Potterton Puma 80 pilot light problem

[andy_c_help_me]

Hello,

I am having a new bathroom fitted and the builders removed the radiator in there and since then the pilot light will not stay on?

It re - lights but goes out after a few minutes once the water of CH has been switched on? Also hot water pressure is really low.

Could it be air in the system from when they removed the rads?

If so how do I get it out?

repressurize heating , bleed the radiators ,also losen the big srew on the pump till a little water comes out , repressurize the system ,(try that it will get the air out but might not solve it) let me know

And check that the automatic air vent on the boiler is actually open - black screw cap should be loose (top left, on top of casing).

If your water pressure is low then the flow rate will be low....and so....the boiler won't fire up. Remove the flow restrictor in the water flow pipe

you want to rephrase that cos it sounds like b*lls mate

Another patient and yes it's 22:50 on a Saturday night and eveyone but my good lady and I are out enjoying a bevvy or three -

So the story starts - I reluctantly replaced a rad in my bathroom.
I thought I'd be clever and bleed the rads from the closest to the boiler (Potterton) anyway, after filling a bucket or so I replaced the rad with a ladder type rad. It looks great although there's no water in it !!

I've closed all valves on all rads and opened the screw on the pump, I can see it churning away but no water in sight... When I turn on the central heating / water heater the pump starts and the boiler fires up...
A few minutes later the boiler switches off again.

I know I've drained the water that was in the boiler and there's an airblock of some sort but how can I get water into the system in this state?
I was confused until I read your posts and now I'm alittle wiser but I'm at a loss as how to get water into the system?

Please help before I'm nagged to death ...

A: I'd love to stop messing with the system and call a real plumber but - and I mean this with the greatest of respect to all plumbers - I don't want to get ripped off for a simple task like a filling loop that first Plumber wouldn't find or know about - however baffle me with ideas that I need my pipe work ripped out and replaced????

Once bitten...

B: Looked for a filling loop although can't find anything of that description in the house, I'd take a wild stab that this is integral to the boiler?
Shut off all rads, all the ground floor rads are full and only have (cold) water and the upstairs rads are empty and stone cold !

Can I just fill one rad with water until it's full (hopefully the water will pass round the system and the air can be bled? If all the ground floor rads are fine and the boiler has no water - I need to find a filling loop of sorts.
It's 02:02, I can't keep my eyes open for much longer ...

Would be gratful if anyone be able to recommend the services of a plumber in the South West (Home Counties)
