When you have a well water system, there’s one piece of equipment you rely on constantly: the water well tank. My clients soon find that these tanks are at the center of a home’s water supply system. They don’t just hold water; they also store it under pressure to make sure you have steady, reliable water flow anytime you need it. Without them, every time you turned on the tap, your pump would have to turn on, and that would wear out your pump in no time.
It’s important to me that you know enough about water well tanks to make good decisions about your system. In this post, we’ll cover:
- What is a Water Well Tank?
- Types of Water Well Tanks
- The Importance of Water Well Tanks
- Factors to Consider When Choosing a Water Well Tank
- Installation and Maintenance of Water Well Tanks
Let’s dive in, so you can learn more about why a water well tank is crucial to your home’s water system, the options available, and how to keep yours in great shape.
What is a Water Well Tank?
A water well tank holds pressurized water from your well, so you can access it as needed. It’s like having a reservoir of water ready, which is especially important if you have a large family that uses a lot of water or many different appliances using water at the same time.
Here’s how it works: Your tank holds pressurized water pumped from the well, and when you open a tap, the tank releases this water to the faucet that you have open. When the tank’s water level drops to a certain point, it signals the well pump to refill it, which means the pump doesn’t have to run every time you turn on the water. This setup keeps your water flowing smoothly and helps preserve the well pump's life.
Types of Water Well Tanks
Water well tanks come in a few different types, each with its own advantages. Here’s a quick look at the main options, so you can choose the one that best meets your needs:
Steel Water Tanks
Steel tanks are one of the most durable choices on the market. Their strong outer shell can handle temperature fluctuations and physical impacts, making them sturdy and reliable. They also have capacities that range from 780 to over a million gallons of water, so they’re useful if you have a commercial property to provide water for. Inside, they typically have a rubber diaphragm to separate air and water, which helps maintain a steady pressure. Their main advantages are cavitation resistance, durability, and corrosion resistance.
Fiberglass Tanks
Fiberglass tanks are a popular choice today because they don’t rust, which makes them easy to maintain. They’re lightweight, corrosion-resistant, and often have a longer lifespan than steel tanks, though they tend to cost a bit more upfront. These tanks come in various styles, including underground, vertical, horizontal, and above-ground options. Fiberglass can be a great choice if you’re looking for a “set it and forget it” kind of tank that doesn’t need much upkeep. The main perks are ease of installation, rust resistance, and simple maintenance.
Bladder Water Tanks
Bladder tanks use an internal rubber bladder to completely separate air and water. This design prevents waterlogging (a common problem when air and water mix in the tank) and keeps the tank’s pressure steady without needing regular air refills. Bladder tanks are also typically smaller than the other options, making them a practical option if you’re limited in space. Their top advantages are efficient water pressure maintenance and fewer disruptions in the water supply.
The Importance of Water Well Tanks
Water well tanks are more than just water storage units—they’re what keep your water system efficient and reliable. Here’s why they’re so important:
- Water Pressure Regulation: With a well tank, you’ll have steady water pressure whether you’re running one faucet or multiple taps at once. The tank releases pressurized water when needed, so you don’t end up with weak water flow, even if your family is using several water sources at the same time.
- Storage Capacity: Having a well tank with the right capacity makes sure that you can handle peak water usage without your pressure dropping. For instance, when everyone’s showering in the morning, or you’re running the dishwasher while filling the sink, a well-sized tank means you won’t be left with a trickle of water.
- System Efficiency: The tank makes your whole water system more efficient by reducing the frequency of the pump turning on. Every time the pump cycles on and off, it uses energy and undergoes wear and tear, which adds up over time. A well tank can reduce these cycles, extending the life of your pump and saving you on energy costs.
Factors to Consider When Choosing a Water Well Tank
Choosing the right water well tank is essential, but it doesn’t have to be overwhelming. A good well specialist will help you choose the right water well tank, but here are the key things to keep in mind:
- Size and Capacity: Size matters when selecting a tank. The right tank size depends on your household’s water usage and the number of people in your home. A family with heavy water needs will benefit from a larger tank to avoid constant cycling, which can keep your water pressure steady and your pump in good condition.
- Material Selection: Different tank materials have different strengths. Steel tanks are highly durable, though they’re prone to rust over time, whereas fiberglass is corrosion-resistant but pricier. Bladder tanks require less maintenance but might not last as long if the bladder fails. Your choice will depend on your budget, how much upkeep you’re willing to handle, and your tank’s exposure to environmental elements.
- Pressure Rating: Every well tank has a pressure rating, which is the maximum pressure it can handle. It’s important to match this with your home’s water system. If you choose a tank with a lower rating than you need, your water pressure may struggle to keep up, especially during high-demand times. Selecting a higher-rated tank, however, can improve water flow and reduce strain on your system.
Installation and Maintenance of Water Well Tanks
Installing a well tank properly and keeping it maintained can make a big difference in its performance and lifespan. Here’s what you should know:
Installation Tips
While installing a well tank yourself is possible, it’s often worth hiring a professional. A pro can ensure the tank is properly sized, securely installed, and connected to the well pump. If you’re up for DIY, be sure to follow all installation instructions and double-check that the tank’s pressure settings are correct. The Pinnacle List has tips for installing a well water storage tank if you’re up for the challenge.
Regular Maintenance
Regular maintenance helps your tank meet your water needs and avoid costly repairs. Check the tank’s air pressure every six months to prevent waterlogging, inspect it for leaks, and occasionally clean out the inside if recommended for your particular type and model. This keeps your water flowing smoothly and helps prevent minor issues from turning into major ones.
Signs of Problems
If you start noticing inconsistent water pressure, strange noises from the tank, or your pump cycling too frequently, it’s time to look into it. These could be signs that your tank needs repair or replacement, and catching these issues early can save you from bigger headaches down the line.
Conclusion
Water well tanks are the backbone of well water systems, keeping water flowing smoothly, maintaining pressure, and protecting your well pump. Choosing the right tank, maintaining it, and being able to identify when something’s wrong can make a big difference in your system’s functionality and longevity. Whether you’re new to well water or looking to optimize your system, the right tank will keep your home’s water reliable for years to come.
