Water Tank

[Paulam]

Hello re 1987 Catalina 36. My main water tank develops pressure when filling. Vent line is clear. Any ideas?

What happens when you open the inspection port while filling?

If your water pressure pump is off, then your filling water at a rate greater than the vent line can manage. You say the vent line is clear. Where does the vent line run?

• Is it kinked so that it shuts down the air escaping from the tank?
• Does the vent line vent into the open fill fitting? Are you putting water into the tank and the vent line at the same time?

Care to tell us exactly what evidence leads you to believe your vent line is clear ?
