Repiping refers to the total replacement of plumbing systems in a home or other building. There are many reasons for repiping. An aging system is ripe for problems. Old pipes may contaminate the water supply or begin to leak. Ineffective materials are another reason for repiping. For instance, polybutylene pipes have been proven as ineffective and can fail without warning. They are no longer in use, but many homes and buildings still have them. Many question the safety of PVC pipes as well. Some brass fittings fail when they are dezincified. They also pose a danger to water supplies and property. An inspection and repiping can prevent these problems from occurring.
The first step in the repiping of a home or commercial building is an in depth inspection. This will reveal the extent of the job to be done. A simple pipe repair may be all that is needed. On the other hand, out dated materials like lead pipes and cast iron pipes must be removed and may involve more invasive pipe replacement. A complete repipe of all the plumbing in a home repair will include all domestic and potable water piping and waste piping. New hot and cold distribution or main pipes and branch pipes is also included. A quote is issued after the inspection. It includes the prices for all materials of replacement and labor. It does not include new fixtures unless you specifically request new ones be installed as part of the repipe.
Preparing for the repipe is the next step in the process. A down payment is often required before work begins. The system is planned out and materials are purchased. The client receives notification of how to protect their furnishings and belongings during the construction. The ceiling, floors, and walls are cut open to expose the old pipes. The water is turned off and the pipes are removed. Expect to be without water for 1-3 days.
Pipe is replaced by sections. As each section is finished it may need to be inspected by a county building inspector, this may make the process take a bit longer. When the repipe is completed, it is tested to ensure that it is functioning properly and is safe. Then the walls are repaired and finished. A separate drywall contractor may be brought in for this stage. When everything is completed, the plumber will give you a tour of your new plumbing. The rest of the money is due at this point and another home is ready for safe and effective water distribution.
