlet. this is a rather tedious task as you lose alot of water, but it is the only way to remove this type of particulate. make sure the pool is overfilled when you begin. good luck!
