Check valve with suction strainer FERRO K22 1" for water systems

FERRO K22 1" check valve with integrated suction strainer is designed for water systems to provide one-way flow control while protecting pumps and piping from debris. The compact assembly combines a non-return mechanism with a basket-style strainer to prevent solids from entering pump intakes and suction lines. Constructed for domestic and light commercial use, the unit fits 1" connections and is suitable for horizontal or vertical installation where particle protection and backflow prevention are required.

Advantages

The check valve with suction strainer delivers reliable backflow prevention and simultaneous filtration in a single unit, reducing the need for separate inline strainers. Its basket strainer captures particles before they reach the pump impeller, lowering the risk of damage and maintenance frequency. The 1" connection size and compact body simplify installation in tight spaces, while the combination of valve and strainer saves pipeline length and installation time compared with separate components.

Suitable for

• Domestic water supply systems and household pumps
• Garden irrigation and rainwater harvesting pump intakes
• Shallow well and surface water suction lines
• Light commercial water installations requiring particle protection

Key specifications

• Connection size: 1" (one inch)
• Integrated basket-type suction strainer
• Function: one-way flow (non-return) with particle filtration
• Application medium: potable and non-potable water (depending on installation and local regulations)
• Typical installation orientation: horizontal or vertical suction lines
• Suitable for use with centrifugal pumps and other water-handling pumps

How to use

Install the FERRO K22 on the suction side of the pump with the flow direction matching the arrow on the valve body. Ensure all connections are sealed and tightened to the appropriate torque for 1" fittings. Position the strainer basket so it is accessible for inspection and cleaning; periodic removal of accumulated debris will maintain flow performance. Prime the pump and check for leaks initially, then operate the system while verifying that the valve prevents reverse flow when the pump is off.

Usage recommendations

Inspect and clean the suction strainer regularly, especially after initial installation or when drawing from sources with visible suspended solids. If used in systems with high debris load, consider pre-filtration or screens upstream to extend maintenance intervals. Follow pump manufacturer guidelines for suction lift limits and hose lengths to preserve pump performance and avoid cavitation.
