Hello
Sorry if this the wrong place to put this query. After many many years of a freezing cold kitchen I removed the plinth off the front of the kitchen cabinet housing the water supply pipe to find a hole in my floor.
The water supply pipe comes up through the floor and there is a hole the size of a side plate around it. This hole goes right down into the foundations and was presumably left like that after the house was built in the 1990's. As my house has ventilated foundations (via external airbricks) the cold air just gets sucked up the hole and into my kitchen.
My next step is to plug this hole but I am looking for some advice. I can't use expanding foam as the hole seems bottomless (as deep as the foundations) but don't know what else to try. Not sure what the supply pipe is made of - it looks like blue plastic but may be made out of something else.
Can anyone give me some advice?
