Answer 3

I'm thinking that your water pump is failing and must be replaced.  If it'sa couple years old it can "take a set" and begin to pump less water.  Because of the sirculation pattern this offten turns up on the port elbow.  Hopefully on real damage was done, but have the impeller changed when you get the bellows repaired.  Good Luck!
