Pipes below our boiler leaking

ghosthud1

Hi all,

I have had the landlord around and they have spoken to their contact, he can't visit the property until Wednesday.
Can I have your opinion on whether the nut around the pipe needs tightening?

The boiler works but eventually pressure drops off and once the boiler is turned off, it almost drops to 0 pressure.
This seems to occur more overnight when the temperature drops, would that mean that the pipes are shrinking and then expanding causing the leaks to increase?

I have added a video link to view the issue here: https://tiny     url.com/boilerleak

In your shoes, I'd suggest leaving well alone. Yes, if you had a suitable size spanner, nipping up the nut might fix the leak. But you run the risk of twisting the fitting out of place and putting strain on some of the other pipework. In addition, I'd be suspecting the pressure vessel at fault (big red tank, possibly hidden inside the boiler). As this is (I assume) a rental property, you don't want to be messing with stuff and getting the blame for damage and a big bill as a consequence.

Getting an engineer out so quick is pretty good service - I'm waiting for one to visit me, and have been told mid Jan at the earliest.

Yeah, that sounds like the best bet in this situation.

The pipe is still leaking and I don't want it to damage the property, is there any way to stop it in the meantime? I have turned the boiler off, but is there a valve to stop water from going through the system entirely?

Turn off the valve that connects the cold water feed to the input. There are normally two small valves on the filling loop, if this is a combi.

doesn't look like a massive leak, more of a weep. Could it be the expansion vessel that is really at fault?
