Replacement pump recommendation

[jfb]

To revive a recently deceased thread!

turns out that the system was still causing problems and so  I have had it changed over to a pressurised system.

one question on the install - I had assumed that there would be a tundish by the expansion vessel but there doesn’t appear to be. Is what you can see in the picture a suitable alternative?

Where does the discharge pipe go? There should be some easy means to see if the prv is letting by so either a tundish or a pipe termination outside where the pipe is turned back on itself towards the wall to stop hot, over-pressure release squirting into someone.
