Good, thats that sorted. Out of interest, 3 - 4 years is about average
for
hard water.
I have a water softener, in twenty five years I have replaced the element
once, and that was the one which was here before the softener. The water
heater is on semi-permanently too!

Yes, just replaced the immersion in a property yesterday- 4 yrs since the
last one replaced. Had to call plumber in the end because I couldnt shift
it, and was at stage of nearly twisting the boss off the top of the
cylinder.

Much blow lamp and it eventually came free, but we did crack the solder join
where boss meets cylinder and were lucky it soldered up and sealed with new
element in place. Cylinder will have to be changed next time element goes.
