Old Central Heating Pipes causing damp

Jun 03, 2007 9 Replies

We recently moved into a early 1960s build house, where the orginal heatng system has been replaced. However the original pipes have been cut off and it would seem still contain water and this has effected the carpet underlay in the region close to the pipe cut off in certain rooms .



Does any one have experience of this problem and what would be the recommended solution ?



Thanks in advance.


Why can't the pipes be drained off? Do you mean that the original pipes have been cut flush with the floor? What type of floor is it, concrete or wooden floorboards?

Yes the old pipes have been cut flush with the floor and in some cases the ends bent over. Its a concrete floor that the pipes are buried under.

Expose the pipe ends and open as necessary. Get some plastic tube and suck the contents out as best you can (don't swallow any of the crud though!!) Do this repeatedly and from different locations to ensure you get the low point. Blow hot air down the pipes to dry thoroughly. Re-seal pipes.

I would find a pond/aquarium pump or something similar to do this. I know there will be rude comments but I would not even want the contents in my mouth never mind swallow.

The pipes were obivously not sealed.

Thanks all for your responses. What is the best way to seal them to prevent the problem in the future ?

Buy a bag of mortar mix from a shed and fill each pipe to the top with the dry mix. Water in the pipe will be drawn into the powder and fill it at the same time.

How?

You cannot be serious?

Once there is no water in them then there is no need to seal the pipes.

I used a "aquavac" cleaner with an attachment made from a demijohn bung in an old vacuum cleaner pipe to convert from the cleaner hose to some clear 8mm PVC pipe. The amount of water that came out was amazing and I had to empty the cleaner several times. I will give it a week and try again to make sure its dry.
