    Quick question, I'm getting a bit of a slow leak out of the bottom the geeza heater I have beside my tank, it's causing the switch to trip when trying to heat the water. I need to swap it out, I have a new heater to go in, I just need to know, and maybe I'm trying to simplify this but is it a case that I turn of all the water in the hot press, anything with a turn handle, screw off the nut at the top and the one at the bottom, expect some water to leak? Remove the old geeza, using new nuts and copper compression rings install the new geeza, rewire to switch ( not forgetting that power off at mains trip before going near heater, which is the 1st step!) open up valves and away I go ?

    here is a Geeza similar to the one i have to replace:

    You need to drain the cylinder before removing the heating element or you will end up with 100l or more landing in your lap when you open the fittings at either end of the heater. Find the cold water feed and close this valve, then attach a hose to the drain valve at the bottom of the cylinder, the hose should lead to an outside shore without rising above the height of the drain valve, open the drain valve and let the cylinder empty. No need to close any other valves. Also make sure that the new heater fits exactly, no big deal if it doesn't as long as you can shorten / lengthen the pipework to suit. Make sure the hose is a good fit on the barbed fitting of the drain valve, or it will leak. I usually secure it with a jubilee clip.

    spot on Pete, thats what i figured out, took me a while but got my head around it. The anoying parts was that when i fitted the new Geeza and had everything back in place and did a test run and turned it on, it sprung a tiny little leak, so i had to strip it all out and refit the old one, return it the shop and start all over again with the replacement ......so i can now do it with my eyes closed !!!
    The drain valve was only about 3 inches from the ground so it took quiet a while to get all the water out of the tank, got it eventually!!

    thanks again
