There are a few components that are vital to consider if your home draws its water from a well, and your pressure tank is at or near the top of any such list. Ensuring you have the right pressure tank size to meet your home’s water demand is one of the most important considerations when choosing your tank.
At Mike Zimmerman Well Service LLC, we’re proud to offer a variety of water well pressure tank services and related solutions, including help with sourcing the ideal pressure tank size and format for your needs. Here is a general pressure tank sizing guide that includes all the important variables to consider when matching your well’s pressure tank with your home’s water demand.
Identifying Pump GPM
When it comes to the size and output of a water well pressure tank, one of the most important figures to be aware of is the system pump’s gallons per minute (GPM) rating. This refers to how many gallons of water the pump can supply in one minute. For example, a 10 GPM-rated pump can provide 10 gallons of water in a minute.
As you may have guessed, bigger pumps naturally require bigger pressure tanks to match their output. This is because the larger the pump, the more water it can supply at a given time, and therefore, the more water will need to be stored in the tank.
Pump size for a given home tends to correspond with the number of bathrooms and occupants in the household. A larger home with more bathrooms and people will require a bigger pump size to meet their demand for water.
Considering Drawdown
Another important factor when it comes to choosing a water well pressure tank is considering the drawdown. Drawdown refers to the amount of water that can be stored in the tank before the pump turns on again to refill it, or effectively, the amount of water delivered in each cycle.
The pressure tank you choose for your system must provide enough drawdown to reduce pump cycling, as frequent pump cycling can lead to reduced lifespan of the pump. A larger tank will have a larger drawdown and therefore reduce the frequency of pump cycling, making it more efficient and cost-effective in the long run. However, keep in mind that a larger tank also means a higher initial cost and requires more space for installation.
Key Factors in Household Demand
Once you’ve considered pump GPM and pressure tank drawdown qualities, it’s time to identify the chief factors in your home’s water demand to identify the ideal tank to use. Some major elements:
- Number of bathrooms and fixtures: One of the most obvious but important factors in determining water demand is the number of bathrooms and fixtures in your home. More bathrooms typically mean more daily usage and, therefore, a higher demand for water.
- Irrigation needs: Does your household or backyard require irrigation? If so, this will greatly impact your water usage and should be taken into consideration when selecting a pump and pressure tank. If any livestock live on your property, your irrigation and watering needs may be even higher.
- Number of occupants: Of course, the number of people living in your home will have a major influence on water demand. The more individuals use water on a daily basis, the higher the demand will be.
- Water usage habits: It’s also important to consider the habits and routines of those living in your household. Do you have multiple individuals taking long showers or running loads of laundry each day? This will increase water demand and affect which pressure tank is best suited for your home.
- Appliances and fixtures: Lastly, take into account any appliances or fixtures that require water in your home. For example, a dishwasher or washing machine will also contribute to your overall water usage and demand.
Importance of Not Under-Sizing a Water Well Pressure Tank
A water well pressure tank that’s too small will lead to rapid cycling of the system’s pump, forcing it to turn on and off frequently in a standard system. This will not only increase your energy costs but also put unnecessary wear and tear on the pump, reducing its lifespan. Additionally, frequent cycling can cause fluctuations in water pressure, leading to inconsistent water flow and potential damage to your home’s plumbing. However, rapid cycling can be addressed or minimized by upgrading to a constant pressure system, which helps maintain steady water pressure and reduces pump cycling..
This is why it’s important not to undersize your water well pressure tank. By choosing a properly sized tank, you can ensure efficient operation of your water well system and avoid unnecessary expenses in the long run.
