Radiator leaking?
« on: November 18, 2018, 10:18:17 am »
The radiator in the kitchen is around 20 years old.  It seems to have sprung a leak somewhere in the middle and on the bottom.

Is this basically a new radiator?  Would anyone have an idea of the approximate cost?  Can I get this patched up or am I best replacing?

I am surprised it’s leaking after such a short life!

If you're sure that the leak isn't from the pipe connections and the water running to the lowest point then yes you have a split/corroded seam or porous steel.

If there's a lack of corrosion inhibitor in the system then 20 years is no surprise.

Well that's the more blunt way of putting it but as usual he's dead right.

Ok thanks.  It’s in the middle somewhere and definitely not at the valves!

Thanks t

You could try a CH leak sealant as a temp fix as plumbers/heating engineers will be busy next week (unless you are lucky), but not a high level of confidence. Sounds like a new rad.

I think I am surprised as I have never heard of a rad leaking.  I have just managed to get the radiator disconnected and there is a fair bit of sludge in it.  At least it was in the kitchen and not on the upstairs bedroom!

If I buy exactly the same size but a similar design are the fittings likely to be in the same place?

Obviously you can see if you can go straight replacement if the rad is a metric size, Screwfix stock Barlo rads. Adjustable exentions are available for the valves if the size is a little different. Dont forget to replace the olives and gently does it. You will need some PTFE tape for the fittings. The wall brackets may differ.

Thanks. I can find the same size 750 x 1600 but it’s not exactly the same design hence the question

Replace the rad.

Easy to do.  Excuseto run a cleaner through then an inhibitor.

Never having done a change before - it’s going to be interesting I guess!

So radiator arrived and I naively assumed it would all go smoothly but no, it turns out I need something called radiator tails.

The tails seem as expensive as the valves, so I think I will buy the valves (fit the tails for now) and then the valves, if and when I drain the system.  I realise I maybe making a mountain out of a molehill, but every day seems to be a school day at the moment!!
