Dometic Lead-Free Water Inlet Valve - Post-2006 Models - Part# 90028
The Dometic lead-free water inlet valve (Part# 90028) is the fresh water entry point for your RV's water system. If your RV was manufactured after 2006, this valve controls water flow from your external source into your onboard tanks. Replacing a faulty inlet valve restores proper water pressure and prevents contamination from older brass components.
Key Features
- Lead-free construction meets post-2006 EPA and NSF standards
- Compatible with Dometic fresh water systems on RVs built 2006 and newer
- Prevents backflow and maintains consistent water pressure
- Direct OEM replacement—no modifications needed
- Durable polymer body resists corrosion in freeze-thaw cycles
- Standard 1/2" connection fits most RV inlet ports

Frequently Asked Questions
- Will this valve fit my 2008 travel trailer?
- Yes. Part# 90028 is designed for Dometic water systems on RVs manufactured from 2006 onward. Verify your current valve uses a 1/2" NPT connection to confirm compatibility.
- What's the difference between this lead-free valve and older brass inlet valves?
- Lead-free valves meet EPA Safe Drinking Water Act standards and prevent lead leaching into your fresh water tank. Older brass valves may contain small amounts of lead, which is why Dometic switched to lead-free designs after 2006.
- How do I know if my inlet valve needs replacement?
- Replace the valve if water pressure drops when connecting to shore, if you notice water leaking around the connection, or if the valve handle becomes stuck. A faulty valve can also allow contaminated water to enter your system.
