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!

Super compact, great performance

This little pump does a great job, particularly for how small it is. It was the perfect choice for my small truck/camper system. The plastic construction is robust and feels to be well manufactured. Installation is very simple: attach 3/8" ID hose to barb connectors with hose clamps and connect the positive and negative wires to your 12V source via a switch or relay. Water pressure was very good when running directly at full flow, but when running with partially open valve (restricted flow), the pump's pressure switch causes rapid on/off cycles. I chose to couple the pump with a 0.75L accumulator to eliminate this chatter and reduce electrical/mechanical wear. Very happy with the overall performance of this water pump.
