Worn-out bypass valve? Still running the old connection yoke? This 3/4" stainless steel bypass is a straight upgrade. It fits most Fleck 5600, 5800, 2510, 9100 and 9000 valves.

HOW TO USE
Swap it in. Service your softener without shutting off the house.
- Shut off the water and relieve the pressure.
- Remove the old bypass valve or connection yoke.
- Install the new 3/4" stainless bypass on your Fleck valve.
- Turn the water back on and check for leaks.
Not sure it fits your valve? Call 1-866-278-4130 before you order.
HOW DOES IT WORK
One valve. Two modes.
- Service mode: Water flows through your softener.
- Bypass mode: Water skips the softener and goes straight to your home.
That means you can do maintenance, repairs or media changes while the water stays on.
