  • Perfect Fit for watts & grundfos Pumps:This WP596816 sensor valve kit is a direct replacement for your old watts or grundfos parts. It works flawlessly with watts premier 500800/500805 recirculating pumps and grundfos up15-10SU7P/TLC Comfort Series 1/25 HP circulators—no need to worry about compatibility issues. Just install it under the sink at the fixture furthest from your water heater (the key spot for recirculation systems) and you’re good to go.
  • Smart Auto-Operation for Instant Hot Water:Tired of waiting for hot water? This valve does the work for you: it automatically opens when your hot line cools down, sending cold water back to the heater to reheat. Once the pipe hits 98°F (ideal for handwashing or showers), it shuts off—so you get hot water instantly at every tap. No more standing around, no more wasted water.
  • Save Water & Cut Energy Bills:Stop letting cold water run down the drain! This bypass valve eliminates that waste, slashing your water bill and reducing the energy your heater uses to reheat stagnant water. Pair it with a timer (optional) to limit flow even more—you’ll see the savings add up fast. It’s the ultimate upgrade for a greener, more efficient home.
  • Durable, Leak-Proof Construction:Made from high-performance PPS plastic with 50% glass fiber, this valve is built to handle hot water pressure and temperature swings. It resists corrosion, won’t warp, and features a strong threaded design to prevent leaks—common problems with cheaper valves. Rest easy knowing it’ll last for years without issues.
  • Quick, No-Hassle Installation:You don’t need a plumber! This kit comes with everything you need: 2x 12-inch supply lines, 2x 1/2" to 3/8" reducers, and mounting screws. Just follow a quick YouTube tutorial, and you’ll have it installed under your sink in minutes. Note: It’s for indoor use only with standard tank water heaters—not for tankless or outdoor setups.
