Soldered or compression please

[guest5234]

I am removing a radiator permanent from my kitchen, it has the drain valve as it is the lowest and end of system rad.....what is best to cap of the pipes please...a compression drain valve and stop end or soldered.
Thanks.

soldered if there is no water about

it wouldn't be a bad idea to renew the drain tap while your at it

Thanks, what do you mean the drain tap Kev?

and if I go with compression are the JG Speedfit Drain Cocks OK, it says they just push on to the copper pipe with no tools needed....how does that work?

it seals with an o ring and holds the pipe with a steel grab ring

if you use pushfit either clean the burr from the pipe end/s
or use a pipe cutter

if you look back ive stuck an edit on my last post for you

if you mean it has the drain cock because it is the lowest point in the system, it's a good idea to keep it. If there will (normally) be no flow in this pipe, because you have removed the rad, you might consider putting a full-bore cock on the end, with a 3/4" hose connector. This makes it very quick and easy to drain the system when necessary, and the fast flow will help wash out loose serdiment.

I fiited a washing-machine tee on mine. Some people say the heat will age the seal, but this would not apply in your case. Fit a 3/4" blanking nut on it so that it will not leak if someone accidentally turns it on.

btw it is very difficult to solder pipe that is not perfectly dry.

An point worth noting.

If you use pushfit fittings the draincock Kev has shown will not fit, as the tail will e too short.

You need a compression fitting.

You could always get a speedfit or Hep drain cock with a longer shaft

You certainly could.

On the other hand a compression fitting is better.

And congratulations on the 15000 posts
