Potterton system - low pressure

[De'Iveote]

Hi There

I have a potterton system boiler. I bled a rad and now have no pressure, can anyone tell me where I attach the filling loop hose

The two pipes under the boiler with the plastic valves on them have been capped are different sizes - is this unusual ?

There is a third capped pipe connected also but this doesnot have a plastic valve - which two do i connect to ?

Your filling loop will be else where, cupboard underneath boiler, cylinder cuboard, under sink or is some of the piping boarded in ?
The 2 valves at each side are heating flow & return. The filling loop requires a cold water pipe to link to a heating pipe.

Thanks - I'll go have a better look

I also found the video below - is it relevant to my system ?

i made that mistake once asked the customer where filling loop was and got a blank look. i explaned what it looked like and still blank look so i got one and fitted it to boiler. a day later i got a phone call saying can i remove that silver pipe thingy we have one of them under the sink

Ok - the plumber was here -

He said there is no filling loop- that the boiler is gravity fed - he will fit one tomorrow - nothing that he can do tonight, so another night of freezing my knackers off.

Seems to me there must be a way of getting water in - or how was it filled when installed ?

Any ideas anyone ?

I did it ...I fixed it ....

I'm warm now...

Thanks to everyone ... what got it in the end was ... a syringe, a piece of hose pipe and a spanner !!

Thank you and good night.
