Wairool RP46074 Shower Valve Cartridge Assembly for 13/14 Series – Single-Handle Universal Repair

Overview

The Wairool RP46074 shower valve cartridge assembly offers a focused repair option for single-handle showers and tubs in the 13/14 series. Rather than replacing an entire faucet, this compact kit targets the cartridge—the heart of the control—so you can restore smooth, reliable operation with less downtime and mess. Expect a more controlled shower experience as the component handles the balance of cold and hot water with precision.

Why RP46074 stands out

• Fits all single-handle 13/14 series showers and tubs; not compatible with 1300/1400 series from older generations.
• Pressure balance design helps maintain a steady temperature, reducing abrupt changes during showers.
• Plastic core construction minimizes corrosion and wear, supporting longer service life and water efficiency.
• Includes rough-in components R10000, R1100, R1800, and R2200 for compatibility with common valve bodies.

Ease of installation

• Installation is straightforward: remove contaminants around the old cartridge before inserting the new one.
• You can repair the valve without replacing the entire faucet, saving time and potential plumbing disruption.
• Follow basic hand tools and the kit’s guidance to ensure a secure, leak-free seal.

Real-world use and benefits

In active households, a well-balanced cartridge can contribute to a calmer shower routine, where temperature remains within a predictable range and water usage stays efficient. While results vary by plumbing setup, the RP46074 provides a targeted upgrade that centers on reliability and ease of maintenance, offering a practical option for ongoing faucet care.

Note: Benefits described here are possibilities based on design features and typical household use. This replacement focuses on restoring function through targeted cartridge repair rather than a full faucet replacement.

Specifications and compatibility

Designed for single-handle 13/14 series faucets, the RP46074 is a versatile repair solution intended for newer-generation valve bodies. Check compatibility to ensure it aligns with your current system, and consult your installation guide for best results.
