Question:

I have a pinhole leak in my copper pipe under the bathroom floor?

Despite turning off the water at the mains it still continues to leak which makes me wonder whether it is a pipe for the central heating system which was installed after the house was built. There are numerous pipes connected all under the floor, some to the hot water immersion tank. The water is black which might confirm this. I have temporarily plugged it with one of your subscribers suggestions i.e a toothpick but will find it difficult to plug it wither rubber clamps etc if it is still wet.Any suggestions other than calling in a plumber.

Answer:

a pneumatic themostat?. that means its air controlled. huh?. well water will not cause a fire. never heard of one, im outdated already!! shucksgood luck with it!

Unless there was some sort of physical damage causing the pinhole leak or the pipe was defective, if you have one pin hole, you either have others or will have more soon. The pipe itself really needs to be changed out for a proper repair. AND, finding out what caused the problem is essential, or you will be finding more pin hole leaks in other sections of the pipe run soon. If this is for a hydronic heating system, there are chemicals that can be added to neutralize the acidity that is eating the pipes away. If it's for a water supply, then a filter needs to be added to the water main to help control the pH of your water. IMO, call in a pro that knows what they are doing. Good Luck!
If you can put a toothpick in the hole you should be able to put a small sheet metal screw in the holePermatex the screw good before screwing it in
