static tank in your van
has any one on here managed to do this.
The reason i am asking is that to secure the immersion heater to the inside of a the tank you need a 2.5 inch flanged locking nut and i am having a bit of trouble locating one,tried a few plumbing merchants but no one as one in stock

cheers bob

I just cut a hole tight enough (actually I made a mistake and cut it a bit bigger by accident; but it was still okay) to put the immersion element in the tank and screwed the small flange thing on the other side.

Then used loads of good quality sealant.

It looks like a bag of nails, but it works a treat.

did the flange come with the immersion?,i have a immersion element but no flange and from what i remember they dont normally come with one because they screw in to a thread when being inserted into a copper tank,but i could be wrong if i am i will buy a new one

Bobplum - a flange is a big octagonal (?) nut thing wot goes on the back of the thread. They are quite heavy duty often out of stock at toolstation and IMO not needed.

You can also get a smooth round lighter one which also does the job fine.

You can also cut the hole a fraction small and wind the immersion in cutting its own thread with no locking ring at all.

The middle option is fine as long as you can grip the inner ring until it starts biting into the plastic. (me holding it with rubber faced builders gloves while my son in law tightened the immersion worked fine for me)

But!!!!!! Do not use an adjustable hole saw - get the right size or you may find the arms bend and the hole is not cut truly round and you get leaks which you can't seal and you spend two days faffing round with heat guns and glue and sealants and end up having to buy another tank anyway!

Do not ask me how I know this!    

On a lighter note I have cut three holes in three new tanks and fitted three immersions successfully and all are still fine leak-wise.

i will probably give a it go next week end,i am going to try and source the flanged lock nut and a washer and then cut a slightly smaller hole,wind the immersion thru and lock it and seal it

A Mechanical Flange is what you're after and they sell them at Toolstation in Chester as that's where I got mine from
