Removing the old radiator

One of the great deterrents to anyone wanting to remove a radiator is the prospect of having to drain the whole system. However, this won’t be necessary provided the radiator to be replaced has a valve at both the hot water inlet and the outlet. Once these are closed. you’ll be able to keep virtually all the system’s water isolated in other parts.

At the inlet end you’re likely to find the hand-valve which is the control by which you open and close the radiator. At the outlet end you’ll find what is termed the lock-shield – valve. When you come to inspect your radiator, don’t worry if their positions are reversed — they will still be equally effective.

The first thing to do when removing a radiator is to close these valves. The hand-valve is straightforward, but you’ll have to remove the cover to get at the lock-shield valve. You’ll be able to close this valve using a spanner or an adjustable wrench with which to grip its spindle.

As you turn it, it’s a good idea to note carefully how many turns it takes to close. And you’ll find this task slightly easier if you mark the turning nut with a piece of chalk before you begin. The reason for all this is to maintain the balance of the system. After it was first installed, your system would have been balanced.

The lock-shield valves of all the radiators were adjusted to give an equal level of water through-flow so that they were all heating up equally. So, by noting the number of turns taken to close the lock-shield, when you come to fit the new radiator you can simply open it up by the same amount — so avoiding the somewhat tedious task of rebalancing the whole system.

Once you’ve closed both valves. you can unscrew the nuts which connect the valves to the radiator inlet and outlet. Do these one at a time after having placed a low dish under each end to collect the water and protect the floor.

Use an adjustable wrench to undo the coupling nuts. It’s wise to hold the circulating pipe securely in place with another wrench. Otherwise, if you apply too much pressure to the coupling nut you risk fracturing the flowpipe, and this would cause you a lot of extra work and expense as well as causing quite a mess.

It’s a good idea to get the radiator out of your home as soon as possible-just in case it leaks any remaining dirty water on to your carpet.

Taking out old basin taps

When replacing old taps with new ones the most difficult part of the job is likely to be— with so many plumbing operations removing the old fittings. Let’s first consider wash basin taps.

You must, of course, cut off the hot and cold water supplies to the basin. The best way of doing this will usually be to tie up the float arm of the ball valve supplying the cold water storage cistern so as to prevent water flowing in. Then run the bathroom cold taps until water ceases to flow. Only then open up the hot taps. 1 his will conserve most of the expensively heated water in the hot water storage cylinder.

If you look under the basin you will find that the tails of the taps are connected to the water supply pipes with small. fent/ accessible nuts, and that a larger — often inaccessible pack-nut secures the tap to the basin. The nuts of the swivel tap connectors joining the pipes to the taps are usually easily undone with a wrench or spanner of the appropriate size. The back- nuts can be extremely difficult – even for professional plumbers!

There are special wrenches and basin or ‘crows foot’ spanners that may help, but they won’t perform miracles and ceramic basins can be very easily damaged by heavy handedness. The best course of action is to disconnect the swivel tap connectors and to disconnect the trap from the waste outlet.

These are secured be undone. Then lift the basin off its brackets of hanger and place it upside down on 1:4-* floor. Apply some penetrating oil to the tag tails and, after allowing a few minutes for it tir soak in, tackle the nuts with your wrench a crowsfoot spanner. You’ll find they arc much more accessible. Hold the tap when you do this to stop it swivelling and damaging the basin.
