The Red Lion RJS-100-PREM is a robust shallow well jet pump designed for homeowners needing effective water delivery. It boasts a powerful 1 HP motor, drawing up to 23 gallons per minute, making it suitable for various household uses. Its rugged cast iron construction ensures durability, which is a significant plus for long-term performance. The pump operates on either 115 or 230 volts, offering flexibility based on your available power supply. Additionally, it comes with a factory pre-set 30/50 pressure switch and a pressure gauge, allowing for easy monitoring and adjustment of water pressure within your system.

One of the strengths of this pump is its ability to produce a maximum pressure of 50 PSI and a maximum head of 150 feet, making it capable of handling a range of applications, from irrigation to supplying water to homes. However, potential users should note that the pump's size and weight may require additional support during installation, as it is a bit bulky due to its cast iron build.

While the heavy-duty motor is effective, it may consume a considerable amount of electricity, particularly if used at the higher voltage setting. Users should also be aware that the pump may require regular maintenance to ensure optimal performance, especially in areas with hard water, which can affect the internals over time.

Buying Guide for the Best Well Pump Pressure Switch

Choosing the right well pump pressure switch is crucial for ensuring that your water system operates efficiently and reliably. A pressure switch is a device that controls the operation of your well pump by turning it on and off based on the water pressure in your system. To make an informed decision, you need to understand the key specifications and how they relate to your specific needs. Here are the main factors to consider when selecting a well pump pressure switch.
Pressure RangeThe pressure range of a well pump pressure switch indicates the minimum and maximum pressure levels at which the switch will activate and deactivate the pump. This is important because it determines the water pressure in your system. Common pressure ranges include 20-40 psi, 30-50 psi, and 40-60 psi. If you have a small household with low water demand, a lower pressure range like 20-40 psi might be sufficient. For larger households or higher water demand, a higher range like 40-60 psi would be more appropriate. Choose a pressure range that matches your water usage needs to ensure consistent water pressure.
Cut-In and Cut-Out PressureCut-in pressure is the point at which the pressure switch turns the pump on, while cut-out pressure is the point at which it turns the pump off. These settings are crucial for maintaining the desired water pressure in your system. For example, a switch with a cut-in pressure of 30 psi and a cut-out pressure of 50 psi will start the pump when the pressure drops to 30 psi and stop it when the pressure reaches 50 psi. Adjust these settings based on your water pressure requirements and the capacity of your well pump to ensure optimal performance.
Differential PressureDifferential pressure is the difference between the cut-in and cut-out pressures. This spec is important because it affects the frequency of your pump's operation. A smaller differential means the pump will cycle more frequently, which can lead to wear and tear, while a larger differential means the pump will run less often, potentially extending its lifespan. For most residential applications, a differential of 20 psi is common. Consider your pump's durability and your water usage patterns when selecting the appropriate differential pressure.
Switch TypeThere are two main types of well pump pressure switches: standard and low-pressure cut-off. Standard switches are suitable for most applications, while low-pressure cut-off switches are designed to protect the pump from running dry by shutting it off if the pressure drops too low. If your well has a tendency to run dry or if you have a shallow well, a low-pressure cut-off switch can provide added protection for your pump. Choose the switch type that best matches your well conditions and pump protection needs.
Electrical RatingsThe electrical ratings of a pressure switch indicate the voltage and current it can handle. This is important to ensure compatibility with your well pump and electrical system. Common ratings include 115V and 230V, with varying current capacities. Check your well pump's specifications and your electrical system's requirements to select a pressure switch with the appropriate electrical ratings. This will ensure safe and reliable operation of your well pump.
