I have noticed that my sand filter is leaking from under the multiport and under the band where it connects to the tank. It is only leaking on one side. Is there an easy fix for this? It is a not really a leak - more like a slow seep. I haven't noticed any pressure changes. There is also no water leaking out of the backwash hose so I think the multiport is fine.
The PB changed the sand in the filter after the replaster. I don't know if that had anything to do with it.
