is it easy for me to replace? diy or do i need a professional.
also the electric shower unit in the bathroom i would like to replace it. could i buy a new one and just refit using existing connections/wiring. again diy or professional
finally the radiator in the bathroom is not working ive been told one of the valves on the right handside can easily be turned and it shouldnt do that and needs replacing. i've been told the valve costs a fiver or something, would this be something i could fit in?
not an experienced diyer, electrician or plumber
