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?

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

Yes it has a pressure switch that shuts it off when you shut the flow of water off

What is the power usage for this motor? Amp hours would be best, but pretty much any measure would be helpful.

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

What is the wattage need when using a power supply

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.

流量が説明書に合っている

除草剤散布用にセット準備しています。簡単な測定ですが、ホース先端開放で0.05Mp 5ℓ（約30秒）噴射ノズルをセットして 03Mp 1.3ℓ （約30秒）音はとても静かです。
