1. Improper or Missing Cleanouts
Cleanouts allow access to your drainage system for clearing blockages. The Washington State Plumbing Code requires cleanouts to be installed at specific intervals and accessible locations.
Many older homes in University Place either lack cleanouts entirely or have them installed in inaccessible spots, violating Section 708 of the Washington State Plumbing Code.
Why It Matters:
- Makes clearing clogs difficult or impossible without damaging pipes
- Can increase the cost of repairs
2. Non-Compliant Pipe Materials
Using the wrong pipe materials is another common code issue. For example, many DIY installations use materials like PVC where copper or PEX is required, especially in hot water systems.
Washington State plumbing code (WAC 51-56) clearly specifies which materials are acceptable for potable water, drainage, and vent systems.
Why It Matters:
- Unsafe materials can leach chemicals into drinking water
- Some materials are not rated for high pressure or temperature
- Insurance may deny claims on non-code-compliant installations
3. Improper Venting of Drain Lines
Drainage systems must be vented properly to prevent negative pressure and sewer gas backup. One of the most common violations in University Place is missing or improperly placed vents—especially in DIY bathroom remodels.
According to the code, each fixture must be properly vented (per Chapter 9: Vents of the plumbing code).
Why It Matters:
- Poor venting can lead to slow drainage and sewer gas exposure
- Violates health and sanitation requirements
4. Incorrect Slope of Drain Pipes
Drain pipes need a precise slope (typically 1/4 inch per foot for 3” pipes) to allow wastewater to flow correctly. Too steep or too flat a slope can lead to standing water or solids clogging the system.
This technical requirement is frequently overlooked in DIY work and older homes.
Why It Matters:
- Causes recurring clogs and drainage issues
- Long-term stress on pipe joints may cause leaks
5. Lack of Backflow Prevention Devices
In homes with irrigation systems, hose bibs, or other cross-connections, backflow prevention is required to prevent contaminated water from re-entering your home’s supply.
University Place homes are subject to backflow rules outlined in WAC 246-290-490, enforced by local water districts.
Why It Matters:
- Prevents contamination of the drinking water supply
- Required for homes with sprinkler systems or hot tubs
6. Unpermitted Water Heater Installations
Installing a new water heater without a permit is one of the most overlooked code violations in University Place. The Washington State code requires temperature & pressure relief valves, drain pans, expansion tanks, and seismic strapping—especially in Pierce County’s seismic zone.
Many homeowners install heaters without pulling permits or hiring a licensed plumber, risking safety and code compliance.
Why It Matters:
- Major safety risk (explosion hazard from pressure build-up)
- No permit = no inspection = no resale value
7. Improper Trap Configurations
Double traps, S-traps, and improperly vented traps are a common sight in older homes or DIY remodels. However, plumbing code strictly prohibits these configurations in favor of P-traps with proper venting.
See Section 1002 of the Washington code for trap rules.
Why It Matters:
- Can lead to foul odors and sewer gas entering the home
- May void homeowners insurance in case of water damage
8. Hose Bibbs Without Vacuum Breakers
In University Place, outdoor faucets (hose bibbs) are required to have vacuum breakers to prevent back-siphonageinto the home’s water supply.
This is one of the easiest yet most overlooked violations.
Why It Matters:
- Prevents lawn chemicals or bacteria from contaminating your water
- Cost-effective to fix but critical for safety
