bord gais re-pressurizing

tiny timy

Hi, my gas boiler has dropped pressure to 0 and i don't know how to refill it. i have contacted Bord Gais to come service it. Can they refill my boiler for me or do i have to get a plumber also who will top it up. i've looked a few threads about topping up which say about using a hose and topping up from a refill point, but i have nothing like that. Any help would be much appreciated. Thanks

Is it the water pressure in your system that has dropped?

If so there should be a lever valve in your hot press which will get

the pressure back up for you.

Its not a hard thing to refill the system if only a slight fill is required. However if done incorrectly you can overfill it which would have the same consequence as putting to much oil in a car. You will blow something. Usually the safety valve.

However if your confident.

This video explains it quite well. Your filling loop is most likely located in your hot press so you will need someone to watch the gauge on the boiler whilst you slowly open the valve in the hot press.

Thahanks for reply guys, but i do not see this lever valve you are on about. There is one which cuts of the hot water going to rads and thats all. Kinda lost on this one.

Have a look at the heating pipes around your boiler or in the hot pressure there is most likely a braided hose or black knob connection

take a photo and we will advise.

Hi everyone, thanks for all the advise. I went doing a bit of routing and found a straight through joint which turned out to be a non return valve which had ceased up due to lack of use during the summer months. I fixed that and the boiler kicked in straight away but i cannot get my pressure to build up. The water supply in the house is very poor anyway so i wonder if this is the case.?

Its hard to advise. Perhaps a plumber in the house would be batter able to advise.

Hello, I have got the same problem: my gas boiler pressure has dropped to 0 after RGI gas boiler service.
I have contacted Bord Gais to come service again, but have to wait, at the moment no hot water, cold house,
it is not good feeling at the weekend. I tried the advices given here but no joy, any more advices, please

Thanks

Take a photo of the valves in the hot press

Open both black handles on the valves marked as heating.open it until the pressure on the boiler gets to 1bar.
Then shut the valves

I did it, but nothing happens, even there is no water nose
the picture of the 0 pressure is attached.

I found that one of the job the boiler service man done is "System pressure reduced", I can not understand why

Sorry i should have said that on the top valve you will see a slot that is going across,open that with a flat head screw driver.then open both black valves

Should only take maybe 20-30 seconds to get the pressure back up to 1. Are you sure there's water going through that silver flexi-pipe?

Edit: You should hearing water movement going into boiler

It should happen under a minute.
Can you hear water going through the pipe?
If you are comfortable doing so,shut off both black handles and take the flexi off,get a container and open the top black valve again to check if there is water going through it.

After opening up everything as described by rightjob, post another pic of that loop arrangement again.

Dear rightjob and van_beano,

Thank you so much for your help, it works now !
I took out the silver hose, made it clean it by bicycle pump, put it back and turn on.
The water pressure comes up very quickly up to 3 atm, precisely 2.6-2.7
The new picture is attached.

Now I have an issue how to reduce the pressure, or maybe I can use the boiler with the such high pressure.
What is your opinion, please ?

Best regards,

Open a bleed point on the back of a radiator to reduce pressure. Do you know how to bleed a radiator?

Let some water out of one of the rads through the vent screw till the pressure drops to about 1-1.5
