As a homeowner in Tacoma or the nearby Fircrest area, staying informed about local building codes isn’t just about avoiding fines—it’s about ensuring the safety, efficiency, and longevity of your home’s plumbing system. In 2025, the Washington State Building Code Council (SBCC) has rolled out several updates to the plumbing code, and these changes directly impact homeowners planning renovations, additions, or even routine plumbing work.
Whether you’re planning to upgrade your water heater or replace aging galvanized pipes, here’s what you need to know about the latest plumbing code updates—and how Einstein Pros Fircrest can help keep your home compliant.
🔍 What Is the Washington State Plumbing Code?
The plumbing code in Washington is based on the Uniform Plumbing Code (UPC), which serves as a model across the U.S. However, the Washington amendments introduce additional safety, environmental, and water-efficiency requirements. These standards are updated every three years, with 2025 bringing new revisions focused on sustainable practices, backflow prevention, and fixture efficiency.

⚠️ Key 2025 Plumbing Code Updates That Affect Tacoma Homes
Here are the most important changes Tacoma and Fircrest homeowners should pay attention to:
1. Water Efficiency Standards
The 2025 code mandates that new plumbing fixtures must meet stricter flow rate requirements:
- Toilets: ≤ 1.28 gallons per flush (down from 1.6)
- Showerheads: ≤ 1.8 gallons per minute
- Faucets: ≤ 1.2 gallons per minute
✅ Why it matters: Lower water usage saves money and aligns with Tacoma’s conservation goals.
2. Backflow Prevention Devices Now Required in More Scenarios
If you’re installing a new irrigation system, pool, or water softener, you’re now required to install backflow preventers to protect Tacoma’s public water supply from contamination.
3. Permitting for DIY Plumbing Is Stricter
While some Tacoma homeowners may attempt DIY repairs, the 2025 code reduces what’s allowed without a licensed plumber and permit. Even common tasks like water heater replacements may now require inspection.
🚫 DIY without a permit? You could be fined or have to tear out work later.

4. Greywater Systems Are Encouraged—with Guidelines
With the push for eco-friendly plumbing, greywater systems (used for landscaping and toilet flushing) are permitted under the 2025 code—but strict rules apply for filtration, storage, and separation from potable water.
🌱 Consider a consultation to explore options if you’re interested in sustainable plumbing solutions.
