Removal of Radiator

[coolwaterpaul]

Could you help me, a friend of mine has asked me to remove a radiator completely, from the front room and he would like the 2 pipes which are vertical which were attached to the radiator to be hidden below the concrete.
Could i cap off both pipes or would i have to connect both pipes together to continue the flow? ?
Could you help?

What would you advise?

Many thanks.

you could cap them as it is only a branch off the flow and return its better to cap them as close as you can to the pipe they are fed from try lifting the floor boards upstairs and follow the pipes. when you say under the concreate do you mean the plaster on the wall if so you can bury them under that but you may have to take away some of the brick to get the plaster flush with the rest of the wall you should also cover the pipes with anti corrosion tape.

Thanks for the reply, so i can cap both pipes seperately flush with the concrete, would i not have to join both pipes together to carry on the flow?

If the pipes are all in the concrete I normally break out some of the concrete and cut the pipes below the level of the floor, cap it and make good. If you can trace the pipes back to ceiling void you can cut and cap there. But make sure the pipes only feed that 1 radiator.

thanks for the reply, how would i check if the pipes only feed that 1 radiator?

[SimonG]

Find the pipes in the ceiling void, close the valves on the rad and then switch on the heating. Check to see if the pipes in the ceiling heat up. Chances are that if all the ground floor pipes are in the concrete then the feed will probably go to more than one rad.

Many thanks for the reply, i will join the 2 pipes with a longer piece and connect to carry on the flow, would that be advisable?

[SimonG]

It depends where abouts you are going to connect them. If it's down in the concrete I would just cap off. If it's up in the ceiling you still need to check that they only feed that 1 rad, but again just capping is ok.

Cheers again simon G, i have spoken to my mate who i am doing the rad for, i have said to turn the 2 pipes off which are connecting the rad, turn the central heating on, if all the other rads heat up, then that should answer the question! so if all the other rads heat up then i can remove the rad and cap both pipes, is this correct?
Can i use compression fit to cap off both pipes below concrete? any advice?

[SimonG]

Compression is fine.
