Background I've moved into a flat recently and have been renovating. I'm doing all the work myself - have installed a new bathroom, new kitchen, new shower and cistern etc. and now I've realised the cold water tank is perished and beginning to leak.
The plumbing cupboard is a complete mess, it seems as if there have been about 4 different generations of plumber with each taking the easiest and quickest route to do what they want, and ignoring any future hassle this might cause.
For reference, we don't have a boiler in the flat, other than the immersion boiler shown in the picture below. The cold and hot water directly coming into the flat are what we use.
Is it OK to remove the cold water tank entirely? I see the hot water vent is going into the tank, but as we never use the immersion boiler and don't have any other type of boiler, is it safe to simply route that into the drain?
I would be keen to remove this ticking liability.
