"stops a Dishwasher tap that is not used from dripping if it is accidentally turned on in a cupboard. I think all new homes should be fitted with them and they can be taken of if a machine is fitted and needs both hot and cold feed."
"EXCELLENT - needed to blank off a washing machine supply tap as new machine needs only one supply. Had limited space to seal pipe properly - this is a quick, easily and reliable fix! Comes with an inbuilt large seal - just screw it on and job done!!"
"But its the correct size to blank a radiator valve off - so saved time because after removing the radiator the valve leaked - put on this blank until I sourced new valves super job sealed immediatly."
"I bought this based on the excellent reviews to block of the hot fill when I took out my old washer. Unfortunately the ball valve had a slight drip and when I fitted this cap the drip continued. Upon investigation I could see the threads ended before the bottom of the cap (not uncommon on machined parts) but the washer was too thin to seal the cap between where the threads end and the mating faces. As a result I had to put in a 3/4" tap washer that was thicker that I had in my plumbing box and now it seals."
