Boiler wont ignite pressure on 1.5 (moved from Information).

[may hawkins]

I've taken an old radiater of the landing.didnt want one there. so cut pipes and Capped them...black water came out of the radiator pipes,about 5 litres.all mains was switched off.now the boiler wont light it sounds like it's trying to fill the pressure bar is on 1.5

Did you fill it back up again once drained? Maybe the pressure gauge is giving a false reading if system is dirty.

Perhaps the rads were series connected together, and therefore there is now a break in the circuit? The boiler doesn't have control of filling the radiators, you have to do that yourself.

When I switch the boiler on it mkes a gushing sound then stops tries to fir up but don't.on checking the radiater after there's water in all of them.there's a blk tap on a flexible pipe on boiler when on switch it on it leaks..did wonder whether should cap or put a connecter on there so pipes join??

The picture of put up is how pipes are at the moment

Would need to see a picture of the filling loop

What is a filling loop?? the picture I've posted is the white stops I've put on after taking off radiator. These pipes lead to pipes in spare room were one piperson leads to radiater in there the others goes down to kitchen. Wondered if the one on the left needs to be attached to the other...

After draining your system to do the alterations did you re fill the system via a filling loop?
If not you need to find it, usually under boiler

There a silver flexible with a tap on it.I turned this on then checked radiator theres water running through them.the pressure valve is on 1.5..

 

[may hawkins]

So turned it off.but when tried again water is coming from the connecter only little drips

Sounds likes you still have a lot of air in the system keep bleeding the rads get as much air out as you can.

 

[may hawkins]

Do 8 have to refill after bleeding can i use the tap outside to bleed them all or shall I do one at a time..

 

[nortonj]

Bleed all rads via bleed tap on side or back of each rad. Start downstairs work your way up. Keep topping the pressure up when it falls
