pipes hard up against floorboards

[flutterbye]

Hi

I wonder if anyone can help with this? In a bedroom in our house a persistent clicking noise can heard. It lasts for at least 30-60 minutes after turning off the heating system.

So I lifted a floorboard and was almost lucky not to have cut a pipe with my circular saw due to the pipe the pressed hard up against the floorboard. Unfortunately, the floorboard runs perpendicular to the pipe so can't easily track it as it makes its way to the other side of the radiator. Of course this means the joists are parallel to the pipe.

Anyway, presumably its not great practice to run pipes hard up against the floorboard? And presumably that is what is making the clicking noise?

I did try a quick fix of putting a sliver of rockwool between it and the board but it didn't help. Is the only way to sort this out to remove dozens of other floorboards, drain the system and somehow redo the pipework in that room to have it lowered? How should a pipe run under the floor in such circumstances? Clipped to a single joist halfway between ceiling below and floorboard maybe?

Thanks in advance for any replies.

cut either side of the pipe notch. then take a sliver from under the pipe, be careful tho.

Thanks but the pipes run parallel to the joists so there is no notch in the joist to cut!
They run parallel and hard up against the underside of the floorboards.

Well something must be holding the pipes up if the joists aren't, pipe clips?

Its hard to see without taking a lot more floorboards up but couldn't it be a combination of where the pipe enters the room under the wall and also where the pipes connect to the rad tails ?

Well yes, but it must be possible to move, flex the pipes a few mm and re clip to miss the floor boards.

I would but the pipe doesn't run close to the joist - parallel but in between them.

if its inbetween the joists but too high and hitting the floorboard it will need to be dropped cant be too difficult if its not clipped to the joist, force it down and slide thin polystyrene, rubber or something between the pipe and board
