Well screens within the pump area slowly build up with mineral deposits from the water and slow or stop the flow of water. To clear this up, you will need to use muriatic acid to dissolve the deposits.

Things You Will Need

  • Muriatic acid
  • Measuring cup
  1. Go to the well pump and find the priming plug port just before the pump inlet.

  2. Measure out a small amount of muriatic acid and pour it down the plug port. The acid eats away at the buildup that is clogging the well screen. Muriatic acid comes in granules for easy application and fewer chemical fumes. A minimal amount of approximately 1/4 to 1 cup is generally all you need. If this doesn't work, you can always add a little more in a second application.

  3. Wait approximately one hour to allow the chemical to work. In granule form, it is slow to release. Test the water flow to see if it has improved. If not, continued to test it off and on over the next few hours. You should notice better water flow. If not, then apply 1/4 cup more of the muriatic acid granules to the plug port and wait a while longer.
