## What starts a repipe in Park Ridge

### A PEX quote for a Park Ridge address

The City's code text lists cross-linked polyethylene among the materials water distribution piping may not use. A PEX price here is a reason to ask how it would pass inspection.

### Galvanized in a post-war house

Half of Park Ridge's housing was built from 1940 to 1969. Where steel supply pipe from those years is still in place, it narrows from the inside and the far fixtures feel it first.

### A lead service line notice

The City is inventorying service lines and has notified owners with lead lines. Its stated rule is that every lead service in Park Ridge must be replaced by 2044.

### Gray plastic from a past repair

Polybutylene and CPVC are on the City's list of barred water distribution materials. Where a past repair used either, a repipe replaces it with copper.

## Services in Park Ridge

### Copper repiping

Copper repiping replaces water supply piping in tube of the weight the design and local code call for, joined by an approved method and supported so it can move as it heats.

### Whole-house repiping

Whole-house repiping replaces every hot and cold supply line from the main shutoff to the fixtures in the material the local code lists, then pressure tests it before the walls close.

### Galvanized pipe replacement

Galvanized pipe replacement swaps restricted steel supply pipe for copper, with code-listed transitions wherever old pipe stays and a flush after every cutover to clear loosened scale.

### Partial repiping

A partial repipe replaces a defined part of the supply piping, such as one bathroom, one riser, the hot side or one floor, with every joint to the pipe that stays named on the quote.

### Lead service line replacement

A full replacement of the buried water service from the main to the building, with the City's free programs checked first and the new line's basement tie-in planned with the piping it feeds.

### Main shutoff and basement main

Main water shutoff valve replacement covers the valve and the basement main from the meter to the first branch, sized for the building, with a pressure-reducing valve where pressure runs over 80 psi.

Park Ridge’s municipal code names the plastics a repipe here cannot use. Section 15-6-2 says water distribution piping may not be installed using chlorinated polyvinyl chloride (CPVC), cross-linked polyethylene (PEX) or polybutylene, and the next clause says Type L copper shall be used for water distribution above ground.

That text comes from a city-hosted copy of Article 15 dated 2015. The City’s 2024 construction-code update amended the neighboring section 15-6-3 and left 15-6-2 unchanged; 15-6-3 also limits water supply pipe to copper, brass, galvanized steel or cast iron unless the Building Official approves an alternative in writing. So repiping in Park Ridge, IL is planned as copper with the current rule confirmed for each address before work starts. [Chicago Lake Repiping](https://chicagolakerepiping.com/) offers and manages [copper repiping](https://chicagolakerepiping.com/copper-repiping/), [galvanized pipe replacement](https://chicagolakerepiping.com/galvanized-pipe-replacement/) and [main shutoff replacement](https://chicagolakerepiping.com/main-water-line-shutoff-replacement/) in Park Ridge, with the work done by licensed and insured plumbing contractors registered with the City.

## What section 15-6-2 says

Park Ridge adopts the Illinois State Plumbing Code, the 2014 edition and future revisions, by reference in Article 15, Chapter 6 of its Municipal Code. Section 15-6-2, Plumbing Materials, Use and Restrictions, then narrows the state’s list. Its clause C bars CPVC, PEX and polybutylene for water distribution piping. Clause D says Type L copper shall be used for water distribution above ground only, and clause F lets Type K be used above or below ground. Section 15-6-3 adds that the water supply pipe from the main to the building is copper or brass, with other materials prohibited unless the Building Official approves an alternative, and sets a minimum 1-inch water service from the curb.

The difference from the state table is the point. A few miles east, [Skokie](https://chicagolakerepiping.com/service-areas/skokie/) enforces the state code without local amendments, and there PEX is a code-legal choice. In Park Ridge the local section governs, so a quote that offers PEX for a Park Ridge address is a quote to question. The same is true inside Chicago, as the [guide to PEX in Chicago](https://chicagolakerepiping.com/guide/is-pex-allowed-in-chicago/) explains, though for a different code.

## Post-war houses and the pipe inside them

Park Ridge is a city of owner-occupied single-family houses. Census Bureau survey figures compiled by the Chicago Metropolitan Agency for Planning put 71.0% of its 15,573 housing units in detached single-family homes, with 84.8% owner-occupied. Half, 49.9%, were built from 1940 to 1969, 16.2% before 1940, and the median year built is 1960.

Houses from those decades span the change in supply pipe: steel in one house, copper in the next, and in either, a later remodel may have spliced in something else, plastic included. Galvanized steel corrodes from the inside until the bore narrows and flow fades at the furthest fixtures. Copper from the same years may be sound. The [guide to identifying your water pipes](https://chicagolakerepiping.com/guide/how-to-identify-your-water-pipes/) shows how to tell at the meter. Where a past repair used polybutylene or CPVC, that pipe falls on the City’s barred list, and a repipe replaces it with copper. None of this is a finding about a particular house; the basement shows what is there.

## Why a copper-only code changes the quote

Copper is rigid, so every change of direction is a fitting and every fitting inside a finished wall needs an opening. In a house with a finished basement or new drywall upstairs, that sets the number of openings more than the length of pipe does, and the quote should list each one and who closes it. How the copper is joined, soldered or pressed, is part of the written scope and is checked against the code for the address. Copper costs more per foot than PEX, and in Park Ridge that cost is part of every repipe rather than a choice. The [repiping cost guide](https://chicagolakerepiping.com/guide/repiping-cost-chicago/) shows what else sits inside the price.

A [whole-house repipe](https://chicagolakerepiping.com/whole-house-repiping/) replaces every supply line; a [partial repipe](https://chicagolakerepiping.com/partial-repiping/) replaces what has failed and leaves the rest, which the quote must name.

The new copper starts at the meter and main shutoff. If the shutoff is an old valve that no longer closes fully, replacing it first gives the house a working isolation point for the cutover and for every repair after it. A pressure-reducing valve belongs in the scope only where the static pressure reading calls for one, and the reading at the hose bibb on the first visit is what decides it.

## Permits and contractor registration

Article 15 requires a permit for all plumbing installations or alterations, and the City’s permit guidance lists the addition, alteration, replacement or relocation of water supply piping among the work that needs one. Permits are filed with the Building Division of Community Preservation & Development through the City’s Civic Access portal, and a certificate of inspection is required before the new piping is put into use. The permit fee is set by the City and confirmed at filing.

Before a permit is issued, the contractor registers with the City. For plumbing, the registration calls for the Illinois Department of Public Health plumbing contractor registration and a plumber’s license, along with insurance.

## Chicago water and the service line

Park Ridge’s water utility buys treated Lake Michigan water from the City of Chicago, so the water carries Chicago’s corrosion control. The City is inventorying service line materials and has notified residents whose lines are lead, and it states that all lead services in Park Ridge are required to be replaced by 2044. Illinois has required full replacement of a lead line, public and private sides, since January 2023. The service line is a separate job from the pipes inside, and where both are due, [repiping after lead service line replacement](https://chicagolakerepiping.com/guide/repipe-after-lead-service-line-replacement/) explains how to sequence them.

## From the first visit to inspection in Park Ridge

A Park Ridge walk-through notes the service line where it comes through the foundation, then works outward from the meter and main shutoff. Two readings shape the plan: static pressure, taken at a hose bibb, and the flow at the lowest fixture set against the highest. A failing shutoff, a narrow service or a worn fixture cartridge can each pass for corroded pipe, and those readings help sort one from another.

On the job, drywall or plaster comes out in clean rectangles only at the fittings and turns the copper needs, with tiled walls reached from behind where there is access. The copper is pressure tested while the walls are still open, ahead of the City’s inspection. After cutover the lines are flushed, aerator screens cleaned and shutoffs labeled. The quote spells out each opening and who repairs it, any old pipe left behind, the working days and when the water will be off, which is only during cutovers.

## Park Ridge questions

### How much does a copper repipe cost in Park Ridge?

A typical Chicago-area range for repiping a single-family house is $5,000 to $15,000+, and fully finished two- and three-story homes run higher. Park Ridge's code calls for copper, which costs more than PEX as material, so a Park Ridge price is always a copper price. The City's permit fee is set by the Building Division and confirmed when the permit is filed.

### Can a Park Ridge repipe use PEX if the state code allows it?

Not under the City's code text. Park Ridge adopts the Illinois State Plumbing Code, but section 15-6-2 of its Municipal Code adds its own limits: water distribution piping may not be CPVC, cross-linked polyethylene or polybutylene. The City's local section controls, and the current rule is confirmed with the Building Division for the address before work starts.

### Is Type M copper allowed for a repipe in Park Ridge?

The code text names Type L copper for water distribution above ground and allows Type K above or below ground. Type M, the thinner tube, is not named for that use. Because the City-hosted copy of the code is several years old, the accepted copper types are confirmed with the Building Division before the job is priced.

### When do lead service lines have to be replaced in Park Ridge?

The City states that all lead services in Park Ridge are required to be replaced by 2044. It is inventorying service line materials and has notified residents whose lines are lead. Illinois has required full replacement, public and private sides, since January 2023, so a lead line is replaced all the way from the main to the house.

### What does a contractor need before pulling a plumbing permit in Park Ridge?

The City requires contractors to register. For plumbing, the registration asks for the Illinois Department of Public Health plumbing contractor registration and a plumber's license, plus proof of insurance. The permit itself goes through the City's Community Preservation & Development department, and a certificate of inspection is required before the new piping is used.
