Anyone got a good technique for draining rad with frozen tails

[WaterTight]

And not getting water on freezing clamps/heads?

Sometimes if tails are short and/or tight against wall it's difficult to get a rag in between or tray under union.

Crack open nut joining valves to radiator tails. Switch on wetvac and suck up water as it comes out.

Obviously only works if you have a wetvac. Brill bits of kit.

if theres movement then crack off the rad nut on one side then quick fix on a hose set up that you have made up that will screw on to the rad nut then just open up the bleed key and let the air in sorted!!
what you tring to do remove the rad from the brackets?

I always shut off the valves first, drain the rad and then freeze. If one isn't closing just shut the other end and drain from that end.

I concur with the wet vac idea though.

Need me a wetvac!

Thanks chaps.

I always shut off the valves first, drain the rad and then freeze. If one isn't closing just shut the other end and drain from that end.

Then what do you do, whip the rad of and cap off the non-shutting valve before freezing?

What would you do if the rad valve leaks from the top and it isn't one with a gland that can be repacked? You then have movement of water and it may not freeze. I've had that once and a blob of LSX did the job and once where it didn't.

The way ahead as far as wet vacs are concerned. Bomb proof.

Also yet to find a blocked sink/shower/basin waste he can't unblock. Loves the jobs you hate.
