Old radiator pipes - avoiding holes in new flooring

[Sorbustree123]

Had an old radiator removed and connecting pipes (that come up through the floorboards by a couple of cms) capped off. There is some flex in these pipes and so I'm wondering if it will be okay to simple dip them below the sub-floor, to hide them away and avoid the need for holes through the new flooring when it goes down, as we don't intend to reintroduce a radiator in this area. Thanks in advance.

Giving this a bump in the hope that @PigletJohn might see it, and thanks in advance for any words if wisdom you're able to share.

We had similar and they were able to cut it and push down level with the board but not completely below. That may be OK for you if the existing flooring can sit on top.

That said, it'd be a pretty quick job for a plumber to lift that board, cut it and cap below the surface, then put it back down. Less than an hour.

yes, better to have it cut and capped below the floor, but preferably take up the whole run, or there will be a pipe full of water under the floor, with no sign of its existence, waiting for someone to put a nail or screw though it.

you will probably be able to see the signs where the previous plumber took up the boards to install it.

Thank you both so much for your advice. Would the central heating system need to be drained down in order for these pipes to be capped off below the floor?

not neccessarily.

Depending on where it is (top floor vs ground floor) they might do, but since it's a quick job it'd probably be easier for them to just use pipe freezers. (So long as they remember to turn off the boiler so it's freezing cold water not hot!)

if it's a sealed system (fairly modern, with a pressure gauge on the boiler) you can cut any one pipe, and only enough water will come out to relieve the pressure.

If it has a feed and expansion tank in the loft, they can bung the pipes to get a similar effect.

If it's in the ground floor, many plumbers don't care about a bit of spilled water and will expect to get the cap on within 5 seconds or so.

Excellent, thank you so much @PigletJohn
