I had to replace the whole top on my sand filter about a week ago and yesterday it started making a lot of suction sounds ,on filter, somewhere inside and around the backwash line and air relief valve. There is no way to see iwhat is happening out of the backwash line (PVC plumbed into the ground) and I open the relief valve but it is a strong spray. The pressure has not changed any and there are no leaks. Could it be defective from the store and should I just open it and check the spider gasket?
Thanks Kay
