Helpppp!!! Our Worcester boiler has just started leaking out of the bottom!!!

[Mueslibox]

Out born boiler is weirdly in the attic conversion where we sleep and my husband just woke up to water dripping/pouring out of the bottom of it, enough to already have gone through the ceiling to landing.

We’ve turned it off and trying to contact emergency repair people but in Northern Ireland and it’s a flipping bank holiday.

It’s turned off, but it’s not going to explode, is it???

I have no idea what ‘born boiler’ is?

No it won't explode

Turn it off and isolate any water supply to it

Our did the same but luckily it was in the garage.

New boiler needed probably!

It’s quite a new Worcester boiler is the thing, I’m really surprised, but then the whole installation of it is a bit odd, why they’d put it in the attic I’ve no idea...

Sounds to me like the boiler pressure had got high, had somebody been topping up the pressure and left the valve open ? I'm no boiler expert though.

Hi, we had something like this recently with a 4 year old Worcester boiler. Water was pouring out of the bottom of the boiler casing. It was a faulty air pressure valve. It is designed to self seal to let air out of the system but keep the water in, but ours wasn’t sealing properly so was letting water out as well. The emergency gas engineer sorted it out by shutting the valve completely (so no air or water could escape) until he could return with a replacement valve. In our case it seems some dirt in the system had stuck in the air pressure valve. I hope you get it sorted.

I wouldn’t sleep (or let anyone else sleep) in the same room as a gas boiler. Have you got a CO detector?

I just had this with a Worcester boiler too! It was a tiny little hole in a plastic part in the boiler - the engineer called it pinholing and said it did happen with Worcesters. He just had to replace the part.

Others are right - just turn the water off.

Im assuming you don’t need the heating on? You’ll need to boil the kettle a lot!

If it is still under warranty you can phone Worcester Bosch and they will come out and fix for free

Some interesting answers but everyone is generally right that it will likely just be a small thing, and turn off the water.
If you can take a photo of the boiler underneath there should be a bunch of valves you can turn off there, to avoid losing your whole water supply.
If the water is from the radiator circuit (may be discoloured) then turning off the water won't help but it won't leak much. If it's fresh water it's from the dhw side and will stop when you turn off the water.
Don't worry about carbon monoxide from a leak of water, they are completely different sides of the boiler.

We had this recently with our Worcester boiler, which is only about 4 or 5 years old and still under extended warranty. Luckily ours is in the utility room, so inconvenient but not disaster. The plumber who fixed it said Worcester’s are known for this issue of faulty valve. Has put me off buying Worcester again. I hope you can get it sorted soon.

rain had it - pinhole leak. Not possible to isolate water so boiler turned off and complex water catching system in place. Super lovely engineer came out and is trying to get the part on a gorgeous bank holiday in NI (so we don’t get that many nice days!!!). Because the boiler’s off it’s a heavy drip rather than a torrent but still filling a large bucket every few hours. Hopefully fixed tomorrow.

maple I agree, it’s in its own little room though and I have TWO carbon monoxide monitors /alarms. Going to try and get it moved this summer.

Modern gas boilers are room sealed. There should therefore be no access from the combustion chamber into the living space. Also natural gas i,e methane ,when burned does not produce appreciable amounts of co.

CH4 + "2O2=CO2+2H2O

Limpo that applies to a well maintained boiler in good condition but a faulty boiler can produce carbon monoxide. That's why boiler technicians carry flue gas analysers

Yes indeed thats true. Modern boilers have many safeguards to protect end users. Sometimes the attentions of a gas Engineer can actually bring about a dangerous circumstance due to act,omission or lack of training. CO can also be produced by mobile calor gas heaters, open fires, log burners ,poorly maintained gas cookers and gas fires etc..
