Geez, being a partimer,suggest looking to see if any water in the f&e tank Try opening the system drain cock, see if any water flows out. Could be the feed blocked from the f&e tank. Dont run the pump dry or you'll nacker it

might take u a bit longer try tinning the pipe end an old fashioned way of making sure 2 surfaces are going to stick

just a quick check White = heating on from room stat Grey = HW satisfied fed back to clock HW off terminal Orange = HW on & boiler/pump switched live from cylinder stat blue = neutral green/yellow earth wot code is on the plate zvd or zvm sure its a mid & not a diverter

Thanks for all that helped in my last thread, but I think now my prob is cavitation. Being a fully pumped open vent sys with 2 zone valves . The distance from the boiler to the pump is approx 30ft horizontally piped in 22mm. The noise in the pump happens intermittently and just sounds like a...

Thanks, so my set up wouldn't be the cause of air in the system? If I moved the CW feed to the pump line would it def eliminate any chance of sucking air in?

Thas my set up kevplumb, should the pumptee and the CW feed be closer

no it was gravity to HW cyl and pumped to rads. Moved boiler from kitchen to garage

think u got me wrong, cant find a way of posting diagram yet try tonite Imagine the vent pipe in airing cupboard, i've teed of this for the pump 4ft above i teed off the vent pipe for the cold water feed in
