Sxtrrdnary RP46074: Delta 13/14 Series Monitor Cartridge – Universal Rough-in Valve Repair Kit

Overview

The Sxtrrdnary RP46074 cartridge assembly offers a versatile upgrade path for many Delta tub/shower setups. Designed as a universal replacement for Monitor rough-in valves, it targets single-handle 13/14 series faucets, providing a practical option that avoids the complexity of full valve replacement.

In everyday use, a reliable valve matters. The RP46074 balances hot and cold inputs with careful calibration, delivering a more predictable shower experience as you adjust the handle. The combination of a brass core and reinforced plastic components emphasizes durability and smooth operation, resisting wear from frequent use and temperature changes.

• Pressure-balanced performance helps keep water temperature steady when supply pressures shift during a shower.
• Durable construction features a brass core with reinforced plastic for long-lasting, leak-resistant operation.
• Tool-free, drop-in installation minimizes downtime and avoids full valve removal; ensure the old valve seat is clean before installing.
