I want to put an outside tap round the side of the house so I can wash down when the dogs have been out there. I have a downstair loo with a sink on an outside wall and I can tap into the pipes and run them through the wall, then put a tap and hose on. Thing is, I would prefer the water to be hot as I could also use the tap to clean other things like the car and also its better for washing down after the dogs. As I have an instant hot water boiler is it OK to attach the tap to the hot pipe and will it work like my indoor taps as in when I turn it on so far the hot comes out.
thanks
