Older plumbing systems that spring constant leaks or contain toxins, like lead, will necessitate a full repiping of all the plumbing in your home. Although it will save you money and possibly protect your health, in the long run, to have this service completed, it can also be stressful. Knowing what to expect can help alleviate many of your concerns.
There are several options when it comes to choosing the materials for the new piping in your home. Copper is the industry standard for the main water lines and sometimes even the waste lines in the home. Plastic, vinyl, PVC, and PEX are the usual options for the periphery lines that connect to these main lines. These non-metal lines are durable and won't corrode, plus they are easy to repair in the event there is a problem in the future.
How long the project takes will vary. The size and age of your home, along with whether you are having all or only some of the lines replaced, can affect project length. For the average-sized family home, you can usually expect repiping to be completed in less than a week. Your plumbing service should be able to give you a fairly accurate time estimate when they are assessing your home for the project.
Your water service will be turned off during the repiping process, and your sewer lines may also be inaccessible. The good news is that these are typically intermittent shutdowns. Although there may be a couple of hours each day where all water is shut off to the home, often your plumbing service will be able to only shut off water to the area they are working in. If you have the ability to schedule work when no one is home, such as when you are away at work, you can avoid this inconvenience entirely.
The pipes will need to be accessed both inside and outside of the home. Outdoors, excavation will likely be necessary to replace any failing water mains, although sewer lines can be replaced via a trenchless method. You will likely need to fix the landscape afterward. Indoors, your plumbing service will take steps to protect your furniture and flooring. They will make cuts into the drywall to access pipes. Depending on the location of the pipes, flooring, shower surrounds, or ceilings may also need to be accessed. This damage will be repaired once the repiping is complete.
