My tap is leaking bigtime. It's one of those taps that has the one 'handle' which you turn left and right for hot/cold. I opened the cupboard before and the shelves were covered in water. The pipes going up through the cupboard to the actual tap are both leaking - but I can't see where from, only that they're leaking from where they go into the actual tap..if that makes sense. I rang the real estate agent and she said they can't get a plumber here till tomorrow morning. I've put a bucket and towels under to catch most of the water but these are filling up fast and I don't fancy getting up every half hr to change it. It's leaking a fair bit of water...runnage not drippage from BOTH the hot and cold pipes. I got under the house hno: to see if I could find somewhere to shut the tap off from the system but no can do as it's attached to the rest of the plumbing going to the upstairs etc. Is there anything I can do to 'disengage' this tap?
