Questions this calculator answers
What is a whole-home repipe?
A whole-home repipe replaces all or most of the water supply lines in your home with new material. It is typically needed when pipes are aging, failing, or made of corrosive materials like galvanized steel or lead.
What is the difference between PEX and copper?
PEX is a flexible plastic that is cheaper and easier to install. Copper is a traditional metal that is more durable, with a lifespan around 50 years. Installed, copper runs about $2 to $8 per foot versus $0.40 to $2 for PEX, so on a home around 2,000 square feet copper can cost roughly $6,000 to $12,000 more.
How many plumbing fixtures does my home have?
Count each sink, toilet, shower, bathtub, dishwasher, washing machine, and water heater connection. Include outdoor spigots and utility sinks if they are on the main supply line.
How long does a whole-home repipe take?
A whole-home repipe usually takes several days, depending on home size, complexity, and crew availability; ask your plumber for a timeline for your home.
Do multi-story homes cost more to repipe?
Yes. Multi-story homes need longer vertical pipe runs between floors, which raises labor and material costs. There is no fixed markup, so ask your plumber to price your specific layout.
