I had a small sink in the corner of a room I’m using and it was in the way so I removed it. I cut the hot and cold pipes and went and bought something to cap them with. At the DIY shop I bought two of these little plastic end caps shown in the picture that seal using the pressure in the pipe.
When I turned the water back on the hot pipe sealed up perfectly but the cold did not. The end did not pop up and water started to dribble out the side of the cap. It was as if there was not enough pressure in the cold to make the little cap work properly.
so I wrapped it up with a load of the rubber sealing tape and it did the job for a few months but today there’s a drip, more than a drip, a little spray. I got down there and wrapped more round it till it looked like a rubber ball on the end of the pipe and it’s stopped for now but I’ll need to deal with it in the near future so I’m wondering what’s the correct way to seal a pipe like this?
Why did the little cap not work and if it’s because there is not enough pressure in the pip then what is the best way to seal a pipe end in this situation? Maybe I installed it wrong?
Any advise appreciated.
