Jabsco 1 Inch In-Line Non-Return Check Valve - Part 29295-1000

The Jabsco 29295-1000 is a 1 inch in-line non-return (check) valve built for marine suction hose lines. It is constructed from corrosion resistant plastic with a nitrile rubber valve, making it suited to the wet, salt-exposed environment inside a boat's bilge and plumbing runs. The valve is designed to fit simply into a 1 inch (25mm) bore suction hose, most commonly on the inlet side of a pump.

Its primary function is to aid pump priming and to stop water from flowing backward through the suction line into the bilge once the pump shuts off. This keeps the pump primed for the next cycle and helps prevent unwanted water migration back through the system. The valve has two ports and an adjustable port configuration, so the hose connections can be angled for a convenient, kink-free routing during installation. The inlet is sized for a 1 inch bore hose while the outlet uses an NPT threaded connection.

In its in-line configuration the valve measures 108 mm long by 55 mm wide by 50 mm high and weighs approximately 0.2 pounds, making it compact enough to fit into tight bilge or plumbing compartments without adding significant weight to the system.
