Blanco 203443 – Frequently Asked Questions
1) Will the Blanco 203443 disposal flange fit a standard 3-1/2 inch sink drain opening?
Yes. The Blanco 203443 waste flange is made for standard 3.5 inch drain openings, which is the normal cutout on kitchen sinks built for a garbage disposal.
2) Does the Blanco 203443 flange work with an InSinkErator garbage disposal?
It is built to work with most InSinkErator garbage disposals through a standard 3.5 inch drain opening. If your disposal mounts to a non-standard opening, it is not the right part.
3) What color is the Blanco 203443 disposal flange and what sinks does it match?
Model 203443 is the Soft White version, color-matched to Blanco SILGRANIT sinks in that color so the drain blends into the sink deck instead of showing a chrome ring.
4) Is the Blanco 203443 a full sink strainer or just the disposal flange?
It is a disposal flange, the metal ring and stopper that finishes the disposal opening at the sink. It is not a basket strainer assembly for a non-disposal drain, and it does not replace the disposal mounting hardware itself.
5) Can I leave water in the sink with the Blanco disposal flange, or does it only drain?
Both. The flange seals tight to hold water for prep or soaking, and can also be set to let water drain through while keeping food scraps out of the pipes.
6) I manage apartments with Blanco granite sinks. Can I standardize on this flange across units?
Yes, if those sinks are SILGRANIT with a standard 3.5 inch disposal opening and a Soft White finish. The 203443 is the Soft White match; other SILGRANIT colors need the flange in their own color to look right.
7) Is the Blanco 203443 flange metal or plastic?
Metal. It is a color-coordinated metal disposal flange, so the visible ring at the drain is a durable metal part rather than a painted plastic trim ring.
