The TOTO Auto Flush Kit is an easy to install upgrade for compatible WASHLET T40 toilets. This model is designed to work with dual flush 1.28 GPF and 0.9 GPF WASHLET toilets only.

When paired with the corresponding WASHLET toilet and Auto-Flush compatible WASHLET, the Auto Flush kit provides a hands-free automatic flush after every use. No need to touch buttons or handles, and never worry about someone forgetting to flush.
