First post here. Have been reading all the great advice, tips, tricks etc and decided to ask the professionals. Woke up to a large amount of sand in front of 3 out of 4 jets. We have since had filter and multiport valve repaired. Wondering if I can just vacuum all that sand on filter mode. One of the pool guys said yes, it will settle back into the sand filter. But everything I'm reading on internet says vacuum to waste. Either way it has to run through the pump, which is my concern. Will doing this cause any damage to pump? Thanks in advance!
