Frequently Asked Questions

What is the Flex Strainer and how does it work?

The Flex Strainer is a 2-in-1 sink strainer and stopper that fits standard 3.5" kitchen drains and garbage disposals. It catches food scraps and debris to prevent clogs while allowing water to drain freely, and can also seal the drain when you need to fill the sink for soaking or hand-washing dishes.

What makes the Flex Strainer different from traditional basket strainers?

Unlike rigid metal basket strainers, the Flex Strainer features flexible, BPA-free construction that's easier to remove, clean, and reinstall. Its 5.25" width provides complete drain flange coverage, and the dual-function design eliminates the need for separate strainers and stoppers.

Will the Flex Strainer fit my sink drain?

The Flex Strainer is designed to fit most standard 3.5" kitchen sink drains and garbage disposals, including popular brands like Kohler, Kraus, Blanco, Elkay, Moen, and others. It works with undermount, farmhouse, single-basin, double-basin, and RV sinks.

How does the Flex Strainer help prevent clogs?

The strainer catches food scraps, peels, vegetable debris, and other particles before they enter your plumbing system. This prevents buildup in pipes and garbage disposals, reducing the need for chemical drain cleaners and plumber visits while keeping your kitchen running smoothly.

What are the best uses for the Flex Strainer?

Perfect for everyday dishwashing, meal prep cleanup, vegetable washing, and filling sinks for soaking pots and pans. It's ideal for homes, apartments, RVs, rental properties, and any kitchen where you want to protect drains and maintain flexibility between straining and stopping.

Is the Flex Strainer Made in the USA?

Yes, the Flex Strainer is proudly Made in the USA with high-quality, BPA-free materials. American manufacturing ensures consistent quality control, durable construction, and support for domestic jobs while meeting strict safety and environmental standards.

How durable is the Flex Strainer?

The Flex Strainer is constructed from durable, flexible polypropylene that resists wear, discoloration, and cracking. It's designed for daily use and can withstand hot water, dishwasher cycles, and regular handling without losing its shape or effectiveness over time.

Is the Flex Strainer easy to use and clean?

Extremely easy—simply place it in your drain, and it stays in position during use. To clean, lift it out, dump debris into the trash, and rinse or place in the dishwasher. The flexible design makes removal and cleaning faster than traditional rigid strainers.

Can I use the Flex Strainer in different types of sinks?

Yes, the Flex Strainer works in stainless steel, granite composite, fireclay, farmhouse apron-front, undermount, drop-in, workstation, bar, prep, and RV sinks—as long as they have a standard 3.5" drain opening. Its universal design makes it versatile across kitchen types.

What pack sizes are available for the Flex Strainer?

The Flex Strainer is available in three options: 1-Pack (single strainer with stopper), 2-Pack (two complete units), and 3-Piece Set (one strainer with stopper plus a bonus strainer). Multi-packs offer better value for homes with double sinks or for keeping spares on hand.
