Dripping in Wall cavity after boiler service

[Deleted member 103127]

Hi, I'm after some advice if possible please! We had our Combi boiler (in kitchen) serviced for it's 3rd year last week & since then we've noticed a fast dripping sound in our sitting room wall cavity when the heating is on! It slows to 1 drip per 40 secs once heating turns off! Our house was extended 3-4 yrs ago & the radiator was removed from the wall in question & attached to the opposite side of the same wall into our new kitchen so there shouldn't be any spare pipes to be dripping! After the service we noticed the temperature had been turned up to full on both the radiator & water dial on the baxi boiler, could this have anything to do with it? All radiators are working as normal. Any help would be greatly appreciated, thanks Lindsay.

I’d suspect it’s nothing to do with the service just an unfortunate coincidence. Just because someone has worked in your house does not automatically mean that they’re to blame if something is leaking. Maybe post some pics and we can offer ideas

There is nothing to take photos of as I said the drip is in the cavity wall so we can hear it! I wasn't blaming anyone either I'm just asking is it normal for the dials to be turned up & left at full during & after a service as we never turn them up due to having young children who could get scolded if too hot!

The engineer should really have asked but may also have set your boiler to a more efficient set up. You have to forgive me, when people say we had someone in and ever since xyz has happened often they are looking for a way to blame the previous contractor. Are you losing pressure on your boiler

Is it definitely a leak, could it be pipe 'clicking' while it's expanding with heat?
Is there any signs of damp?

The dials may have been set to max to test the boiler in service mode

No but the contractor did ask if we've ever had to reset the pressure which my husband told him no! Everything seems fine it's just the dripping noise & trying to work out what it is as it's between our old external wall so will need bricks removed to access & no doubt insurance company will ask if the service has had anything to do with it so at least I can give some sensible answers & not let them pass the buck! Thanks for your advice.

If you’re not losing pressure it won’t be a central heating leak

No signs as yet but it's only been dripping for about a week & the wall was our old external wall so I'm assuming the damp proof layer is stopping it showing up to now! We've never heard any noise previously & we are in the sitting room every evening for hours with the kids.

As I said if it’s a leak on central heating you’d be topping pressure up

Right that's great thanks I'll keep an eye on it though for the next few days.

expansion and contraction of pipes touching something will sound like dripping

Thanks hopefully that's what it is
