Leak Advice

dublin runner

Hey all, looking for some guidance. We have had a number of people out to look but wanted to see if anyone could possibly share some light on the issue.

Long story short, the leak was discovered whilst putting down new floor. The wet area is limited to the corner of the extension, where the heating (oil boiler from outside) meets the slab.

We just moved in and the extension looks like a bit (alot) like a DIY effort.

No water ingress noticed until the floor came up.

The gutters/roof have both been eliminated. The two favourites are the pipes and the the lack of proper waterproof measures in the slab.

Is the heating system sealed or pressurised?

Is the heating system loosing pressure? What does the pressure guage at the boiler read?

I would guess your going to have to go digging in that corner.

Are both them pictures of the same corner of the room? or is one picture outside? the pipes seem to be coming in very high above the floor level?

What is the level of the ground outside?

There is no pressure gauge on the system.

The picture are of same corner - one with boarding, one without (bare concrete slab)

The extension is approximately 12in above the level of garden.

I guess we need to dig the area. We have now advised several differing ways of addressing. The system is working but the radiator beside said leak is not working as should be, with a lack of heat output found.

The area outside the extension - where the leak is - is the wettest part of the small garden. That probably supports a leak in the pipe? It is not considerable, just noticeable in a small way.

If the valves are ok on the radiator beside the leak and there isn't air in it, your going to have to dig up the pipes now at this stage.

You will want to dig it up anyway, so you can lower the level of the pipes and hide them under the floor. Its only a little bit of concrete anyway.

I don't fully understand your post above, are you saying there is also a leak outside too?

Do you know how the system is filled?

You might be just better cutting the concrete outside and bringing in a complete new run from the boiler to inside the house.

Thanks for reply.

There seems to be water pooling slightly at the corner. This could be of course due to the uneven nature of said area.

Agreed - digging in the new year

if the job is as bad as it looks, the pipes won't be that far down. Don't worry about breaking up some concrete, it is very easy to put it down afterwards, especially in a corner like that. Lump hammer and chssel will probably take up most of it. Obviously go easy around the pipes till ya know where everything is located in the slab.

Yeah, a shocking job alright!

Thanks for the advice.
