Just burst my immersion heater tank.

A professional would’ve wrapped some PTFE tape round it, then told her they’d come back in November to finish it

PS Taking old immersions out never seems to work. They cement themselves in.

 

You did leave it full of water, so it gives the spanner something to push against, then drain it once it has eased open ?

If you do it after its been drained, it bends the tank.................

 

So do I, the only reason I know of this method is because I warped several tanks whilst working for the Electricity Board - they had a promotion on immersion heaters to push the use of off-peak economy 7 electric and had the smart idea of getting electricians to do the installation.

It was carnage, we kept a plumber in work for months, making good our damage.

 

Wd40. Soak the absolute granny out of it, and when you think it can’t take anymore, spray some more on. Walk away, don’t be tempted to touch it. Wait wait wait. Then use an immersion heater box spanner. Gently tighten then loosen then tighten then loosen etc etc until you get movement. Then drain the cylinder. Once the element is out. Clean the face of the cylinder with fine sandpaper or at least wire wool. Push on fibre washer. Apply a thin smear of jet blue paste or lsx to threads. Tighten gently. Don’t over do it. Go to pub.

Although I’ve not tried it some plumbers suggest you get the cylinder really hot before you put the wd40 on, so as it cools and contacts then the wd is drawn into the treads.

 

Booo booo

 

.... or plusgas?

 

There’s plenty of plumbers I know that wouldn’t think that’s such a good idea
