Just doing a bit of reading around fitting a Salamander CT50+ shower pump and I notice that the AV couplings are 15mm but documentation talks about 22mm pipework. I know the Surrey flange on the cylinder is 22mm so where do I go down to 15mm? And what size is the feed from from the cold header tank?
Also on the shower side of the pump the diagrams show air vents on both the hot and cold. What do I use for that? Can it be a manual vent for a one off bleed after install or does it need to be automatic?
Thanks for any advice.
