Title: Radiator Plumbing
Post by: LynnLegend on 01.03. 2018 10:14
Hi all,

While trying to fit a radiator I have managed to round off the flipping brass bit which sits beneath the valve cover. I have tried grinding it to give it a new edge but my tools just seem to shred it. I wasn't even aware that I'd overtightened it.

Any advice would be great fully received. I really don't want to fit a new valve.  *pull hair out*

Thanks,

Sam.

If you have just been fitting the rad then I guess you can be sure it is in the closed position. Only asking because if you leave them wide open against the stop then they jam up hard that way. On opening once I hit the stop I then close a half turn.

I had one do that and managed to free it using a whole lot of heat on it and the applying a Mole Wrench on the rounded square very tightly. (What is the generic word for a Mole Wrench?)

Well done Dutch you've put a smile on my otherwise grumpy pi55ed off face!

Butch - yes it's definitely closed, I would go as far to say it's extremely closed. Next time I will make sure it's not quite so tightly closed, although as I said, I didn't think I'd overdone it.

My tool set doesn't yet have a blow torch, so that might be a necessary addition.

Ditto here.

You might try loosening the gland nut a tad.

If draining the sytem to change the valve is not practical I've used a pipe freezing kit, (https://www.youtube.com/watch?v=HrPwz6NQbGc (https://www.youtube.com/watch?v=HrPwz6NQbGc)) with success a couple of times. Obviously need to work with a cold system so may not be practical in this weather.
What about a small Stilson, (pipe wrench); it will mark the shaft but that may not matter much.

Often wrongly called  Vice grips, in fact made by Vise so Vise grips

Most useful instruction is "Attention! Tool may get hot!"  *eek* Keep forgetting that...

@ LynnLegend; maybe filing two parallel flats with a small file to fit a small spanner?

My old trade, 7" or 9 " pipe grips will grip anything I have had them since 1970, made by footprint. New valves are only £5 a pair last time I looked. Just ask if you need anything else. You may need a tail allen key to get the old tail out.

Like many things toolwise - often copied seldom bettered

Thanks all for your suggestions and comments.

Think I will have a go with a pipe wrench first, failing that, ice pack and change the valves. I will buy a footprint wrench, based on your recommendation.

Wish me luck!

Sam.

You mean Petter?
There's no rad valve on earth that will withstand a pair of Stillsons especially as all you'll need to do is to crack it to get it moving. Adjust roughly where you want it and then sit back and wait for summer when you can replace it at your leisure.

 I needed to use it for a short time then put it down but then had to move it, so guess how I picked it up.. *bash*..the burner tip is now painted with red flame-proof exhaust paint....

Footprint pipe wrench did the job - very well made tool, a worthy addition to my tool kit. I have one terrible mangled valve now, but can replace in the summer. Room toasty hot.

Thanks all for your help!

Sam.

That is a modern rad and valve. If you drain down a change it, buy a new washer for the drain down cock which you can fit before you refill the system. I have never been beaten by one of those valves, try not to heat it up you will damage the spindle packing. Regards.
