Steel pipe coated in zinc was standard for decades. In some Syracuse area houses it is still in the walls, and it is aging.
Galvanized pipe is steel with a zinc coating. The coating slowly wears off inside the pipe, the steel rusts, and mineral scale builds on top. Over decades the opening narrows and rust sheds into the water.
What it looks like in the house
- Brown or orange water from cold taps, especially first thing in the morning.
- Pressure that is fine at the basement and weak upstairs.
- Pinhole leaks and rust stains at threaded joints.
- Flow that drops when two fixtures run at once.
Is brown water always the pipes
No. Rust stirred up in the supplier's main after a break or maintenance work can reach your tap. Onondaga County Water Authority advises running one cold faucet for 10 to 15 minutes until it clears, never the hot first, so the dirty water stays out of your tank. Remove the screens or aerators from the faucet you flush. After a main break or maintenance, run a cold tap for 15 to 30 minutes. If the water keeps running brown with no main work nearby, suspect your own pipe.
Where the steel is concentrated
State inventory records show galvanized service lines in several older villages and towns. The Town of Salina has 905 galvanized lines flagged for replacement out of 12,050 records. The Village of Liverpool has 196 of 1,193 records, about 16 percent. North Syracuse shows 404 of 2,538 records, also about 16 percent, and the Village of Camillus is near 16 percent while the surrounding town is near one percent. In many of those records the utility side is already copper, which leaves the owner's steel as the last piece of the old line.
Service line versus house piping
The inventory counts galvanized service lines, the buried pipe from the street. The pipes inside the walls may be steel as well. A house can have both. Replacing the service line and leaving steel inside means the new pipe feeds old, narrow runs. A good contractor will look at both.
Repiping options
Copper has long service history and is rigid, and PEX is flexible, goes in with fewer joints and often means less wall opening. Both are used in houses here. Ask which one the quote assumes and why.
The hard water factor
OCWA's water ranges from 115 to 190 parts per million of hardness, which it calls moderately hard. The city's Skaneateles Lake supply measures 127 milligrams per liter. Hardness is the mineral content that leaves scale inside pipes and heaters.
Permits and who does the work
A new or changed plumbing system needs a county permit, and a homeowner permit covers only inside work on an owner occupied single family house. Newly installed lines, and altered ones, must be disinfected before use under the county requirements. Ask the contractor how that step is handled, and who patches the walls.
What a repipe disrupts
Plan for the water to be off while runs are swapped (ask the contractor how long), small access openings in plaster or drywall and a flush of the new lines afterward. Bathrooms and kitchens are the busiest runs, so the work can be staged. Ask for a written scope that names which fixtures are included.
Deciding whether to wait
Steel does not fail on a schedule. If water is clear and pressure is good, you may have years left. If you are renovating a bathroom or kitchen with the walls open, that is the cheapest moment to replace the runs in that wall.
