Repiping is the replacement of pipes in a home or building. A whole home repipe is the complete replacement of a property’s water supply lines, including both the hot and cold water pipes from the water source to the fixtures. Often, this involves removing the old pipes before installing new lines. Repiping does not usually include drain and sewer lines. 

The repiping process involves 4 main stages: 

• The prep work – Because repiping involves cutting some drywall, the process can create some dust. This means furniture items and other items in the area will need to be covered to prevent them from collecting dust. During the home evaluation, the plumber will inform the homeowner of areas they will need access to so that any items can be cleared before the work begins. The plumbing company should also obtain any necessary permits and include them in the cost of the repipe. 
• The repipe – The water will be shut off before the work begins each day and turned back on during the evening. The crew will work on removing the aged, deteriorated system and replacing it with new pipes. Homeowners will be informed ahead of time how long the process will take, which is usually one to three days, depending on the size and complexity of the home. 
• The inspection – Following the completion of the repiping process, the specialists will run tests to ensure that everything is operating correctly. During the inspection, the technicians will look for integrity issues and confirm that all connections are installed properly and fully functional. Finally, the system will be pressure tested and then flushed out. 
• The cleanup – All remaining mess and materials will be taken away from the work area. The holes in the drywall will be patched up and painted over to look as good as new.
