Red Lion Pressure Switch Kit For RJS-PREM Jets
The Red Lion kit is designed specifically for RJS-PREM shallow well jet pump models. It includes a pressure switch, tubing, and fasteners, making it a convenient repair option for compatible systems. This kit also doubles as a repair kit tailored to the Red Lion RJS-PREM line, ensuring a proper fit and seal when replacing worn components. It’s not recommended for other jet pumps due to potential mismatches in connections, but for RJS-PREM users it provides a streamlined, manufacturer-supported solution.
H2O PRO Jet Pump Pressure Fitting Kit
This fitting kit is purpose-built to connect a pressure switch to a jet pump, including two 1/4″ elbows and a small plastic tube. It also serves as a compatible option for pressure regulators and frost-proof yard hydrants. The kit emphasizes an easy, straightforward installation, helping ensure a secure, leak-free connection between the pressure switch and pump without requiring advanced plumbing skills.
Xlajiao 40-60 PSI Pressure Switch
The Xlajiao model offers adjustable 40-60 PSI sensing with a brass construction and ABS housing. Its standard 1/4″ female NPT fittings fit many jet, submersible, and reciprocating pump configurations. The brass body provides durability in exposed pump environments, and the design supports typical residential and light-commercial water systems where reliable on/off cycling is needed to protect pumps from short cycling and water hammer.
Merrill MPS4060 40-60 PSI Switch
The Merrill MPS4060 is a widely used pressure switch for water wells, offering a 40-60 PSI range with adjustable differential. It targets a broad spectrum of electrically driven well pumps, including jet, submersible, and Reciprocating types. The large silver contacts are designed for longer service life, helping reduce maintenance frequency in small farm and rural home irrigation systems. This model emphasizes solid electrical contact durability and reliable cycling.
Sevenjungle 40-60 Psi 2-Pack
The Sevenjungle dual-pack provides two pressure switches featuring a 40-60 PSI range with adjustable differential. It includes a weatherproof, IP54-rated enclosure suitable for outdoor installations, and stainless steel contacts designed for durability in challenging climates. The switches are crafted to handle up to 100,000+ cycles, making them a practical option for farms or homes with outdoor well systems where exposure to dust and moisture is a concern.
Square D 9013 FSG2 Pumptrol
The Square D 9013 FSG2 Pumptrol is a 30/50 PSI pressure switch with IP54 protection and a 1/4″ connection. It is suitable for jet, submersible, and reciprocating pumps, offering dependable performance in residential water systems. While the 30/50 PSI range is slightly lower than some 40/60 PSI models, it remains a solid choice for smaller or older jet pump configurations where precise cut-in/cut-off pressures are not critical for flow stability.
GP Enterprises RP00K0015 30/50 Switch
The GP Enterprises RP00K0015 switch is compatible with a variety of pump models and focuses on a straightforward 30/50 PSI on/off cycle. It supports a range of pump types listed in its compatibility notes and uses standard 1/4″ NPT connectors. This option is suitable for converting older jet pump setups or for upgrading to a reliable, widely available switch with simple wiring instructions. The emphasis is on compatibility with common residential pump configurations.
Merrill MPS3050 30-50 PSI Switch
The Merrill MPS3050 offers a 30-50 PSI pressure setting with adjustable differential, suitable for a broad range of water well pumping applications. The 1/4″ female NPT connection aligns with common jet pump equipment, and the design emphasizes reliable performance with longer life through durable contact materials. This model is a practical choice when a slightly lower pressure range fits the system’s water demand profile or when upgrading from a older 30/50 setup.
Buying Guide: Key Purchase Considerations
When selecting a pressure switch for a jet pump, consider the following factors to ensure compatibility, reliability, and long-term value:
- Pressure range and differential: Common residential targets include 40-60 PSI or 30-50 PSI. Ensure the switch’s cut-in and cut-off pressures match your system’s needs and the pump’s flow requirements.
- Compatibility with pump type: Jet pumps, shallow well systems, submersible pumps, and reciprocating pumps may have different connection standards and mounting needs. Verify NPT size and electrical ratings for your setup.
- Electrical durability: Look for switches with robust contact materials and corrosion resistance, especially in outdoor or humid environments. Higher cycle durability is beneficial for systems with frequent cycling.
- Protection rating: For outdoor installations, IP ratings (like IP54) indicate resistance to dust and moisture, improving reliability in exposed locations.
- Installation ease: Some kits include fittings, tubing, or mounting hardware that streamline setup. Consider whether you need a simple swap-in replacement or a more complex wiring configuration.
- Brand and compatibility notes: Some products are specifically designed for certain models or lines. Using a model not compatible with your pump can lead to improper operation or leaks, so check manual recommendations.
- Maintenance and availability: Choose widely available models with accessible replacement parts and clear wiring diagrams to minimize downtime.
For system designers and homeowners, it is often prudent to match the switch to the pump’s original specifications where possible, or select a model with clear compatibility guidance and straightforward installation steps. Evaluating a mix of kit contents, durability, and warranty terms also helps protect against early wear and unplanned replacements.
