Once youve found it, look for a knob or screw that you can turn to adjust the pressure setting. The pressure gauge measures the current pressure in the system, while the pressure switch controls the cut-in and cut-out pressures. But let's don't mix pressure and flow; if the actual flow rate at fixtures is weak then it could be that there are clogs in the piping system or a valve partly closed, or the well flow rate could be limited. The larger nut shifts the whole cut-in/cut-out pressure range up or down, while the smaller nut changes the width of that range - the differential between cut in and cut out. Do not use chemicals to clean the contacts. Then, observe the length. Luckily, you may be able to fix the problem yourself with a little bit of troubleshooting. This ensures your own safety. Then turn it back on to reach a cut off pressure I suspect the problem is in your well and the well flow rate and it would just be a waste of ex's time and energy to change switch.
