Yes, repiping a house can be difficult. The process involves:
- Shutting off the water supply to the entire home
- Removing all fixtures and faucets connected to existing pipes
- Installing new piping throughout the house
- Testing for any leaks or damages in plumbing systems.
The difficulty of this task depends on factors such as type of pipe used, access to walls and ceilings, location of main water line and so on. Professional help may be needed if you are not familiar with plumbing work.
