Residential Tank SizingResidential Tank Sizing – How to Calculate, Purchase & Install

Building a new residential water well system is a very detailed process. Although ensuring you have ample water supply to access on your property might seem to be the most important item, finding a qualified company that offers residential tank sizing to help you with this process should be on top of the list. For those that are new to this process or are in need of a replacement water storage tank, there are a few important steps that you should follow that will make this process smooth and seamless.

Noted below are three important steps that will explain the best practices to follow in regards to residential tank sizing.

First – How to Calculate Water Tank Size

Similar in many ways to picking the right sized HVAC system, there is a specific process involved in determining the perfect sized water tank for your residential system. In general, there are three factors that must be factored when calculating water storage tank sizing:

  1. What is the pumps delivery rate in gallons per minute (GPM) or liters per minute (LPM). The delivery rate of the pump will determine the volume that your tank can receive water.
  2. What is the recommended minimum running time of the water well pump? Each residential water well system has a unique pump system that has a recommended minimum running time. Some submersible pumps have shorter running time than above ground pumps and vice-versa. Knowing these numbers from the manufacturer of the pump is required in order to calculate the right sized storage tank.
  3. What are the minimum and maximum cut-in and cut-out system pressure parameter ratings? A water well pump activates by gradually increasing the volume of water from a below ground tank. This is known as the cut-in and cut-off rate.

Most home owners do not have access to this information, which is why it’s important to work with a professional water well construction company who can contact the manufacturer of your water pumps to access these vital numbers. When the numbers are received, a detailed calculation will be completed by the residential tank installation company to provide you with the recommended size.

Second – Where to Purchase the Right Sized Water Tank

Once you have a recommended size of replacement or new water storage tank considered, you’ll need to find a place to purchase the storage tank. There are many direct manufacturers that sell above ground storage tanks for residential applications online. The problem with ordering these systems independently is the cost of shipping and the potential issues with the return of faulty or damaged materials. To reduce the potential for mistakes, it’s always a good idea to work with the same company that completed the water storage tank calculation initially, as they will provide you with options that will fit your needs and budget perfectly.

Third – Proper Water Tank Installation Tips

Once the right tank has been ordered and has arrived, proper installation will ensure that the water tank is safe, secure and free of debris and leaks. There are several filtration systems, hoses and supply lines that run to and from the storage tank. Making sure each line is in good shape, has solid, rust-free connections and is not contaminated is the most important thing to verify before installing any new storage tank.

Working with an experienced and professional water storage tank installation company can significantly reduce mistakes commonly made in regards to residential tank sizing and installation. It will also save you money, time and ensure your system is properly installed, and ready to supply your property with fresh water anytime it’s needed.
