Re: How to find and stop a slow leak in basement ceiling
Are you sure it is even a plumbing leak? Plumbing leaks are usually not silent, if they are under pressure. And they get worse in a hurry.
Or it could be in a waste line, is there any plumbing directly over the area?
Even at the basement ceiling it could be a roof leak. Is the spot under an open floor area or under a wall? If it is under or nearly under a wall, check up in your attic. You may have to spend some time up there. Use a good bright light, water stains should be apparent. If it is a roof leak, it may not even be right over the point it is getting into the lower area. It can run down a rafter and then run down a wall and make itself known at the basement ceiling.
Waste not, want not.
Use it up. Wear it out. Make it due, or due without.
