Unfortunately...... you have the flange nut back to front. The "disc" or "flared"  side should be flush to the tank wall!!!!!

[Dave Willis]

That's what I thought!   

[tlwcs]

I still can't understand how you get the nut tight on the back of the flange when you can't reach it being so close to the bottom 

[Smurf]

Here we go talking nuts &  flanges again. lol

For god sake someone please do a vid how to fit one of these things properly as I'm getting very confused.

[nathankaye]

Oh well, it works either way 
No more leaks and its tight together.

Until tomorrow I'm guessing. And thought I was crap a diy but it's nice to be reassured  I'm not the only one. lol

The nut inside has little pimples on the surface which are enough to bite into the tank surface. Tighten the outside nut with a proper immersion spanner from Wickes and bob's yer uncle.

I know, I fitted mine 2/3 of the way down my 500 upright, it was as far as I could reach.
This is fitted at the bottom of his tank, so how was the nut with the pimples located onto the flange thread? I also remember there was very little thread protruding.

If the flange nut was put on the proper way round Nathan would have two surfaces flush to both sides of the tank. A smear of plumbers mate on the outside flange would suffice. As it s he's hoping the nut inside the tank stops it leaking (it probably won't).

I know  but how do you locate the thread for the nut

Dead easy. Look at Wolfgang pic. The mechanical flange is made of two parts so it's like a hollow tube with a nut on the inside. You lower the nut on a wire inside the tank,. From outside the tank you grab the nut with a hook through the tube and draw it up against the tube. Turn the tube from outside until the threads bite the nut and away you go. Once the flange is done the element can be screwed into it.

See? Two parts one inside the other

Maybe, just maybe, I may finally understand.  Thank you

Doh! Well its a learning curve  when//if it leaks again, the plumbers bait stays flexible so can wioe that of. The exhaust paste i can crack off and simply ssitch it around. But for now i heated up what water remained in my tank (around 200ish litres) to 45degrees and it sprung no leak. I then topped up water with cold (about 15degrees from ibc) and no leak. Water in tank at full level was 22degrees and stuck immersion on over night for 8hrs. Tank temp was close to 50 and  no leak with hot half a tonne of water and no leaks today from tank. So hoping this will last some time.

But still on slight learning curve, as all hoses become very soft and need to tighten all connections on hose etc. But thats sorted now and happy days.

[nathankaye]

Where theres a will theres a way. Might not be the correct way, but a way all the same.
Or as some may say, im very willing.
 

Same with getting the immersion way down at the bottom. Drop the flange down tank on a wire and poke your fingers through your cut hole and pull thread through. Ptf it or put some sealant on it and then using an immersion spanner and after your wheatabix! Tighten the life out of it.

It's not a big job to turn it round mate. Probably take you 5-10 minutes. I would do it when you get time as it gives rigidity/stability to the element.

[Jonny 87]

It will be when your tank cools down that you may spring a leak mate.

With the warm water it will expand the plastic slightly and plug any gaps, then as it cools and shrinks then it could leak.

Like peavey says just switch it around this weekend and bobs your uncle.

[Smurf]

Nathan I did mention in a previous post when you first posted some pics  it looked like it was fitted on the pish. If seated and fitted correctly these things  should not leak. Also then when looking inside of the tank should not look out of  line from the walls of the tank.

[nathankaye]

I must just be stronger then, at tightening my nuts  as several days of water being over 50 degrees C,  sloshing about in the tank. Late eveing blasting cold water into tank to fill her up and again heater goes on. Currently with no more leaks or water damage.

I know it can be nust as easy to re do, but im that busy at the moment i cant be arsed to drain my tank down and fetch it all back out the van and sort out. Im sure if it does fail me i will be cursing n sishing i did spend  some spare time on it. But if its not broken, why fix it.

Lol, im so defensive
