Strainer Basket Ferro K21 for 3/4" Connections – Ferro K21

Ferro K21 is a strainer basket designed for 3/4" plumbing connections. It collects debris and prevents particles from entering fittings, valves and appliances, helping to protect plumbing components and maintain water flow. The product is intended for inline installation in supply lines where coarse filtration and protection of downstream devices are required, suitable for residential and light commercial plumbing systems.

Advantages

The Ferro K21 strainer basket offers a straightforward mechanical barrier against sand, scale and other solid particles without changing water chemistry. Its compact design fits standard 3/4" connection points and allows maintenance by removing and cleaning the basket. The device reduces the frequency of repairs and clog-related faults in valves and appliances by intercepting debris upstream.

Suitable for

• Protection of valves, taps and fittings in household plumbing
• Pre-filtration ahead of small water heaters or flow regulators
• Light commercial installations with moderate particulate load
• Inline installation on supply lines with 3/4" threaded connections

When it may not be suitable

The Ferro K21 is not intended as a fine filter for microorganisms, dissolved solids or very fine sediment; it provides coarse mechanical filtration only. It may be unsuitable where certified microbiological filtration or water softening is required, or in systems with unusually high flow demands that exceed the product's intended hydraulic capacity.

Key specifications

• Connection size: 3/4" threaded inline fitting
• Function: removable strainer basket for particle capture
• Application: residential and light commercial water supply lines
• Installation orientation: inline, accessible for maintenance

How to use

Install the Ferro K21 in a 3/4" supply line at a location that allows easy access for periodic cleaning. Shut off the water supply before removing the housing or basket. Unscrew the unit or open the access port according to the system layout, extract the basket, rinse away accumulated debris and reinstall ensuring a proper seal. After maintenance, gradually restore water flow and check for leaks.

What to consider before purchase

• Confirm that your piping or fitting uses a 3/4" threaded connection compatible with inline strainers
• Determine whether coarse particle filtration meets your needs or if finer filtration is required
• Ensure there is an accessible location for periodic removal and cleaning of the basket

Usage recommendations

For reliable operation, inspect and clean the basket at regular intervals depending on water quality and particulate load; verify thread compatibility and use appropriate sealing material when installing to prevent leaks.
