## Questions & Answers

**Q: What tubing size will fit? 3/16"?**
A: I was able to use 1/4” clear plastic tubing from the hardware store to fit this pump

**Q: how much gph?**
A: 24-28.8 gph

**Q: What is the maximum current draw for this pump?**
A: Well I hooked it up to a 25v DC power supply/amp meter and at 6v no load was 150ma with load it was 210ma. The highest voltage attained was 8.8v no load was 220ma with load the maximum voltage was 8.6v and 340ma. Hope this helps. Not sure why it wouldn't hit 12 volts, I run it on a 12v motorcycle battery.

**Q: Is the flow reversible when reversing the poles?**
A: No, it pumps in the same direction even if poles are reversed.

### ⭐⭐⭐⭐⭐ FANTASTIC!
*by M***T on January 15, 2019*

This pump worked PERFECTLY right out of the box. I am using it with an arduino for a bit of DIY watering system. I've purchased other pumps in the past that did the work but seemed to struggle. This pump has plenty of push, I have 3/8"OD piping connected to a small 1/4"OD tube running to a pitcher of water. It transfers the water with ease and is actually extremely quiet! I purchased 2 for prototyping and experimenting with them, but they have me sold. I'll be ordering more extremely soon. From other reviews i've seen, they say it doesn't self prime. Mine had no issue with priming whatsoever. I left plenty of air in the tubing while initially connecting it and it deals with it with ease.
