How do you fix low well water pressure?

The present pressure pump is 15 years old. We also have sulfur in our water.

Turn up the pressure switch setting (turn it clockwise)

From your question, it is unclear where your problem lies. If you have low pressure at the faucets in your house, the problem could be with a buildup of sulphur compounds in the piping. If you mean that the pressure guage on the pressure tank is too low, you can adjust the pressure switch (located near the pump or near the pressure tank) so that the pump stays on longer — say until the pressure in the tank reaches 60 psi.
There is usually instructions inside the cap of the pressure switch showing which nut to tighten to increase the cut-out pressure. You should probably turn off the power the to pump before removing the cap though since the 220 volt power is very close to the nut you’ll be working on.
If, however, the pressure reaches 60 psi but drops very quickly as soon as a faucet is turned on, this indicates that the bladder in the pressure tank has ruptured and you should really replace the tank. You can effect a temporary fix by turning off the pump, open a faucet until no water flows, then use an air compressor on the snifter valve located on the top of the tank to pre-pressurize the tank to about 40 psi. This will "solve" your problem temporarily, but if the tank bladder is ruptured, the air will soon be absorbed by the water and you’ll be back to square one.

you can’t do any thing about the sulfur. but most pumps be submersible or not there is an adjustable screw to increase the water pressure,turn clockwise. 65
