## Questions & Answers

**Q: Any time the pump looses power and reboots when it gets power back does it have to refill all the way to top line for measurement? Or is it a one time**
A: Yes it has to refill to the top sensor so it can recycle, also if water level goes way below sensor when it reboots it will only pump 3 times then red light comes back on so unplug and plug back in so it can pump remainder water to reach level you might have to do this several times( i hope not) usually once is sufficient, hope this helps.

**Q: Can I use it on a 40 gal ?**
A: Yes, it will work fine.

**Q: Will this still work if I put a longer tube on it?**
A: Sure

**Q: How do you install hose clamp on a rimmed tank?**
A: Just rotate it. It will fit.
