put the pump between speeds instead of keep switching it on/off at the power.

ok thanks so do you mean runing it on 1 for abit then 3 then 2 and see how it does?
say the pipework around boiler, pump is airlocked after refill run it on 3
then move switch to between 2/3 and pump stops then to 3 again.
but move the speed knob every few secs or so so it rocks the water
and you'll find it'll shift most airlocks.

one more question I'm putting a new radiator in up stairs, to do this Am I best of draining the whole system, or just the up stairs rads. Which way wil best avoid airlocks when filling back up.
are you just changing a rad or a complete new rad/pipework etc ?
I'm changing the radiator in my bathroom to a towel radiator.
so you'll be altering pipes ?
then i would drain to below the upstairs rads/pipework.

yes am altering the pipework, would you recommend just draing the upstairs rads and pipework. Not the whole of the system. Thanks for ur help.
yes that'll be fine
will it be less likely to airlock when filling back up if done this way as oppose to a total drain down?
depends on the system etc all are different some are prone to airlocks some aren't.
ok thanks for your help
