ZYLJHZ RV Toilet Water Valve Replacement Kit 2-Pack 385311641 — Reinforced ABS, Filters & Flush Balls

ZYLJHZ 2 Pack 385311641 RV Toilet Water Valve Replacement Kit is a complete, upgraded valve and flush hardware kit designed to stop leaks, reduce odors, and restore reliable flushing for compatible RV toilets.

If your RV toilet has a leaking or sticky valve, replacing worn components with the right parts restores performance and prevents waste. This kit from ZYLJHZ bundles two reinforced 385311641 water valves plus essential accessories so you can replace valves on two toilets or keep a spare on hand. The parts are molded from thicker ABS, use ultrasonic welds at joints, and include multiple small components to simplify the swap without hunting for extra fittings.

How will this kit improve my RV toilet’s sealing and odor control?

The upgraded 385311641 valve and the included flush balls and mesh filters tighten seals and block debris that can prevent full closure. Better sealing reduces small leaks and standing wastewater that cause odors.

• Reinforced ABS valve bodies resist cracking and deforming.
• Ultrasonic welding at joints minimizes leak paths.
• Stainless mesh filters capture particles that hinder closure.
• Replacement flush balls ensure a full, water-tight seat.
