Review: Good product - This product gave me no issues. Been in service for several months now. No complaints here.
Review: Flow Switch for Tankless water heater for CA title 24 compliance. - This product is used on my tank-less water heater to activate the re-circulation pump. I just momentary turn on than off any faucet in my house for a second and the flow switch activates the re-circulation pump. This is needed to be in compliance with title 24 of CA code. A re-circulation pump is not allowed to be on a timer or on full time. Instead the code requires an activation button located near each faucets. This works better as you don't needed multiple buttons! There is a plastic flow switch but its max flow rate is below the 11gpm of my tank-less. This has a higher flow rate. Note: This flow switch has BSP threads you will need to use BSP to NPT adapters.

## Questions & Answers

**Q: If i have a gravity feed water line running through this can i make this device turn on a pump?  12V?**
A: Hello, it work with 12V, if the gravity is higher than 0.02MPa, it can turn on a pump.

**Q: Another question what is the ID of the water passage**
A: Not sure of the exact measurement but it was pretty small. Also, if you intend on using this with anything more than about 12 Volts and 500 mA I would look elsewhere as this thing will not perform anywhere near the quoted specs. Even worse after it failed on the first use, it failed in the on poition.

**Q: I want a 1 inch digiten fs-c0 1" bsp male thread water flow switch 0-2a/ 0-220v(ac or dc). do you have?**
A: Sorry. The ones I have I am using in my home system.

**Q: I wondering how much this flow switch restricts water flow? Some of the 3/4 inch flow switches I have seen have very restricted water flow.**
A: I’ve not noticed any change in flow since I installed it on the hot water line for our bathtub/shower.
