## Questions & Answers

**Q: Lousy house pressure, if I connect outlet of garden faucet to inlet of this pump will I get better outlet pressure to drive an impact type sprinkler?**
A: No it will not do anything for you... This is also 12V not 110 so maybe you should look into your houses old plumbing or contact city about your low water pressure

**Q: Automatic shut off?**
A: Yes it has a pressure switch that shuts it off when you shut the flow of water off

**Q: What is the power usage for this motor? Amp hours would be best, but pretty much any measure would be helpful.**
A: This is a 12V DC water pressure pump. The max amperage draw is 7.5 Amps. All technical specifications on the pump can be found here: http://seaflo.com/en-us/product/detail/609.html

**Q: What is the wattage need when using a power supply**
A: On the placard for the product that I bought, as well as in the product specs, the amperage is listed as 3.5A, with a maximum of 7.5A(presumably when the pump starts). Ohm’s law states that P=VI, so this yields an average of 12V*3.5A = 42W with a worst case of 12V*7.5A=90W.
