Frequently Asked Questions

Q: What size floor drain is this magnetic drain core compatible with?

A: This floor drain core fits drain openings with an inner diameter of 32mm to 45mm, making it compatible with most standard bathroom, kitchen, and laundry room floor drains. If you're unsure, measure your drain's inner diameter before purchasing.

Q: How does the magnetic self-closing mechanism work?

A: The drain core uses a gravity-activated flap that opens to a full 90° angle when water flows through, allowing for fast and efficient drainage. Once the water flow stops, the flap automatically closes and seals shut, blocking sewer gases and insects from entering your home.

Q: Is the filter basket easy to clean?

A: Yes! The grille filter basket is fully detachable. Simply lift it out, rinse away any hair or debris under running water, and reinsert it. No special tools or cleaning products are required.

Q: Will this drain core slow down my drainage speed?

A: No. The 90° gravity-open flap design ensures full, unobstructed flow when water is present, so drainage speed is not compromised. The seal only engages when there is no active water flow.
