Product Details
✓385311641 Valve Replacement Part: This replacement valve is designed for 300/310/320/321/311/301 series pedal-flush toilets. Resists freezing and cracks, even in sub-zero temps, solving water waste and leakage issues. Rigorously tested for reliability, essential items for your RV travel
✓Replace Leak Valve Easily: Fix leak, inefficient valves in minutes-no professional help needed. The 385311641 valve is designed for hassle-free DIY installation. With basic tools, align the valve, secure with included parts, and tighten gently. It disassembles easily later without damage and restores optimal flushing quickly, avoiding costly water damage
✓Avoid Over-Tightening: Protect threads by not over-tightening when connecting to water pipes. The valve's precision threads enhance strength-over-tightening can strip them, causing leaks. A firm, snug fit suffices to maintain the leak-proof seal, ensuring durability and proper function
✓Secure Pipes with Fasteners: RV movement can loosen pipes-use the included hose clamp and screws to secure connections. This prevents shifting or detachment during travel, eliminating leaks and water waste. Ensure a stable and sealed connection
✓Small Valve, Big Role: During your RV trip, toilet water valve leak is a troublesome and tricky problem, greatly affecting your RV travel experience. This small and portable 385311641 valve is used for maintenance as a backup to quickly solve the leakage problem and ensure a relaxing RV trip for you
✓Compatible with Dometic Pedal-Flush Series: Specifically engineered as a direct replacement for Dometic 300 series pedal-flush toilets, ensuring proper fit and function for models 300, 310, 320, 321, 311, and 301
