Why are you rinsing the filter daily? That is not recommended.
The lack of water this summer made me "abandon" the pool, no possibility to vacum due to low water level.
Its the campo, lots and lots of dirt flying around.
The "street water"/mains, is dirty, dirty water.
And I noticed that if I didnt rinse the filter, the next day when i start to filter, some dirty water is the first to squirt out of the nozzles.
Even when the pool is clean and the water nice and clean, I have to vacum every 2 days. And rinse the filter.
P.S. its a dominican built pool, I have had tons of trouble.
The buisness who built it, connected the pump to 110 instead of 220......duuh. bloody thing was always overheating.
Through them I got an old guy to come round. I wanted a cristal clear pool for a bunch of family and friends comimg over. Diagnostic. Filter has a problem. He unscrews everyrhing and proudly said it was so clogged up with sand, no wonder it wasnt filtering.
But, but, but its a SAND FILTER !!!!
