Sxtrrdnary RP46074: Delta 13/14 Series Monitor Cartridge Repair Kit (RP22734 Bonnet Nut)

Upgrade your Delta 13/14 tub and shower with a reliable RP46074 cartridge

Designed as a universal repair solution, the RP46074 cartridge assembly fits many rough-in valves and most single-handle Delta 13/14 series faucets. It provides a practical, plug-and-play replacement option that can revitalize performance without pulling the entire valve. This kit is ideal for homeowners tackling a bathroom refresh or a quick fix during busy repairs, offering a clean, less disruptive path to better reliability.

Key benefits come from its balanced design. The pressure balanced performance helps maintain a steady water temperature, typically within 3.6 Fahrenheit (2 Celsius), reducing abrupt hot or cold shifts. This makes showers more predictable, especially in mixed-use households where child safety and comfort matter. While it cannot guarantee uniform results in every situation, it presents a practical improvement over worn components.

Durable, long-lasting construction

• Brass core with reinforced plastic provides rigidity and wear resistance for daily use.
• Max hot water flow is limited to help prevent scalding and enhance safety in the shower.

Easy, tool-free installation and a budget-friendly repair

The kit is designed for direct drop-in replacement with no special tools required. You will want to clean the old valve seat before installing for best results, which helps ensure a snug seal and smoother operation.

• Skip costly valve replacement — this assembly can address common leaks and temperature issues at a fraction of the price.
• Includes RP22734 bonnet nut for a complete retrofit and a tidy, dependable finish.

What you get and how to use it

Compatible with Delta rough-in valve models such as R10000, R1100, R1800, R2200, and similar kits, covering most 13/14 series single-handle configurations. Note the exclusion for 1300/1400 series.

Real-life scenarios include refreshing a dripping cartridge after years of use, improving temperature control in a busy family bathroom, or upgrading worn components to reduce the risk of sudden temperature shifts. The end result is a quieter, steadier shower experience that feels like a thoughtful, practical refresh, backed by durable construction designed for daily use.
