How to removing valve with hemp paste on??

[beesley121]

Hi guy,

I'm trying to replace a 2 port valve with hemp and paste on it. I tried everything to get it to move but it won't budge

Any ideas other than cutting the pipe as it's 28mm and I don't want to have to buy a length and fittings for a little job

Help please!!

I have a big adjustable and big set of grips that come in very handy at such times.
could you cut into the nut to loosen it?

Lots of Heat & a hammer ! Get it nice & hot then a few hits on the brass nut usely shifts it !!

 

[Mike Jackson]

I'll second the heat.

Try WD40. If no good, heat. I do not really know what is in WD40 to do it but I think I recall it softens the hemp even if the paste and have gone hard.

Heat, Hammer and swearing usually does the trick

nut splitter?

Heat, leverage and brute force. Get it hot enough and it always shifts as long as your not melting anything in the viscinity.

Another vote for heat. Get the blow lamp on it.

Lots of heat and when you get your Gordon's on try not to squeeze the nut, grip tight but not squeeze if you know what I mean lol

I had THE most stubborn immersion heater today.

Tried heat, then crack it release spray, then pipe freezing spray, then heat again, and shocking it with a lump hammer...... in the end I had to cut two slots into the body of the element so when I put the immersion spanner on it, and levered (with 24" stilli's I should add) it eventually cracked and went.

Moral or the story, persistance over comes resistance!! LOL

Heat and brute force every time.

I made myself an immersion spanner out of an old box spanner, I welded the box spanner into a pipe about a foot long with a 2 foot handle on it .
hard to explain but it's never struggled on any thing since!

My immersion spanner is a box spanner, that I fix a bog set of two foot stilsons to. I was gonna bend the cylinder before I got it out with brute force alone. I'm not a small bloke and I was pushing on it with every ounce of strength I had!! Never had one like it before.

I like your idea, and would like one myself!!

There was a battered B&Q immersion spanner in the airing cupboard!! Someone else had tried it before me, and bent their cheapy spanner!

The problem with excessive force is that you can tear the copper cylinder. Also if you use heat on a cylinder insulated with foam you are asking for trouble.

True, I sprayed libberal "cool gel" around the insulation. I used the blow torch in the immersion spanner (socket type). It didn't damage the insulation one bit.

I wasn't giving it loads and loads of heat. I did give it loads of welly though. I had warned client that the cylinder might distort. I always do, before I start any immersion swap.

Luckilly it was a good thick walled cylinder. Not like some of the thermals stores I've dealt with. The Gledhill Pulsacoils. It's waffer thin on those. Never damaged one, but I'm sure loads of em must be in the great scrap heap in the sky.

I put a tutorial for a failsafe way of removing a stuck in immersion element on the hints and tips section. A dremel would be an alternative to using a hacksaw blade as I suggested then.

 

[Dannypipe]

Yeah, I read it. I pretty much did as you say, but I used a multisaw with a metal blade. Instead of cutting all the sections out, I simply took a piece out (like a slice of pizza) then when you crank it, the immersion will slightly distort and break the seal.

Worked for me.
