water dripping from the bottom of my gas boiler

worried_jim

I have just discovered water dripping from the bottom of my gas boiler.

It is a vokera excell 80sp.

The water is dripping from the bottom of two pipes-



It's dripping from the both the "silver valves", but predominantly from the pipe on the left of the pic, partially obscured by the pipe in front of it.

The heating is on and working and hot water comes out the tap as per usual. Any ideas?

Is it leaking from connection going into boiler or the one pointing to the floor? Perhaps all is required is correct size spanner or adjustable spanner required to tighten back up.

It's not from the connection it self, but from above in the boiler- it's just collecting down the pipe to the angled join and then dripping onto the floor (bowl now).

Ok you need to trace leak,


I am not expert, Sure someone will be along here shortly though.


But it could be Auto air vent valve. or the pressure relief valve.


But try to trace first

Are you losing pressure on dial on RHS?

Yes it is.

IMHO it's a 'get the man in' job then . Leaks from inside the boiler casing could have many causes, but a failing expansion tank would certainly cause the pressure to drop.

YOu could keep the pressure in the working zone by topping up using the filling loop and hope to nurse it through until after the holidays.

I've just turned it off as the dripping in increasing. Will turn it on for hot water, fortunately it's not cold here and I have the fire in the lounge and a little portable oil filled radiator.

I thought I would give an update to how this has panned out.

I tried to contact a plumber that I have used to service the boiler but I couldn't get hold of him so I trawled through the local advertiser and then cross referenced the ads with http://www.checkatrade.com/ to find someone local with good reviews.

On Monday, Michael turned up ( with a new apprentice on his first day)on time at 08:30 to have a look and diagnosed a new pressure relief valve.

We agreed on a price and Micheal returned on Thursday at 09:00 and started on the job. He used two different chemicals in the system, one to clear out the limescale and another called "shhh" to help the boiler run quietly.

Whilst replacing the valve he discovered some other leaks and tightened up the appropriate taps and valves. After about two hours we were all done and the boiler was running perfectly and very quietly.

£130 all in. I am so very happy with the work done, price and his workmanship- he was really passionate about boilers and we had a great chat about new technology and how his job was changing and evolving. I am relived to find a new plumber and will definitely recommend him and use again.
