  • Measuring cup
  • Protective gear

Then, let’s clean your water well screen. First, open the priming plug port, which is usually located before the pump inlet. Then add the acid. Remember to wear protective gear such as a face mask and gloves. And the granules need to dissolve slowly and gradually reach the water well screen. Finally, after about 12 hours the acid will clean off the build-up sediment.

What are the Best Materials for A Water Well Screen?

 What are the Best Materials for A Water Well Screen

Water well screen is available in a variety of materials, such as stainless steel, PVC, galvanized carbon steel, carbon steel, etc. However, based on their properties, stainless steel and PVC materials are the suitable choice.

A stainless steel water well screen has high mechanical strength, but corrosion resistance is low and costs more. PVC water well screen enjoys outstanding corrosion resistance and is lightweight, but it is not stronger than stainless steel.

What are the Various Designs of a Water Well Screen?

 What are the Various Designs of a Water Well Screen

These include continuous slot screens, slot pipes, torch cut screens, wire wrap, bridge slots, shutter screen design, etc. Each of them has a unique efficiency level, if you want to buy a suitable one, you can get a recommendation from a water well driller or Filson professional sales.

How to Do When the Flow Rate Doesn’t Increase after Cleaning

 How to Do When the Flow Rate Doesn’t Increase after Cleaning

You can check the well pump, groundwater level, or water filters. What’s more, a pressure booster pump or constant pressure valve can also increase water pressure.
