RWC at a glance: products and EPD coverage
Reliance Worldwide Corporation sits behind some of the most familiar plumbing names in North America. Think push‑to‑connect fittings, PRVs, firestop sleeves, and OEM push‑fit tech. The portfolio is broad and the brands are strong. The open question for spec‑driven projects is simple. Where are the Environmental Product Declarations, and how quickly could RWC close the gap to win more specs without price wars?


Who RWC is and what they sell
RWC is a global plumbing group best known in the U.S. for SharkBite push‑to‑connect systems, Cash Acme control valves, HoldRite engineered supports and firestop, John Guest OEM push‑fit, and Eastman and EZ‑FLO supply lines. From meter to fixture, they cover rough‑in to finish across residential, light commercial, and some industrial settings (RWC brand pages).
Product range in plain English
Across these brands, RWC participates in several product categories: plastic and brass push‑fit fittings for PEX, copper and CPVC, PEX system components, water pressure and temperature control valves, pipe supports and acoustic isolation, cast‑in firestop devices, drains, appliance connectors, and stop valves. The combined catalog runs to hundreds of SKUs, with dozens per sub‑category in plumbing distribution. That breadth creates real optionality in specs, and real room for EPD coverage to work harder.
EPD status today
As of December 20, 2025, we could not locate published, product‑specific EPDs for SharkBite, Cash Acme, John Guest, HoldRite, Eastman, or EZ‑FLO in the major public EPD libraries checked. That does not mean they are not in development. It does mean specifiers looking for product‑specific declarations will often shortlist competitors who already publish them.
The competitive picture
Several direct and adjacent rivals publish EPDs for comparable plumbing systems and components.
- Viega lists EPDs for ProPress copper press fittings in its download center, which specifiers routinely reference for submittals (Viega, 2025).
- LK Systems publishes an EPD for PushFit fittings and manifolds that is valid through October 2027, a clear signal to buyers that product data is transparent and current (EPD International, 2025).
- Uponor has EPDs for pre‑insulated PEX systems and bio‑based PEX offerings in Europe, further normalizing EPDs in hydronic and domestic water applications (EPD Hub, 2025).
- Trade associations are adding momentum. The Plastic Pipe and Fittings Association announced 22 new industry‑average EPDs in December 2025, raising the baseline for transparency in premise plumbing (PPFA, 2025).
Why this matters commercially
On projects pursuing LEED v5 and on owners’ internal carbon policies, teams prefer product‑specific EPDs to avoid conservative default factors that can penalize selections. Without an EPD, even a well‑liked product can get sidelined for a similar system that carries a verified declaration. That turns many bids into commodity fights. With an EPD, the same product is easier to defend on submittals, easier to keep in the spec, and less likely to be swapped late in the game.
Likely high‑impact starters for RWC
Two obvious places to start are also two of RWC’s most visible lines.
- SharkBite EvoPEX push‑to‑connect PEX fittings and valves. These show up everywhere in residential new build and repipe. Competitors with published EPDs in fittings or press systems get a head start when an owner asks for declarations.
- Cash Acme pressure‑reducing valves, mixing valves, and T&P relief valves. PRVs and TMVs are core mechanical safety components that specifiers document heavily. An EPD here would travel across education, healthcare, multifamily and light commercial with immediate ROI.
Where competitors collide on real jobs
Specs frequently allow cross‑families when performance is equivalent. That can put EvoPEX up against copper press systems like Viega ProPress on multifamily cores, or OEM push‑fit like John Guest against other cartridge or push‑fit providers in beverage and water quality equipment. When one side puts an EPD on the table and the other does not, the EPD becomes the tie‑breaker that nudges selection. It is subtle, but it moves volume.
Rough scope of work to close the gap
- Prioritize one PCR and one program operator per product family to avoid churn. For many fittings and valves, the general construction products PCR under EN 15804 works as the rulebook.
- Start with a plant and a high runner. One facility, one material family, one declaration. Expand SKUs via ranges or group EPDs when the PCR allows it.
- Build a repeatable data spine. Utilities, alloys or polymers, scrap and regrind rates, packaging, and transport in a consistent template. That makes renewals painless.
- Publish where specifiers actually look. Owners and AORs are comfortable with EPD International and operator download centers. Make the PDF easy to find from every product page.
A note on sustainability communications
RWC highlights a 42 percent Scope 1 and 2 reduction target achieved ahead of its 2030 goal, and a net‑zero by 2050 aspiration. That is credible momentum to anchor product‑level declarations once published (RWC Sustainability, 2025).
Competitor set to watch
In plumbing packages for residential and light commercial, RWC frequently sees Viega, Uponor, NIBCO, Mueller Streamline, LK Systems, and regional PP‑R and PE suppliers on the same project rosters. Some are like‑kind, others are substitutable by application. The common thread is rising availability of EPDs that make submittals cleaner and procurement simpler.
Bottom line for manufacturers reading this
If a portfolio looks like RWC’s, the EPD business case is strongest where volumes are high and specs are tight. Start with one flagship fitting line and one valve family, then scale. The lift is mostly data wrangling. Do that well and the declarations pay for themselves the first time a project team keeps your product in the spec. And yes, it really can be that fast when the collection workflow is set up right, not messy or slow at all. If anything, waiting costs more. It’s time to move alot faster.
Frequently Asked Questions
Does RWC publish a sustainability report and climate targets manufacturers can reference when aligning product EPDs to corporate goals?
Yes. RWC publishes a sustainability page and reports, noting a 42% Scope 1 and 2 reduction target achieved ahead of its 2030 goal and a net‑zero by 2050 aspiration (RWC Sustainability, 2025).
Which competitor plumbing systems currently advertise EPDs that may influence specs against push‑fit or press‑fit offerings?
Examples include Viega’s ProPress system with EPDs available in its download center (Viega, 2025) and LK Systems’ PushFit EPD valid through October 2027 (EPD International, 2025). Trade associations like PPFA also publish industry‑average EPDs that shift baselines (PPFA, 2025).
If starting from zero, where should a plumbing manufacturer focus first for EPDs?
Pick one high‑runner family per plant, confirm an applicable PCR, and build a clean data model for materials, energy, scrap, packaging, and transport. Use group or range EPDs where the PCR permits to maximize SKU coverage with minimal duplication. Publish through a widely recognized operator so submittals are painless for design teams.
