Hi,
I am trying to drain my tank so that I can change my immersion heater element (the lower one in the picture).
I have viewed almost every video/resource i can find on this and every single one mentions a drain off valve that you can attach a hose to that allows you to drain the water from the tank (see image "tank2bottom.jpg for image of the tank). In the bottom left of that image you will see a pipe that has a tag on it labelled (drain off valve) - You can see a closer picture of this in image "drainvalve2.jpg"
The drain off valve looks to have a "tap" that should turn on the top but on closer inspection (and through many different methods) this does not seem to turn and actually seems to be part of the whole metal junction from what i can tell. (unless over time it has fused to become one piece of metal?) - i have tried WD40 to loosen it but with no luck. - Coming out of the bottom of this junction is just the end of a bolt (screw) - i assume the bolt goes all the way through the junction?.
Every video/image i can find of one of these drain off valves or of someone emptying there water tank, the drain off valve always seems to have a nozzle from which you would attach a hose but this junction labelled "drain off valve" does not seem to have this. (Is this a different type of drain off valve or has it been incorrectly labelled?) - I have looked all over this cupboard/tank and there is nowhere else that could be even remotely considered a drain off valve (and as i said, this part has a label hanging from it saying "drain off valve")
Any help on how this type of "drain off valve" works would be appreciated. or if you can let me know if its even possible to drain the tank using this "drain off valve" that i have. (please note, as far as im aware the whole system was installed in 1990 and none of it has been changed).
The only other option i have is to remove the cap/plug where the top immersion heater element would go (if i had one) and siphon the water out? however, i assume the water in the tank is above this level so as soon as i open it water will come pouring out so thats a no go i assume?
Any help/advice would be appreciated and please ask for any information/pictures you need to assist.
(Just to note: i have spoken/explained this over the phone to a plumber and he has said that if there is not a drain off valve then it would require much more work to syphon it and would cost alot and unfortunately i cannot afford anything right now (id have much rathered get someone in to do it but its just not possible at the moment money wise) which is why im trying this myself - im very confident that if i can drain the tank then i could do the rest of the work on my own). Its been 2 months without hot water now so id really love a hot shower before winter sets in fully
Many thanks in advance.
