The Red Lion Replacement Overhaul Kit (model 305584008) is a repair kit designed exclusively for the Red Lion RJS-100-PREM 1 HP shallow well jet pump. It is intended for homeowners and professionals who need to restore an aging or failing pump without the expense of full replacement. The kit contains the most commonly replaced internal components, including the impeller, mechanical seal, nozzle, venturi, O-ring, and volute.
One standout feature is that all parts are genuine OEM components manufactured by Red Lion, a Franklin Electric brand. This ensures a precise fit and reliable performance, which aftermarket parts may not guarantee. Customers report that the kit saved them from spending hundreds of dollars on a new pump, and the high customer rating of 4.6 out of 5 stars reflects its effectiveness in restoring pump function.
Build quality is solid: the mechanical seal uses carbon and ceramic materials, while the impeller and other parts are made from glass-filled thermoplastic and stainless steel. These materials resist wear and corrosion, contributing to a long service life. The kit is lightweight and compact, making it easy to handle during repair.
However, there are a few drawbacks. The kit does not include step-by-step installation instructions; you need the original pump manual for proper assembly. Additionally, some users noted an extra O-ring and the lack of torque specifications, requiring careful disassembly reference. The kit is also model specific, so it cannot be used on other jet pumps.
Overall, the Red Lion RJS-100-PREM Overhaul Kit is a highly recommended investment for anyone looking to revive their shallow well jet pump. It combines genuine quality with cost savings, and with proper installation it can restore your pump to like-new performance.
