Customer Questions & Answers
-
Question:
What materials is this flow sensor made of?
Answer: This flow sensor switch is made of brass. -
Question:
What does this flow sensor do?
Answer: It is a safety device that shuts off the current to devices when it senses no water flow. -
Question:
Do I need to add a relay when connecting the load?
Answer: Yes, please add a relay when connecting the load. -
Question:
Am I able to connect a 12 Volt water pump directly to this flow switch?
Answer: No, it needs to add a relay board. It cannot be directly connected to the circuit. -
Question:
Can I get a replacement for the reed switch?
Answer: Please connect a relay before use. Please contact the customer service email for other questions at [email protected]. -
Question:
Is this product lead-free?
Answer: I suspect it is not lead-free, because it does not have any designation for its lead content. Keep in mind that if this is used for regulation of intake to a hot water system, the entirety of that plumbing system is full of lead. I got this as a replacement for a very-leaded part (colored silver) made by NTI. -
Question:
What is a safe heat range for this? Is there a range limit?
Answer: I have mine on the hot water heater line. I had it up to 120 degrees Fahrenheit with no issues. I did have to replace mine because it isn’t designed to handle 120 V AC switching. Mine burned out and got stuck on. So I wired it into a low-voltage relay which would switch on the 120 V AC to my circulation pump.
