Whale In-Line Check Valve LV1215

Precision Non-Return Valve for 25.4mm & 38.1mm Hose

The Whale LV1215 is a professional-grade in-line non-return (check) valve essential for any marine plumbing system. Designed with a unique stepped-barb configuration, it allows for a direct fit to both 25mm (1") and 38mm (1.5") internal diameter hoses. This valve is critical for preventing the backflow of water into the bilge or grey water tanks, ensuring your pumps remain primed and efficient.

RELIABILITY: Built from corrosion-resistant, high-impact materials to withstand the harsh marine environment and prevent pump cycling.

Questions & Answers

Is this a genuine Whale part?

Yes, this is a genuine Whale LV1215 component, known for its high standard of marine engineering and durability.

How do I install it for different hose sizes?

The valve features stepped barbs. For 25mm (1") hose, use the first step. For 38mm (1.5") hose, the hose slides over the larger secondary step. Use marine-grade stainless steel hose clamps for a secure seal.

Can this be used with fuel or oil?

No, the Whale LV1215 is designed specifically for water applications (freshwater, saltwater, or grey water). It is not recommended for use with fuels or chemicals.

Note: At 4boats.co.uk, we recommend verifying your hose diameter before purchase to ensure a perfect fit. Always ensure the flow arrow on the valve body points in the direction of discharge.
