Simple 3 Steps Guide to Clean a Well Screen

Last updated on June 13th, 2021 at 08:44 am

A well screen is used to stop suspended particles from entering your well. It is placed below the well casing in the well. Over time, a well screen can get clogged due to sediment buildup and deposit of bacteria. Iron bacteria are present in water and form slime on the well screen, which inhibits water flow. The clogging of the well screen causes the recovery rate to decrease and reduces the flow rate. You get slow water while bathing, and all the appliances like a washing machine and dishwashers work slowly due to a low water pressure. Hence, it is crucial to clean the well screen periodically.

In this article, we are going to discuss how to clean a well screen.

How to Clean a Well Screen?

Before you make a plan to clean the well screen, check the state laws. Some states don’t allow well owners to carry out the maintenance tasks. If this is the case, hire a state-licensed well contractor to do it for you.

Things you will need

  • Granular Acid (Muriatic, Phosphoric or Sulfamic)
  • Measuring Cup
  • Protective Gear

Step 1: Opening the Priming Plug Port

First of all, locate the priming plug port of the well. It is usually located before the pump inlet. If you can’t find it, refer to the well completion report. All the ports and other details are mentioned in the blueprints of the well.

Step 2: Adding the Acid

Wear protective gear such as a face mask, safety goggles, and gloves. Measure half or a full cup of the acid and pour it down the plug opening. The granules will dissolve slowly and gradually reach the well screen where the deposits are formed. Granules help in slow releasing and are safe to work with it as compared to liquid acids.

Step 3: Wait for the Acids to Work

The acid will not work instantly. It may take up to 12 hours for the sediment and bacteria deposit to come off. Once the screen is unclogged, you will notice a visible difference in the flow rate and refilling rate. If there is no increase in the flow rate, there may be some other problem with your well.

FAQ

Which is the best protective equipment for cleaning the well screen?

Base camp’s face maskis best for cleaning well screens. DeWalt’s safety goggles are recommended for well cleaning and working with other tools. I prefer using these gloves while handling acids.

I lost my well completion report? Where can I get it?

If you lost your well completion report, you can get a copy from your well contractor. Records about well drilling are also maintained by the respective well water departments of your state. You can also find a copy of the well-completion report online.

What are the best materials for a well screen?

Well screens are made from a variety of materials. You can choose from crude-hand contrivances to highly efficient and long-life models made on a machine. The common materials used for making well screens include stainless steel and PVC.

What are the different designs of a well screen?

You can go for a continuous slot screen, torch cut screens, milled slots, wire wraps, bridge slot, and shutter screen design. Each design has a different efficiency level and is picked according to the dynamics of your well. It is best to go with the recommendation of your well driller.

What to do if the flow rate doesn’t increase after cleaning the well screen?

Suppose you don’t notice a visible difference in the flow rate after cleaning the well screen. In that case, I suggest you go towards other methods like checking the well pump, groundwater water level, check water filters and softeners, install a constant pressure valve or get a pressure booster pump. If nothing works, consult your well driller.

Final Words

It is better to try inexpensive remedies before going for costly repairs and well rehabilitation programs. Make sure you follow all the safety precautions and local laws while dealing with private wells.
