TheMiLiO Upgraded Instant Hot Water Recirculation Kit for Watts 0955805 & Grundfos 595916 – Programmable Timer with 2 Brass Sensor Valves

Experience faster hot water with TheMiLiO’s upgraded instant hot water recirculation kit, designed to replace Watts 0955805 and Grundfos 595916 systems. It combines two premium brass 595926 sensor valves, a programmable timer, and a DIY-friendly footprint to deliver on-demand warmth to faucets and showers. This kit is not designed for tankless water heaters, but it is optimized for residential tank-style systems that want quicker hot water reach without wasting water.

Overview

This system aims to move hot water to fixtures more rapidly by coordinating dual sensor valves in parallel. With upgraded valve sets and precise control, you may experience shorter wait times at multiple outlets—especially in larger homes or busy mornings.

What’s included

• Stainless steel recirculation pump
• Two WP596816 sensor valve kits (each includes one 595926 sensor valve, two 12-inch supply lines, two adapters)
• Two additional WP596816 kits, totaling two valves, four supply lines, and four adapters
• 10 ft power cord, valve mounting screws, and rubber washers

How it works

When hot water lines cool, the sensor valves activate and push cooler water back toward the heater. The valves close as the line warms to about 98°F, enabling on-demand hot water at the tap without unnecessary runoff.

Programmable timer

• 24-hour dial with quarter-hour increments
• AM/PM indications for easy daily scheduling

Sync the timer with the dual valve setup to optimize circulation during peak usage, such as mornings and after work, while maintaining flexibility for varied routines.

Performance & savings

• Typical hot water delivery can reach fixtures faster, potentially cutting wait times to around 15 seconds in suitable layouts
• Reduces cold-water runoff and water waste, with potential yearly savings in larger homes
• Designed for residential tank water heaters, expanding comfort across multiple fixtures without complicated wiring

Results depend on your home’s plumbing and usage. The kit emphasizes reliable operation, straightforward maintenance, and long-term convenience.

Installation & compatibility

Operating at 120V, the system installs into existing plumbing without a dedicated return line or extra under-sink electrical work. It’s a DIY-friendly upgrade that delivers quiet, efficient operation and requires no ongoing maintenance.
