Underhill Gulp Pro Siphon Suction Water Pump 22 in - High Capacity

Our review of the Underhill Gulp Pro Siphon Suction Water Pump finds it best suited for grounds crews, landscapers, plumbers and anyone who needs a rugged, portable tool for water removal. The single biggest reason to buy is its combination of a high per-stroke capacity and a design built for dirty water: the pump delivers large volume per stroke while the patented MudGuard system keeps sediment away from moving parts, making it a reliable choice for repeated field use.

Key Features

• Virtually unbreakable build: A polycarbonate body resists crushing and cracking so the pump survives rough handling in trucks and job sites.
• Patented MudGuard system: Keeps sediment and debris out of the working parts to maintain smoother, more reliable operation in dirty water.
• High capacity per stroke: The clear pump chamber and design deliver roughly a 19 oz capacity per stroke for faster water removal.
• Fully removable parts: Every component disassembles for fast rinsing and maintenance to reduce clogs and downtime.
• Serviceable long life: Replacement parts are available so the pump can be repaired rather than discarded after internal wear.
• Compact and portable: Lightweight construction and a padded ergonomic handle make it easy to carry and stow between jobs.

Who It's For

This pump is aimed at professionals and serious DIYers who need to remove water from sprinkler boxes, valve boxes, fountains, pipe repairs, boats, toilets, spas and similar places where dirty water and grit are present. The combination of the MudGuard and removable internals makes it particularly suited to grounds crews who must repeatedly pump out sediment-laden chambers.

It is less suited to those who expect indefinite indestructibility or who need a completely maintenance-free, throwaway item. Customers reporting internal breakage suggest buyers who demand heavy-impact resistance or the lowest possible upfront price should consider alternatives or budget accordingly for replacement parts.
