i have a shower pipe in an alcove which has a continous small leak -however it is phsically impossible to get any tools or even bandage to tighten the nut. someone suggested turning off water supply , blowing water taps to force out any residue and then gloss paint leak area Is this a good idea or any other things that could be "painted pasted" over leak?
Painting a leak is a ludicrous idea. I'm afraid you'll have to find a way to get a spanner or a wrench to tighten it. BTW how did the plumber tighten it when the shower was fitted?
painting it to stop a leak wont last for 10 seconds!! you may need to do some more work and knock the walls about a bit to tighten the nut if that what it needs.
Halfords sell a paste for mending fuel pipes. You can shut off the water to the suspect pipe so that it is empty, and you get some of this paste, make sure the pipe around the leak IS DRY. Then press as much as you can around the area. It may take a few hours to set. I mended a leak in the petrol pipe on my car, it held for four years, I scrapped the car because the cam belt broke. This should be ok for water, as petrol is harder to seal. good luck.
1 rovert, that paste will not work, a fuel line is not under the pressure of mains water. The only way to fix it is to do it properly!! call in a plumber if you cant do it yourself!!!
