## Questions & Answers

**Q: Can this float be used to either fill or empty a tank?**
A: Yes. The Waterboss Float Switch supports both filling and emptying. You simply wire it according to your desired function. There’s no need to buy a separate model.

**Q: Do I need a counterweight for installation?**
A: No, not usually. The float includes an adjustable tether, which is enough for most installs. A counterweight is included for setups where tethering isn’t possible or precise positioning is needed.

**Q: What voltages does it support?**
A: Water Boss works with both 120V and 220V AC, and also supports 12V or 24V DC circuits — up to 13.3A non-continuous or 12A continuous.

**Q: Can I connect this directly to a pump?**
A: Yes — the float can directly control pumps up to ½ HP or be used as a low-voltage signal switch in control panels.

**Q: How long will it last?**
A: Inside every Water Boss is a micro switch rated for over 100,000 cycles, meaning years of dependable operation.
