Just purchased foreclosure, water at some faucets not others?

[Ian Saingarm]

Hi guys, long story short, we got a great deal on a house that has not been lived in for a year or so.  We got the septic up and working, power, and water main at the street (looks like there is an open close knob and two check valves?) and the water main at the house all the way on.  We are on a community well with a water main at the street and a pump house down the street.

The outside spigots all flow acceptably, inside the house both bathroom faucets flow well but one shower drips (even when off) but doesn't flow when turned on.  The kitchen faucet barely flows.

Hot water does not flow on any of the faucets or showers, the hot water heater filled up, turned on, and heated up.  

Is there a way to figure out where  clog might be or any other suggestions/advice before we hire a pro?

Thank you!
