Water hookup from the city to your home’s main water supply and back out to city sewage costs anywhere from $500 to $20,000. Your total price depends on where you live, the distance of the water main line from the residential extension, and whether your state or local county will subsidize this expense if you're building a new home.
To switch from well to city water, you’ll need to run a private main service line from the nearest main city line to your home’s water supply. The process involves a plumber shutting the pressure off the well water and activating the private line running to your home from the city water supply. It costs around $3,000 on average to make this switch.
It can cost up to $600 on average to replace a main water shut-off valve in a typical residential property. While you can try tackling this job yourself to save money, hiring a pro ensures proper handling and building code compliance. Mistakes aren’t easy to cover up, so hiring an experienced technician is best.
Most home insurance policies do not cover water main replacement, and homeowners must pay for it outside their insurance coverage. Damage sustained to a residential water main line is usually considered external as it relates to your home and what's insured inside it. That said, consider contacting your insurer about available coverage.
