Replacing the flow switch restores flow detection and allows the heater to fire again. FlowTrust uses an OEM-calibrated sensor that opens and closes at the correct flow threshold, eliminating false error codes from a mis-calibrated switch. Compatible with Jacuzzi, Sundance, Sweetwater, and select Caldera spas.\u003c\/li\u003e\n\u003cli\u003eFITS JACUZZI J-SERIES \u0026amp; SUNDANCE 680\/780\/880\/980 – Jacuzzi: J-100, J-200, J-230, J-245, J-270, J-280, J-300, J-320, J-335, J-345, J-355, J-365, J-375, J-400, J-475, J-500, JLX, JLXL.

FlowTrust was designed from the ground up to solve the problems that plague aftermarket flow switches: cracked housings, defective sensors, and missing install hardware.\u003cbr\u003e\nWhy CPVC Changes Everything\u003cbr\u003e\nMost aftermarket flow switches use generic plastic that cracks under heat cycling and chlorine exposure. FlowTrust uses CPVC (chlorinated polyvinyl chloride), the same material used in commercial hot water plumbing. With a minimum wall thickness of 3mm and a one-piece molded body with no glued barbs or epoxy joints, the FlowTrust tee housing handles continuous water temperatures up to 60 degrees Celsius and pressures up to 4 bar (60 PSI) without developing stress cracks.\u003cbr\u003e\nEvery Unit Tested Before It Ships\u003cbr\u003e\nEach FlowTrust flow switch undergoes individual quality inspection before packaging. The pressure test applies 4 bar of water pressure for a full minute, verifying zero leaks and zero cracks. The electrical test confirms the internal sensor correctly detects water flow (closes the circuit when flow is present, opens when flow stops). Units that fail either test do not ship. A dated QC card with inspector code is included in every box.\u003cbr\u003e\nEverything You Need in One Box\u003cbr\u003e\nFlowTrust ships as a complete, ready-to-install assembly: flow switch with pre-wired 60 inch cable and 2-pin curled finger connector, clear CPVC tee housing with directional flow arrow, 3 stainless steel hose clamps, PTFE teflon tape (pre-threaded for convenience plus an extra roll), 5 zip ties for wire harness management, and a printed instruction manual with QR code linking to a step-by-step video installation guide. No extra trips to the hardware store.

It is NOT compatible with models that use square finger connectors, including the 800, 850, and 800 series. Please verify your connector type before ordering.\u003cbr\u003e\nBacked by a 12 Month Warranty\u003cbr\u003e\nRegister your FlowTrust flow switch to activate a 12 month warranty covering leakage and defects with free replacement. If it leaks, we replace it. Scan the QR code inside the box or visit the registration link in your instruction manual.\u003cbr\u003e\nStop paying for service calls. Stop gambling on untested parts. FlowTrust gives you OEM-grade reliability at an aftermarket price, backed by the only individual unit testing program in the category. Your spa deserves a part that was tested before it was packed.
