Cold feed blocked by the sound of it.From the small exp tank(loft?) follow the 15mm pipe from where it leaves the tank and where it joins the system pipework is where you will find your blockage.That's assuming the F/E tank has water in it.What steps did you take to turn the feed to the system off prior to draining?

the cold feed pipe from the header tank to where it connects into the system will be blocked with magentite. You need to now bung the header tank, cut the pipe just before it connects to the system, whack a screw driver in and clear out as much as possible each way. Connect back up with a straight comp fitting for next time.

Ya know something? This is exactly the same fault the guy with the funny user name had. Both had the same boiler, same fault and both from Staffordshire. If it looks like a horse, runs like a horse and farts like a horse - you can bet your bottom dollar it's the same animal.

i have just pushed about 3 metres of cable down the bottom pipe of the small tank in the loft the boilefr started up for a min then went of the pipe comes down the wall in my sons room then under the floor boards then to the boiler in the lounge .

when i drained the system i turned the stop cock to the house of the put the hot and cold taps on . then opened the drain plug at the front of the house .thanks a lot for your help so far but still not working the rads down stairs have water and i have bleed them but nothing upstairs.

Ya know something Joe? Its entirely different.

Oh no it's not - it's just the flippin same.

Sonicuk,The only way you are going to sort this is to find the cold feed connection where it joins the system wherever it may be and unblock it.If the connection has been made directly onto the boiler(as sometimes happens)then you need the firefront removed and for that a registered engineer.I hope that the connection is elsewhere.Cold feed connections are usually to be found near hw cylinders on pipework in airing cupboards.

Oh no it's not - it's just the flippin same.

Joe, read both posts and try to spot the difference,or is that asking too much?

if i follow the pipe to the hot water tant it tees of one part to the tank the other part under the floor boars . would this be the point it would be blocked at thanks a lot
from the tank in the loft to the tee piece in the airing cupdoard is 15 mm the it goes to two 22mm

 

[45yearsagasman]

Yes I think you may have found it on the return pipe from the bottom of the hot water cylinder. That is a very common place to connect the cold feed.

Oh yeah - your wrong diagnosis. But look past - and they are the same.

 

[sonicuk]

[45yearsagasman]
