Drain cocks

[jamesarm]

Hi, I was wondering if anyone could advise me on the below please;-

I have a victorian property with a separate washroom/outhouse and need to turn off the water to the outhouse before alterations to make it habitable.

Currently there are two lead pipes reduced to 15mm copper, in the outhouse both supplying mains water. both these pipes go down into a screed/concrete floor and I loose track of them.

On the ouside of the main house there is one drain cock for the central heating, and then another two close together near to where mains water enters the house.

Any ideas why I would have two draincocks? Would one possibly be a bypass or similar for mains water for the outhouse (probably wishful thinking)?

Thanks,

James.

more than likely there there to drain off the cold water.e.g if you go overseas in winter.its basically good practice to do this.but see it less these days.hell iv never even touched one when i do see them, as i know the pitfalls off a bad drain off,to much hassel.also water regs usually recommend a drain off after an incoming mains stoptap.
