We purchased a doughboy filter tank off craig's list since the old one developed a leak. When we picked it up, the owner "rolled" the filter on to its side and "rolled" it to our car. I knew that was a "no-no" realizing sand could get in the standpipe.
So, now I want to see if the new tank works, the multi valve port is full of sand and I can't see in but I'm thinking there is sand in the pipe.
If I reinstall the old multiport on the new tank and run the pump with sand still in the filter standpipe, will it cause any damage?
Or will it just pump the sand out into the pool? It is a doughboy filter, so there are no laterals.
Thank you for your help. ;o)
