which side is the inlet ?

There is an arrow pointing from one end to the other. Inlet is the end the arrow starts from. Direction of flow is parallel to the arrow.

can the cut off pressure be regulated/adjusted to about 15psi?

This pump is built with 35psi switch and can not adjusted to 15psi. Thank you!

Im looking to make a water misting system off the side of my rv. Would this pump be good to run for several hours continuously?

Yes, it will run continuously for several hours. I've run it as a transfer pump when needed, and had it running for an entire day. Works great.

Is it a wash down pump?

This pump can be used as a wash down pump. Thank you!
