  • Locating Lead Water Service

    What would be the best tool(s) to locate buried lead water services. Is it even possible?

    Re: Locating Lead Water Service

    If we have to locate a water line that is untraceable, we use our fisher xlt30 listening/leak detector. We open the water in the house and can locate the line by listening for the flow. We use the ground probe and have been within 6 or so inches every time. There maybe an easier way but this is what we found to work the best for now.

      The SR-20 and SR-60 excel in line locating applications. Locating lead (Pb) in dry sandy soil should not be a problem. It can get difficult in wet soil conditions. Lead is not a great conductor and current will want to bleed of into the soil or other more conductive materials near by.

      In these situations, you can push a camera or fishtape down the line and then locate the camera line. This is an effective way of locating lines made of any material as long as you can get access to the inside of the line.

      I thought that most lead water lines had been replace long ago?

        No, we still have thousands of lead water services. Maybe tens of thousands. The agressive lead abatement program we had several years ago was a bit of a failure. Caused more lead to leach into the drinking water than if the pipe had been left alone. More taxpayers dollars being wasted by the government that thought they knew better. The lead pipes that are left are being replaced on a 'need only' basis.

        I wasn't sure how well lead would transmit but the fishtape with Seektech idea sound good.

        What about using the Scout with the Navitrack Brick?..

          Sorry but can you explain the last statement a bit better please.
          If you push the fish tape down the line how do you locate it!
          Do you need to use a navi brick to induce a signal into the fish tape.

            There are a couple of different ways to locate a line with a camera or fish line. The easiest way to do it is with one of the new camera monitors that has the integrated line trace feature. With this feature, you can connect any transmitter (such as a NaviTrack Brick or ST-305) to the monitor and apply the signal onto the entire length of the camera line. One transmitter lead is clipped onto the monitor and the other is clipped to the ground stake. You can then use the line trace mode on your locator (Scout, NaviTrack, SR-20, etc) to find the line.

            An alternative is to use the sonde mode and locate the sonde in the camera head as you push the camera through the line. This maybe the best option in extremely dry conditions.

            If you are using a fishtape, after you push it into the line connect one transmitter clip to the end of the tape and the other transmitter clip to the ground stake. If in a plastic or lead line a higher frequency (33kHz or 262kHz) will probably work best.

              it's amazing how many of them we still run into. Sediment from the water has built up on the inside of the lead service creating a barrier between the lead and the water. It isn't ideal but most people won't spend the money until they Have to. I do refuse to repair them, once they've been disturbed i'm not going anywhere near them unless it's to replace the Whole line.
              No, it's not rocket science, it's plumbing and unlike rocket science it requires a license.

                Like Mojo said ,people won't spend the money unless they have to and once there is a problem,you could end up with a huge liability problem should *anything* happen.
