Kitec Pipe Replacement
Kitec is a composite pipe, an aluminum layer between inner and outer PEX layers joined with brass fittings, sold from 1995 to 2007 as a cheaper alternative to copper. It sits in homes built, repaired or renovated in that window, unnoticed until an inspector, insurer or buyer names it. The fittings are the story.
This page covers interior Kitec potable supply piping: confirming the material, the whole-system case, the proprietary-fitting problem, and what writes the number. Staging, openings and cutover belong to Whole-House Repiping; a single leaking fitting on unidentified pipe belongs to Pipe Repair until the material is named; polybutylene has its own page, Polybutylene Pipe Replacement. Kitec in radiant or baseboard heating loops is hydronic heating work and routes to a heating contractor. The Pipes & Repiping hub holds the repair-or-replace decision for other materials.
Common Causes
Why the material, not the leak, is the subject:
- High-zinc brass, aggressive water. The Nova Scotia Real Estate Commission's account: the pipe's sizing required fittings from its own manufacturer, IPEX, made with a high zinc content that dezincified in aggressive water conditions, restricting water pressure or failing completely.
- The pipe, on one theory. The same regulator reports pipe disintegrating in Nova Scotia and offers one theory: the hot water system run at too high a temperature; the product was certified to a maximum of 180 F. A theory, not a court finding.
- An allegation, not a verdict. The court record frames the defect as an allegation of possible premature failure; the courts never ruled, and IPEX denied it.
- Insurance and resale pressure. The settlement FAQ records owners required by an insurer or inspector to replace with another system though a leak never occurred; disclosure duties on sale vary by state.
How a Plumber Diagnoses the Problem
How the material is confirmed and the scope drawn:
- Read the pipe where it shows. Where pipe enters walls at the water heater or mechanical room, and under sinks and vanities: the places the settlement notice names. Orange hot and blue cold is typical, but red, gray and black were sold too; proof is print on the pipe and Kitec or KTC on fittings.
- Signs on fittings and pipe. The settlement administrator's first signs: white residue outside a fitting, blackening or bulging of the pipe, usually first near the water heater.
- Material failure or installation failure. The settlement release lists installation faults: nail penetration, a fitting badly attached to a fixture, framing stress, a plumber-supplied pressure reducing valve, aged sealant. Those are repairs; a fitting failing on its own is the material reporting.
- Supply or heating loop. ASTM F1281 covers potable distribution and radiant, baseboard and snow-melt heating, so one house can hold both. Supply is this page; the loop is a heating contractor's.
Service Details & What's Included
Scope, and what writes the number:
- Access and fitting count. The settlement valued repairs by three installation types: open and accessible, behind drywall, in concrete. Still the cost structure; every concealed fitting is an access cut, so count outranks footage.
- Partial or whole. A partial job leaves the same fittings in the walls it did not open; the scope says which stay and why, and puts the identification on paper.
- The transition problem. Kitec took IPEX's own fittings; IPEX listed a purpose-made adaptor kit for joining it to its compression fittings, and the 2021 International Plumbing Code, a model code, has PEX-AL-PEX fittings follow the manufacturer's instructions. Often the cleanest transition is none: Kitec cut out at the manifold and water heater, new pipe from there.
- Permits by locality. Clark County, Nevada issues Re-Pipe (Residential Only) as a simple online permit with no plan review; the City of Las Vegas requires a permit to alter piping inside a wall, ceiling or beneath a floor. Elsewhere, the scope names the rule.
- What stays out. Drains, the service line, gas, fixtures, and Kitec in heating loops. Who patches and who paints is stated in writing.
Frequently Asked Questions
How do I know if I have Kitec plumbing?
Print is proof: a brand name on the pipe (Kitec, PlumbBetter, IPEX AQUA, WarmRite, Kitec XPA, AmbioComfort, XPA, KERR Controls, Plomberie Améliorée) and Kitec or KTC on the fittings. Polybutylene is a different pipe; see Polybutylene Pipe Replacement.
Does all Kitec need replacing, or can it be repaired?
The court record does not say so: the courts never ruled and IPEX denied the defect. The record does say the settlement remedy was replumbing, and the administrator's advice is to replace defective pipe or fittings and monitor the rest. A single fitting can be cut out; failures that keep landing at fittings are the replacement conversation.
What replaces Kitec?
PEX or copper, run new from the manifold or water heater. PEX-AL-PEX as a class is still listed in the 2021 International Plumbing Code (Table 605.4, ASTM F1281); the product line failed in the field, not the class's code status. Replacement brass fittings today are made to dezincification-resistant specifications.
Is the Kitec settlement still open?
No. The settlement was approved in late 2011 and the claim deadline was January 9, 2020. Late claims were barred after March 1, 2021; the one hundred twenty-five million U.S. dollar fund was oversubscribed, so no claimant was made whole, and payments were issued by July 2025. Replacement today is the owner's cost.
Does Kitec in radiant floor heating count?
The same pipe, sold for potable water and for in-floor and baseboard heating, but a heating loop is hydronic work, not this page's; the settlement plan treated replacing radiant heating with another heat source as a remedial cost. Find a hydronic contractor.
