When the water line to your house ruptures, you'll probably need to get emergency repairs. A ruptured water line wastes a huge amount of water, and that can drive up your water bill fast. There are two ways to replace a water line. One is through digging and the other is a trenchless method. Here's how they compare.
Trenchless Water Line Replacement
If it's possible, your plumber will probably choose the trenchless method of replacing your water line because it's a lot less disruptive. To do this, the plumber will pull a PVC pipe through the old pipe. PVC is approved for use with drinking water, and it lasts a long time. A PVC pipe also has no seams or joints, so there's a low risk of another leak in the future.
The plumber has to dig a few holes for this process. One will be near the water meter and the other will be near your water main valve. The pipe is then inserted in one end and pulled through to the other so the new pipe can be connected to the valve and meter. Your old, damaged pipe is left in place and is no longer in use.
Water Line Replacement By Digging Up The Pipe
Sometimes a trenchless approach isn't possible. You might also prefer digging up the old line over trenchless repairs. For instance, you may not want plastic water lines used for your drinking water even though they are okay to use. If you prefer a copper pipe, a trench has to be dug up to pull out the old pipe and put in the new copper pipe.
Replacing a water line with this method can be disruptive and expensive, especially if the pipe goes under your driveway as it may have to be torn up too. You may also lose landscaping in your front yard, and replacing the plants adds to the cost. Digging the trench is an added expense too, and the deeper the line, the more the excavation costs.
Before the plumber recommends the best way to replace the water line, they may send a video camera through the old pipe to find out how deep underground it is and the exact location of the pipe. This is a way to gather information since the camera should have a transmitter that sends back its location as it moves under the ground.
Once this is known, you can discuss your options for water line replacement with the plumber, and take into account the type of disruptions necessary to get your plumbing operational again. Contact a plumber for more information about water line replacement.Share
