When it comes to discussing water pressure for a well, the general perception is that the more pressure, the better it is. However, most private well owners keep water pressure between 40-60 PSI. It works optimally for a medium to large size home.
In this article, we will discuss what good water pressure for a well is. In other words, what is an optimum water pressure which can help you do all your work efficiently without facing any pressure problem and wasting a lot of water?
First of all, you need to assess what pressure of water you need? By considering the following factors, you can reach to a conclusion.
Factors that Dominate Pressure Settings
The distance of your house from the well – If your house is not located in close proximity of the water well, you will need high water pressure setting so water can reach your place. For homes located very near to wells, lower pressure can work as well.
The number of maximum faucets running simultaneously – The number of faucets running simultaneously matter a lot when it comes to deciding the pressure of water. If you have a large family, you would need high pressure to satisfy the needs of every family member during the peak time.
Numbers of stories in your house – Multistory homes need high pressure. When your water system has to pump water against gravity, it needs more pressure to do it effectively. High rise buildings use booster pumps to increase water pressure.
The number of appliances that need high pressure – The number of appliances in your home also impact the required pressure. Moreover, water treatment systems also require a constant pressure to function effectively. Low pressure can result in poor functioning of these machines.
The capacity of your pressure tank and pump – Another factor that comes into play while deciding what is a good pressure for your well is the capacity of your pressure tank and pump. Some pumps cannot handle high-pressure settings, and hence they would stop working after a short time. If you are installing a new pump or drilling a new well, make sure you install a high-quality, durable, and versatile pump that can handle different pressure settings.
Different Pressure Settings
Most of the residential wells work with three different pressure settings. Typical pressure settings on a standard pressure system are 20/40, 30/50, or 40/60 PSI, 20/40 being the lowest and 40/60 being the highest. You can easily switch between the pressure settings by adjusting the pressure switch.
What’s a Good Pressure?
Different factors come into play when you are deciding the best pressure for your well water. Let’s look at some different scenarios and what pressure is good for them.
- You have a small home with a small family of 2-3 people, and your well is located close to residential unit and you only have a couple of water appliances. You can keep the pressure settings at 20/40 PSI or 30/50 PSI. You have a small home with 2-3 people, but the well is located far away, high pressure would be best for you. Similarly, if you have more individuals living in your home, set the pressure to 40/60 PSI.
- You have a large home with 2-3 people living inside it, and it is located near to the well, low pressure would do the trick. You have a large home with 6-8 or more inhabitants; don’t think about keeping the pressure below 40/60 PSI. You may need a pressure booster or a constant pressure system for large homes located far away from the well.
- Check your well water pressure tank and ensure that the air pressure is 2-3 PSI below the low pressure on pressure switch. For example, if pressure switch is set to 40/60 PSI, the pressure tank must have 38 PSI air pressure.
Water wells and Irrigation
Some people living in the countryside also use wells to irrigate their fields. The relationship between a water well and irrigation is a complex one, and it requires a lot of calculations to determine the pressure you need from your well. Anything above 20 gallons per minute would be good for small agricultural field. For commercial purposes, you would need powerful devices.
Final Word: Be intelligent and adjust the right pressure
