What IPEX just published
IPEX released its first-ever Environmental Product Declarations in July 2025. The initial set covers PVC Schedule 40 piping systems for DWV applications and is scoped as a system EPD that includes both pipe and common fittings in a representative design scenario. The declared design basis is 1,000 linear feet of rigid PVC pipe with 234 fittings and a 50-year reference service life, aligned to plumbing use in North America.
Program operator and rulebook
The EPDs are verified and published through UL Solutions. The technical rulebook they cite is the Product Category Rules for Rigid and Flexible Building Piping Systems in North America (PCR‑1002). This keeps the comparison set clean for apples-to-apples DWV evaluations across brands.
How many and how broad
There are three current IPEX declarations in this first wave, each labeled PVC Schedule 40 Piping System and mapped to MasterFormat 22 10 00. All share the same July 2025 issue timing and are current through July 2030. Scope notes point to multiple diameters typical of DWV and clarify that fittings are included, which is useful since project teams install systems, not orphaned sticks of pipe.
LCA developer credits
The public record for these documents does not name a third-party LCA consultant. If that changes, we will update this note so teams can understand who stood behind the modeling and verification. Not listing a developer is acceptable as long as verification is clear and complete.
Work for IPEX or competing against them?

Why it matters commercially
On jobs that require product‑specific, third‑party verified EPDs, products without a declaration are modeled with conservative defaults. That can make otherwise comparable products look heavier on carbon, and they get value‑engineered out while teams race the schedule. A current DWV system EPD from IPEX gives estimators a clean submittal with fewer back‑and‑forths, and it keeps PVC in play without forcing a price‑only decision.
The competitive picture in piping
Under the North American piping PCR cited above, current coverage is still thin. IPEX now represents most of the up‑to‑date entries for rigid PVC DWV systems, with one additional current entry visible from another producer under the same PCR. Commonly encountered DWV competitors in North America include Charlotte Pipe, JM Eagle, and Westlake Pipe & Fittings. We did not see current listings for those brands under this exact PCR at the time of writing, which suggests IPEX just moved from catching up to setting the pace in Schedule 40 DWV transparency.
What spec teams should expect inside the docs
- A clear declared unit and system boundary appropriate for installation reality (pipes plus fittings)
- A50-year reference service life for use-phase modeling consistency
- A UL-verified dataset suitable for LEED v5 materials documentation and owner ESG reporting
If your project templates rely on Division 22 submittal bundles, keeping pipe and fittings under one EPD simplifies internal reviews and avoids duplicate attachments.
Quick background on IPEX
IPEX manufactures thermoplastic piping systems used across plumbing, mechanical, industrial, municipal, and electrical markets in North America. That footprint means a single DWV system EPD can ripple across many bids, from core-and-shell multifamily to healthcare renovations where documentation discipline is strict.
Are the new EPDs on IPEX’s website yet
We looked for a dedicated sustainability or EPD page on ipexna.com and could not find the new documents. If they are live in a subpage or distributor portal, they were not readily discoverable. Visibility matters because estimators copy what they can grab fast, so posting a simple “Environmental Product Declarations” page and linking each PDF is an easy win for pipeline velocity. Small change, outsized visiblity.
Takeaway for manufacturers watching this move
First EPDs do not need to boil the ocean. Start with the workhorse systems that touch the most bids and align to the PCR competitors will use. Keep the scope practical so submittals mirror how products are actually installed. Then build from there. IPEX just entered the transparency arena with DWV system coverage that helps specifiers say yes, and that is where momentum starts.
