Queens' median house dates to 1935. Most were plumbed in galvanized steel, a pipe with a published working life of roughly 40 to 60 years. “Every 2.31 feet of rise costs one psi. A brownstone's top-floor shower starts 17 psi down before rust narrows the pipe.” NYC water is soft and chemically aggressive: DEP's annual water quality report puts its average Langelier index at −2.21, which means it dissolves metal rather than coating it. Old galvanized pipe rusts shut from the inside, and the house shows it as brown water, a weak top-floor shower and leaks that arrive one after another.

A copper repipe of a New York City house typically costs $12,000 to $35,000, depending on bathrooms, stories and wall type. A co-op or condo apartment typically costs $3,000 to $8,000. The DOB permit fee for a 1–3 family house starts at $130. See the [full NYC repiping cost answer](https://nycrepipe.com/answers/repiping-cost-nyc/) for sources. Is PEX allowed for repiping in NYC? No. Table 605.4 of the 2022 NYC Plumbing Code lists brass, copper and copper-alloy tubing (Types K and L), ductile iron and stainless steel for water distribution. PEX and CPVC aren't on it, so NYC repipes are done in copper. Removable push-fit fittings are also prohibited. [More on copper vs PEX](https://nycrepipe.com/answers/copper-vs-pex-nyc/). Do I need a permit to repipe in NYC? Yes. Replacing a building's water supply piping is filed in DOB NOW by a NYC Licensed Master Plumber, usually as a Limited Alteration Application. Very short repairs can fall under DOB's ordinary plumbing work rules, but a repipe can't. Unpermitted work carries penalties starting at $520. [How the permit works](https://nycrepipe.com/answers/repiping-permit-nyc/). How do you find a hidden leak without tearing up walls? By narrowing it down first. Each branch is shut off and the system pressure-tested to show which line is losing pressure. Then moisture readings and the building's pipe layout point to where that line runs. Openings go in last, sized and placed for the repair, so a hidden leak usually needs one small opening, not a demolition. Does homeowners insurance pay for repiping? Usually not for the pipe itself. Homeowners policies generally cover sudden, accidental water damage from a burst or leak, not replacing pipe that wore out over time. The resulting ceiling, floor and wall damage is often covered; the repipe is treated as maintenance. [Insurance and repiping](https://nycrepipe.com/answers/is-repiping-covered-by-insurance/). How long does a repipe take, and will I have water? An apartment repipe typically takes a few days, and a 1–3 family house about five to ten working days, with plaster restoration and the DOB sign-off after. New copper is run alongside the old pipe and switched over section by section, so the house is normally back on water at the end of each working day. Get a written price on your leak or repipe.
