What is the purpose of this vent/pipe ?

[garash]

We appear to have moisture/mould along some of our skirting in a bedroom . The property is a Bungalow so we are ground level and the bedroom runs along the outside wall where you see this pipe. As the ground has been dug up previously to insert this pipe I suspect there could be an ongoing problem. There is an inspection cover a few feet away from this. What would be the reason for the insertion of such a pipe?

the pipe looks like a rodding point or a redundant drain.
The mould if it was winter I would say just condensation from insufficient ventilation, but since it's summer it could be a leak or other water escaping. If you poke the skirting with a screwdriver is it soft all the way through? Is the floor timber and how about that? Also can you roll back the carpet etc and look underneath?

The [ex] hole in the wall gives it away.

One time toilet at the other side of that wall maybe?

Thank you. We have been here 2 yrs the skirtings are all new and are not soft (yet?). The floor base is concrete. I will endeavour to make further enquiries based on your info. Thank you

Yes the Bathroom/Toilet is the other side as is the Kitchen.

Yes the Bathroom/Toilet is the other side as is the Kitchen.

So the toilet position has been revised, the hole in the wall repaired and just that stub of pipe left sticking up?

You could lift the inspection cover, see what goes into it and if there is only that stub of pipe entering it, you could cement the pipe entry up and cut stub level and fill that with cement..

Have to wonder if as historically, there was a WC the other side of the wall, the supply to that is still present, and is leaking.

I think it unlikely that 110mm pipe is causing your issue, I'd leave well alone unless it's a trip hazard.

I would also suggest it being unlikely to be the cause of the damp issue. More likely is breakdown of the DPC in that area, or soil level above the DPC. I was just suggesting that if the pipe has no purpose, it could so easily be removed.

In fairness, DPC is visible in the pic, so bridging doesn't appear to be an issue, breakdown may be, but I'd be looking internally first.
