I do that on a boiler change, as I change components also. Good idea to so more often though to make sure it's correct.

OK have changed the 3 port this morning. Its now doing what it should, on and off for each demand.

Rads getting nice and hot.

HW getting through coil OK. Didn't get any water from the coil when disconnected and capped.

Hoping thats solved it.

Will find out today.

Don't know what else it could be if not.

The ball valve that time changed on the F and E a few weeks ago has been getting sprayed with water from vent at some point as theres dirty ch water marks all over the shiny brass.
