The New Auto-Flush Kit For Compatible TOTO Toilets

The TOTO Auto Flush Kit is an easy to install upgrade for compatible WASHLET+ T40 toilets.

This model is designed to work with single flush 1.28 and 1.6 GPF WASHLET+ T40 toilets only.

When paired with the corresponding WASHLET+ toilet and Auto-Flush compatible S7A 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.

Works great!

Installs easy and works as expected.
I have the TOTO S7 with a single flush Drake toilet. The S7 was trying to do a light flush when both seats were lifted. Had to call TOTO support to reset the S7 for single flush and all is well.

The steps provided by support were not in a manual that I could find.

Steps to reset S7 for single flush:
1. Hold Front Wash and + for 10 seconds
2. Press - > + > - (flashes twice, 2 long beeps)
3. Hold Front Wash and + for 10 seconds
4. Press Rear Wash > - > Rear Wash (Flashes twice, 2 long beeps = Complete.)

Premier Bidets - Excellent Service and Communications

We purchased a TOTO Auto-Flush Kit THU857 for Washlet S7 and S7A - Single Flush Toilets from Premier Bidets. I was looking for a brief explanation on the product and installation. The person who answered the phone was easy to speak with, and provided a detailed explanation of the product being purchased. The service and communication was excellent. I would definitely purchase from them again.
