Installed new pump, no pressure in groups
Had a leaky rotary pump which I replaced it today. The boilers fills and the steam-wand and tap works great but I'm yielding no pressure in the group heads. Just a bit of steam out of each. Can anyone help out?
I've fiddled with the OPV in the past and had nothing but trouble since. Could that be it?
If the boilers are filling you would expect for at least some water to come out of the group.
The pressure adjustment on a rotary pump is simple, give it a tweak and see if it makes any difference.
Forgot to mention the OPV in a rotary pump is normally set at 12 bar as a safety pressure bleed incase your bypass in the pump head jams and the pressure rockets.
The adjustment for pump pressure is a screw / bolt on the pump head itself (with a lock nut).
