Jacuzzi 250L filter not backwashing

Postby mmeyer3121 » Mon 17 Jun, 2013 10:58

I have an ancient jacuzzi 250L sand filter that has stopped backwashing and rinsing. The pump will continue to run but the basket area empties of water. The pump basket will fill in "filter" mode but it does so in spurts. Pool water is extremely cloudy. 4 ft pool and cannot see bottom. The skimmer would stop pulling water at times over the past couple of weeks and I would backwash/rinse and the skimmer would work like normal. Need help, please!

When was the last time the sand in the filter has been changed? If it has been more than 3 years I would start there. The sand in a filter can harden over time and cause major pressure problems. Once you have the old sand cleaned out of the filter, check all the laterals inside and make sure none of them are plugged or broken.
