I posted a while ago about a leaking blow off valve (Temperature / Pressure) on my hot water
tank. It still has been leaking and the red knob finally corroded off.
The boat is a UK built Southerly 110.
It seems like I need a new valve. BUT, before I source the (probably Italian part) It occurred to me that maybe I'm leaking because I'm over pressurizing my tank.
The Shurflo pump pressurizes to 55 psi and some of the references
I've seen to European blow off valves reference 2.5 bars. About 36 psi.
There are no markings on the hot water
tank I can find.
Does anyone know if there are pressure standards for European hot water tanks
on boats? And what those standards might be?
