Also, can you adjust the switch to shut off the tank at 75psi? If so, how? is it done through the code?

Aloha!!!
There are a few things that could be wrong. Although the pump works in either polarity, it is more efficient and will run cooler when running in the correct direction. It is possible that the wiring feeding the compressor has a loose crimp or that you have a defective breaker which will supply less current to the compressor. The compressor has a pressure relief valve that is designed to pop open at 125-130 PSI that may be damaged and leaking. It is the brass fitting connected to the head of the compressor. Finally, screw fittings should be assembled with Teflon tape (available at any hardware store) to help seal the connection. 90% of the problems with pneumatics are leaks. If you system is already assembled with valves in place, clamp the tubing as it exits the storage tanks and see if the compressor will reach full 120 PSI. Valves sometimes leak especially when installed backwards.
Aloha!

Re: Our pump has problems!

We had this problem earlier too - it turned out the pressure relief valve in the compressor was damaged. We replaced it and our problem went away.
