Plumbing in Detroit: what locals should know
Water quality
The water in Detroit is on the harder side. You may notice mineral spots on fixtures. For water heaters, this means flushing the tank annually is essential to prevent sediment buildup.
Freeze risk
Frozen and burst pipes are a real threat in Detroit. Ensure pipes in unheated areas are insulated with foam sleeves, and consider heat tape for vulnerable runs. A single burst pipe can cause $5,000+ in water damage.
Material recommendation
For Detroit homes, PEX is the go-to repiping material. Its flexibility means it handles freeze-thaw cycles better than copper or CPVC. It's also faster to install, reducing labor costs.
Local tip
Older homes in Detroit (pre-1970) often have galvanized or cast iron drain pipes that deteriorate over decades. A camera inspection ($150-300) can reveal hidden corrosion before it causes a major leak or backup.
