Like others, I ran a hose from the pressure value to the engine bilge so it would be easier to monitor and mop up.  We also turn the water pump off when running the engine and relieve some pressure from the system via the sink water tap.

I fitted one of the standard non-return valves from the chandlers into the cold water system and it leaked at an enormous rate.  I think that they are designed just for maintaining the fluid in the suction pipework of a pump or to prevent back-flow in a discharge pipe and not for use in a pressurised water system. 

Isotemp stress that the calorifiers must be mounted horizontally and not vertically and so I wondering where that means there will actually be an air-space at the top of the tank which could absorb some of the expansion.

I believe they want it mounted horizontally to provide a means of draining the tank.

I also put a hose on the overpressure valve and drilled a whole into the aft compartment of the life raft and let it drain there. So no need to remember anything, I never had any water below the boiler..
