The Tier1 706 Bypass Valve is a direct replacement for the Fleck 11693 automatic control valve bypass. It is specifically engineered to work with Fleck 2510, 2750, and 2850 control valves, allowing you to isolate your water softener or filtration system from the main water supply for service, maintenance, or emergency shutoff without interrupting water flow to the rest of the home. This Tier1 706 bypass features a durable Noryl plastic construction designed for long-term reliability on residential and light commercial systems.

Yes, the Tier1 706 is a direct OEM-equivalent replacement for Fleck part #11693 and fits Fleck 2510, 2750, and 2850 series automatic control valves. It connects using standard 1" threaded inlet/outlet ports and utilizes the same clip-in mounting design as the original Fleck bypass, so no additional adapters or plumbing modifications are needed for a proper retrofit.

No. Unlike cartridge-style filters, the Tier1 706 is a mechanical bypass valve, not a filtration media component, so it has no micron rating, no NSF/ANSI filtration certification, and no gallon or month-based replacement schedule. It is designed to last the lifetime of your softener or filter system under normal operating conditions (up to 125 psi and 100°F). Routine inspection of the internal O-rings every 3–5 years is recommended to ensure a leak-free seal.

Installation is straightforward: shut off the main water supply, relieve system pressure, and remove the existing 11693 bypass by pulling the two retaining clips from the rear of the Fleck control valve. Slide the new Tier1 706 bypass into position, ensuring the O-rings are lubricated with silicone grease, and re-insert the clips. Reconnect your 1" plumbing to the inlet and outlet ports, then slowly restore water pressure and check for leaks. Always refer to your Fleck control valve manual for model-specific guidance.

The Tier1 706 uses a simple push-pull red handle mechanism. Push the handle fully IN to place the system in "Service" mode, allowing water to flow through your softener or filter. Pull the handle fully OUT to engage "Bypass" mode, which routes water around the system—ideal for maintenance, resin replacement, or when you want untreated water (such as for outdoor irrigation). The valve provides a positive tactile stop in each position to confirm proper engagement.
