Frequently Asked Questions
What is the maximum suction depth for a 1 HP shallow well pump?
Most 1 HP shallow well pumps, like the Red Lion RJS-100-PREM, can lift water from depths up to 25 feet. If your well is deeper, you may need a convertible jet pump or a submersible pump. Always measure the vertical distance from the pump to the water level.
Can I use this pump for a sprinkler system or irrigation?
Yes, the 23 GPM flow rate is sufficient for moderate irrigation and sprinkler systems. However, you must confirm that your pressure tank and piping can handle the demand. For larger setups, a dedicated irrigation pump might be more efficient.
How often should I replace the pressure switch on a shallow well pump?
Pressure switches are durable but can wear out over time. Inspect yours annually for signs of corrosion or sticking. In 2026, many homeowners choose to replace the switch every 5–7 years as preventive maintenance. For more about pressure systems, see our Pressure Systems category.
Does the Red Lion RJS-100-PREM require a separate pressure tank?
Yes, like all jet pumps, it needs a pressure tank to maintain system pressure and reduce cycling. The pump includes a pre-set 30/50 pressure switch, but you must supply a compatible tank. Refer to the manufacturer’s manual for tank sizing recommendations.
