lol Ian it has only been used once and properly flushed out. An inhibiter has always been added after any work carried out.stop constantly putting x800 in your system it will kill your pump

What I have noticed is the motorised valve when attached sits loose like and wondering if that would affect the pin?
New to this, looking for some advice...
Combi boiler radiators (7 in total, upstairs/downstairs house) were not heating up some not at all. System always topped up with "inhibiter". Hot water great. So
- all radiators removed and flushed clean. (Some black water, to grey to clear)
- pipework at each radiator point the same. (same)
- new lock shield valves and tvr's fitted where need be.
- New Grundfos Pump head fitted.
- Domestic Heat Exchanger removed and cleaned with Sentinel 800.
- Auto Air vent cleaned as it had white deposits at the vent.
- Additional Sentinel 800 added to system. System flushed and drained again.
- Re-filled downstairs first then upstairs. Inhibiter added. Radiators bled of air. same with Pump. Refilled to 1.3 pressure. Before system switched back on.
- Boiler holds its pressure at 1.3. Bypass gate valve very slightly open. Feed pipe gets very hot and return pipe gets hot however clear difference in temperature to feed pipe.
- Thermostat works in that the gas burner engages when turned up, same for hot water.
- Main burner looks clean when fired up.
However only one radiator closes to boiler upstairs goes to temperature and a little in the next one in the upstairs hall..the other 5 nothing. LSV set at half up stairs and one downstairs. Radiators bled again till water drips out. When heating on I still get hot water. I have left the boiler on timer and the pump at setting 2 to see if this make a difference so far no change.
I have had a professional look at this and was not impressed with bill and he only changed the filling loop tap as he advised had a leak. He advised none of the above though stated pump perhaps needed replacing. The boiler is over 8 years old however would like to repair than replace if possible.
Any advice most welcome. Thanks.
replaced the domestic heat ex-changer unit
Aye stop fecking around and employ someone that knows what they are doingAny tips on the best way to balance radiators would be welcome. Thank
