Re: Locate water line leak
A few things to keep in mind when attempting to locate underground leaks between two locations:
- If you have an above-ground pump, the foot valve (a special check valve with a screen on one end) at the bottom of the well is a common point of failure. If you have a submersible pump, there will be a check valve either at the outlet of the pump or near the pressure tank on the line coming from the pump. That can fail, too.
- Black plastic pipe is typically sold in 100 and 300 foot lengths. If there is a leak at a fitting, there's a good chance it will be at some multiple of 100 feet from one end or the other.
- Tree roots can crush black plastic pipe. The pipe can also be damaged where it passes under a driveway.
And for repairing black plastic pipe, you can heat the pipe with a heat gun to make it easier to insert the barbed fitting. Then heat the pipe again when clamping it down, but never so hot that the pipe becomes soft enough to permanently deform. Use two hose clamps at each barb for the most secure joint.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
