What procedure do people use to de-solder joints where there is still some water left inside the pipes? Is there a way to remove the water after pipes have been drained as well as possible? Can the water be sucked out using a hand pump? Could this even work and if so how to do it? Or do plumbers just cut the damn pipes and deal with water flow as best as possible, letting most of it soak into the plasterboard? Any ideas are welcome. There are many horizontal pipes where some water remains. I have attempted to de-solder joints but it has taken a very long time to get them apart and I think it i

Thanks for your reply, the pipes all had to be re-done due to the change in radiator size and width, so I have fed to the TRV side, which is on the right, because it has the best airflow to the TRV.

I am replacing a bedroom single panel radiator with a double panel double convector because the previous rad was not sufficient. I also want to fit a TRV, there was none fitted before and with the larger radiator it is now needed. Lots unexpected problems have been delaying this, such as plaster falling off a wall and a wall practically unsupported on floorboards due to cement breaking out over the last 46 years. The house is very cold so I need to get it finished quickly. The left side of the rad is on a wall less than 3 feet from another wall at right angles so it is very close to a corner a

You can get radiator tails with valves in them with small screws on them to turn off the flow. You change the Radiator tails on both sides when doing it. Then you can turn off the radiator valve and lockshield and turn off the valve on the tails and then undo the union nuts and remove the radiator. Help may be required as the radiator will be full of water and could be very heavy. Then the wall can be re-decorated fully and then replaced without having to drain the heating system or lose any water/protector. Otherwise you can close the radiator valves on both sides and put a small pan undernea
