Sand pool filter has no pressure

Sand pool filter has no pressure. Any ideas? Inground pool with 10-month old Hayward sand filter. I vacuumed the other day on the “waste” setting… and ever since it has had no pressure and not circulating at all.

Pool place thought the sand might need to be replaced already. Shouldn’t that only need to be done like every 5 years.

Any other ideas on what the problem could be?

    The pump has lost it prime. While vacuuming you got some air in the system and the pump is sucking air and not water. Try to figure how to re prime the pump. Some pumps have a visable filter the the top can be removed. If so take the top off and fill with water, you may have to do this a couple of times. You can email me direct if you like. email: Regards, Dale

    Our sand filter was loosing suction. The pool sweep stopped working. It when from low , to no suction over night. We can’t get it to prime and we can’t back flush.
