Frequently Asked Questions
Will this fit US standard NPT pipe threads without leaking?
Yes, 100%. Simply apply 4–5 wraps of the included FREE PTFE tape around the threads for a perfect watertight seal on US NPT connections.
Which model should I choose?
Choose Model A/C (Straight) if your water pipe enters from the top. Choose Model B/D (Elbow) if your pipe comes through the side wall. Select 20 mm (1/2") for standard household hoses/pipes, or 25 mm (3/4") for high-flow agricultural lines.
Does it need electricity, batteries or solar power?
No. The valve uses water pressure and mechanical buoyancy to open and close automatically.
What water pressure does it support?
The product is specified for approximately 10-150 PSI operating pressure.
Is 304 stainless steel suitable for livestock water?
Absolutely. 304 stainless steel is food-grade, non-toxic, and lead-free. It will never rust or contaminate drinking water for animals or garden crops.
