Water on multiport valve

Is it normal for water to slowly accumulate on top of the multiport valve or do I need to tighten it or replace a gasket?
The water first fills up the grooves and then the top but it takes about a day to start spilling over to the ground.

You may have a worn or dry handle shaft stem O-ring. You can Google the parts for that valve to confirm what O-ring it uses. Maybe open first to inspect and apply some silicone lube to see if that helps. If you do order an O-ring, also look for the tension spring underneath. It may be worn and not applying enough pressure to keep everything tight as well. Just replace both at the same time.
