Capped pipes in old tank cupboard

[Grahamd]

A work mate has 2 copper pipes coming up through the floor in what was the old tank cupboard. Both pipes are capped off with push-fit ends but wants to cap them off at floor level. He's not sure if the pipes are still contain a water pressure. Apart from taking the end caps off, is there a way of detecting if these pipes still contain water.

Many Thanks

why not just turn the water off first

then open the downstairs taps

Thanks for reply Kev, will pass on your suggestion.

If there's now a combi boiler, chances are that capped pipes are hot water flow and (maybe) cold feed to the old cylinder. At least the hot will probably still be 'live'.
