I finally got my new de filter installed yesterday. I ran the filter over night and already i could see a difference. My question is the pump (1.5 HP) is working fine until I use my cleaner(Hayward nav) I connect the vacuum hose to my skimmer and it begins vacuuming in the pool. I noticed shortly after air bubbles in the return lines. This only happens when I connect the vacuum. twice now, Ive left the vacuum do its thing only to come back and find it floating and the pump running dry.
what could be the cause of this? we just bought the house and inherited a 18k gunite pool. the new filter i got is a pentair de 48. Ive had to backwash three times already in 2 days.
I also dove down because my pool has never had a main drain cover. with the pump running I dove down to check the Main drain and put my hand directly over it and absolutely felt no suction.
are these two problems related?
