When repiping makes sense
- Galvanized steel pipes (common in homes built before the 1960s) that have rusted inside and choke water pressure
- Repeated pinhole leaks in copper lines
- Gray polybutylene pipe, prone to sudden failure
- Rusty or discolored water from the cold tap as well as the hot
- A renovation that opens up walls anyway
PEX or copper?
Both are good choices. PEX is flexible, quicker to install with fewer wall openings, and usually costs less; copper is durable and familiar. MJ will explain which fits your house and budget.
Partial repiping
Not every home needs everything replaced. Often the worst sections (the main supply line, or the runs to a kitchen or bathroom) can be replaced first, spreading the cost over time.
Common questions
How do I know what pipes I have?
Look where the water line enters the house. Gray metal that a magnet sticks to is galvanized steel; orange-brown metal is copper; flexible red, blue or white plastic is PEX; flexible gray plastic is often polybutylene.
How long does repiping take?
It depends on the size and layout of the home; many houses take a few days. MJ plans the work so you have water at the end of each day where possible.
Will you need to open walls?
Some openings are usually needed, and PEX keeps them to a minimum. MJ will tell you where up front.
