That's exactly right. BG are not idiots, they know the likely
causes, and indeed we have been working to eliminate them one by
one. The trouble is we are approaching the point that serious damage
will have to be done to the flooring to pin point the leak and
repair it. There is some insurance coverage for tracing and repair
but there will be a lot of disruption to carry out the work.

I exaggerated - it's really about 300mm. We have air bricks in the

spot a pool of water.


It's unlikely to be a pool of water. Certainly not if you are on sandy
soil. Even on clay, depending on what's mixed in, there's a good chance
the water will sink in.

most incentive to solve this issue without damage to the floors.
Something like this, for £20.

I got a usb camera with a 10metre cable from ebay, about a tenner iirc,
it has been very useful and would probably be helpful in the OP case as
it could be taped to a long rod and put though a pretty small hole,
even if it just eliminated some areas it would help a lot.

When this happened to a mates boiler, it was simply the pressure vessel
needed pumping up.

Ah the wonders of the traditional gravity fed top up tank.... If I lose
a bit of water I simply don't give a damn!

You will when the system corrodes away due to fresh O2 entering it all
the time, and dry rot eats your house with the constant supply of water
to feed it.

Easy to do. My combi boiler pumps water downwards, which is not good
for the pumps. Reversing the pump was especially unsuccessful because
of the non-return valve en route. It may have been a bad idea for other
reasons, but I will never know.

By the sounds of it, the OPs system could be losing several litres of
water a day. That means within a couple of months there will be no
active inhibitor left in the system, and it will be continuously
refilled with fresh oxygenated water. That quantity of water is also
possibly being lost the fabric of the building somewhere.

Now what has you pointless comment got to do with any of that?

Gravity fed or sealed system, its problem that needs fixing not

there should be something coming out of one if/when the boiler
is running.

There has to be water coming out of the condense pipe when the
boiler is running.
Are you sure that it is not blocked or something?

Some twit could have installed it outside where it freezes.

It's not yet cold enough for that.

It is here, and has been for the last 3 nights.

It takes a lot to freeze up a condense pipe.

If something is heated UP, it should be frozen DOWN :-)


FFS!
I'm sure that the OP will take note of your helpful comment.

Well you cool down.....

Yes, got that Harry, in this case neither seems to be leaking water.

We had that years ago when the condensate pipe froze, the water
backed up into the combustion 'chamber' and killed the burner. Not
happening here. Anyway these litres of refill water have to be going
somewhere and the boiler seems dry.
The search continues.

Your neighbour tapped into one of the radiator pipes for free heating, and THEY have a leak somewhere :-)

Yes okay and all of that.
But, have you even looked at the condense pipe?
There Really should be water coming out of it.
If you have not taken the time to look, then never mind.

Modern fancy rubbish, bound to go wrong. My boiler does not have the need to condense. Why do people spend £1000s on a fancy boiler to save them £100s on gas?

Because they don't have a choice?

Nobody forces you to buy a new boiler.

That's exactly right. BG are not idiots, they know the likely
causes, and indeed we have been working to eliminate them one by
one. The trouble is we are approaching the point that serious damage
will have to be done to the flooring to pin point the leak and
repair it. There is some insurance coverage for tracing and repair
but there will be a lot of disruption to carry out the work.

I suppose it would not be possible to bypass the suspect pipes by a
separate, but permanent and cosmetically acceptable, route? Say via a
different room, or a ceiling?

As an update to the story - using a leak tracing company we found
the leak was in a radiator feed pipe in the bathroom. Fortunately
plain sheet vinyl flooring there so simple to get to the pipes. The
feed included a push-fit joint situated under one of the walls.
Using the company's camera you could see the drips from the joint!
They have a useful acoustic detector thing too - impressive
swooshing noises on pipes near the fault.

Many thanks for everyone's thoughts, and the many helpful
suggestions that helped our thinking on possible ways forward.

Plumbing now in progress to repair fault.
