We received a storm a few nights ago and the temp dropped so we have a ton of leaves in our pool. Unknowingly, my wife vacuumed up a bunch of leaves trying to clean the pool. The gauge now reads 0 psi and when I went to backwash, the water pressure was very low. I cleaned the basket in the pump and think that some leaves got into the plumbing and is blocking the flow. I have a DE Hayward filter and Hayward pump for a gunite inground pool. I need to fix the problem before I can close my pool. Thank you.
