Sigma Lavatory Faucet Cartridges

Replace Both Hot and Cold Cartridges? If your faucet is over 15 years old and you need to replace either the hot or cold water cartridge, we recommend replacing both cartridges at the same time. Over time, both cartridges experience similar wear and tear, so if one has failed, the other is likely to need replacement soon. By replacing both cartridges at the same time, you can avoid the inconvenience and labor cost of a second repair in the near future. This proactive approach saves you time, reduces labor costs, and eliminates the hassle of dealing with repeated maintenance.

We offer a bundle of the hot and cold cartridges that costs less than buying both cartridges individually. We also offer free shipping on the bundle.

COUNTING SPLINES A quick way to count the number of splines (ridges) is to count half of the ridges and multiply times two. Or count one fourth of the ridges and multiply by four.
