Pause Before Water Comes Out Of Tap

Its the calorifier PRV, mine is like that so I do not waste water if it ever has to open. On this boat the accumulator/expansion vessel looks a bit small to me for a decent sized calorifier so it may have to open regularly. Locating it there does mean you may get hot water running back up the cold line but in my case the taps are so far away it makes no difference (apart from a rather theoretical risk associated with leigionella) and as calorifiers tend to be a but difficult to easily access it gives easier access to twist the knob if required.

Thanks Tony. I thought it looked like a PRV, but am more used to seeing them installed on the calorifier. Learnt something today!

That position only works if there is no non-return valve on the cold inlet to the calorifier.

 

On my boat the pump, remote pressure switch, strainer & PRV are all mounted on a board so if so moved I can take the whole lot home in the winter.

Very interesting comments. It's fair to say I didn't understand most of it! I've got a lot to learn
