Inline check valve

This non-return valve, part number LV1215, belongs to Whale’s Bilge Accessories range. It is specifically designed for manual bilge pumping and dewatering systems. As an inline accessory, it is intended to be installed in an existing pipeline. It is recommended to verify the exact part number and compatibility with the components already installed on your vessel before ordering or installation.

The Whale LV1215 inline check valve must be installed directly in the discharge line of the bilge pumping system. Its positioning must be strategic to effectively prevent water from flowing back into the bilge after manual pumping. It integrates into the piping circuit to ensure unidirectional flow.

The Whale LV1215 inline check valve is an accessory designed for manual bilge pump and drainage systems. Its primary function is to prevent already pumped water from flowing back into the bilw, ensuring efficient and long-lasting water evacuation.

A check valve is a device that allows fluid (in this case, water) to flow in only one direction. Its main purpose is to prevent water pumped out of the bilge from flowing back into the boat once the pump stops, ensuring the bilge remains dry.

The exact model of this check valve is the Whale LV1215. It is also known by the supplier reference WHA-LV1215 and its barcode is 766478121509.

The Whale LV1215 check valve is typically made from durable plastic materials such as polypropylene, designed to withstand marine environments and corrosion.

Yes, the Whale LV1215 check valve is specifically designed for marine use and is made from materials resistant to seawater corrosion.

Yes, this check valve is specifically designed for manual bilge pumping systems and bilge drainage, as stated in its description.

Yes, although the description mentions manual pumping, a check valve is a passive component that can be integrated into an electric pumping system to prevent water backflow. Its function remains the same regardless of the type of pump (manual or electric).

A check valve is typically installed on the discharge line of a bilge pump. It can be placed below or above the waterline, but it is critical that it is properly connected and watertight to prevent any water ingress if the outlet is submerged.

Whale check valves such as the LV1215 are typically sealed units and are not designed to be repaired with spare parts. In case of failure, the entire unit must be replaced.

The valve is installed inline on the discharge hose of your bilge pump. Simply cut the hose at the desired location, insert the valve at both ends of the hose, and secure it firmly with suitable hose clamps to ensure a perfect seal.

The non-return valve must be installed in the direction of water flow. It usually has a molded arrow on its body indicating the direction in which water must flow (from the boat toward the outside). Ensure this arrow points toward the boat's outlet.

The non-return valve must be installed on the discharge pipe, between the bilge pump and the hull outlet. It is often recommended to place it as close as possible to the hull outlet to minimize the volume of water that could potentially backflow.

For installation, you will generally need a pipe cutter or a knife to cut the existing hose, and a screwdriver or socket wrench to tighten the hose clamps on the valve fittings.

Yes, it is essential to use high-quality stainless steel hose clamps at both ends of the valve to ensure a tight and secure connection on the hose, preventing leaks and disengagement under pressure.

Although primarily designed for bilge drainage, a non-return valve of this type can be used in any application requiring prevention of backflow in a line, provided pressure specifications and fluid compatibility are met. For example, it could be used in certain fresh water circuits or grey water discharge systems aboard.

The Whale LV1215 inline non-return valve is designed to prevent backflow of water or other fluids in a piping system. Its primary function is to ensure that the pumped liquid does not return to its source once the pump is stopped. It is particularly useful for manual pumping and bilge drainage, ensuring efficient evacuation without unwanted water backflow.

To install the Whale LV1215 inline check valve, it is essential to respect the fluid flow direction. This direction is usually indicated by an arrow on the valve body. It must be installed directly inline in the pipe, between the pump and the discharge point. Ensure all connections are watertight and secure to prevent leaks and ensure efficient operation.

The Whale LV1215 inline check valve is specifically designed for use in manual bilge pumping systems and for hull bilge drainage on boats. It is compatible with installations where preventing water backflow after pumping is required. For optimal compatibility, ensure the valve is matched to the diameter of your existing piping.
