Water Well Casings Repair: What You Need to Know
A well casing is an important part of all wells. It helps hold up the structure of the well. Damage to well casings requires immediate attention and repairs from professionals. In the blog, we will discuss the workings and repairs of well casings. We hope to clear all your doubts and questions regarding well casings. Let’s get started.
What is the purpose of water well casings?
The water well casing forms the structure of the well and acts as a pathway for the water to flow to the top from the source. A water well casing is designed to prevent dirt, contamination, and sediments from entering the water supplied to the top.
The dug-up raw wall of the well has a high chance of collapsing since it is made up of loose rock and gravel. This is why a well casing is placed inside a well.
Residential water well casings measure between 4 and 6 inches, and commercial water well casings are wider due to greater requirements.
These water well casings have a cap that is made up of plastic or aluminum, which prevents bugs, dirt, small animals, and leaves from falling into the well. This cap is not entirely sealed off. It has a vent that helps manage the water pressure when you pump water.
These well casings are mostly made up of materials like plastic and steel. Steel can be either carbon or stainless.
In the earlier times, people who owned wells often chose steel casings. But nowadays, PVC casings are becoming more popular. This is all because PVC has gotten stronger, more durable, and better at resisting corrosion.
Which material should you choose for water well casings?
Suppose you are looking for a water well casing and are confused about which material to choose. Here are some factors that will help you find the suitable material. First, you should consider the rules and regulations in your area. Next, look at the tools and equipment used to build the well. Lastly, don’t forget about the cost, which is important too.
Your professional water well builder might also consider other factors, like your area’s water chemistry and geology. Also, it might be corrosive if your well water is too acidic, has a pH below 6.5, and lacks alkalinity.
In situations like this, where the water is too acidic, your water well contractor will use PVC pipes because they are resistant to PH corrosion and will not be affected by galvanic corrosion.
Also, if the water from the well has many dissolved substances in it, like minerals, it might damage steel pipes because of galvanic current.
When the professional well casing installation contractor is working, they will make sure that the material is not bent to avoid damage to the materials. A damaged casing will cause a lot of harm in the future. For example, it might mess up the well’s structure and make it hard to install the pumping equipment. It will also become difficult to conduct repairs and maintenance by removing the pumping equipment.
Some Common Signs of Leaks in Your Water Well Casing
Most homeowners know that it is important to maintain their well casings. But sometimes, it might be difficult to notice a well casing leak, particularly below the surface. Here are some signs that will indicate that you will need a water well casing repair immediately.
- Water flow slows down over time.
- Your water may have sand, dirt, or other stuff in it.
- Filters for your water system need to be changed often.
- You find out there’s a new issue with the water quality due to contamination.
It is a good idea to contact a water well repair contractor every year to have your well inspected and taken care of. During this check-up, the contractor will look for any leaks or problems with the casing. If they find any issues, they’ll fix them or replace the damaged casing to ensure your well keeps working smoothly.
The Process of a well Casing Repair
If you notice any signs of a leak, contact a local well casing repair contractor. Once they arrive, they will put down a camera into your well. This will help them thoroughly inspect what problems have brewed up down there.
Once they understand the nature of the problem, they will look for the best and most affordable way to fix it and then give you a quote. All the decisions will be based on the number of leaks.
Smaller leaks are easier to fix and can be easily repaired using a well liner or a repair sleeve. A repair sleeve is small and fits snugly inside the casing without causing any issues.
Your contractor will put the sleeve over the leak and seal it to make sure it stays put.
But if the leak is big or if the well casing is corroded, fixing it isn’t as easy. In these cases, using a sleeve to cover the leak might not be possible.
