TOTO ST243E#01 – Frequently Asked Questions

1) What else do I need to buy to install a TOTO Entrada toilet tank?
The tank ships with the tank-to-bowl gasket, tank-to-bowl hardware, and bolt caps. Everything else on the install is separate: the bowl itself, wax ring, floor mounting bolts, water supply line, and the seat. Worth staging all of that before the truck rolls if you're doing a multi-unit swap.
2) Does the TOTO Entrada tank meet WaterSense and California water efficiency rules?
Yes. At 1.28 gallons per flush it carries EPA WaterSense, and it meets California CEC and CALGreen requirements. That's the combination a spec writer needs for California work and for most green-building and rebate programs.
3) Can I buy just the tank if the porcelain cracked on my Entrada toilet?
Yes, the ST243E is sold as a tank on its own, in vitreous china, with the trip lever fitted and the tank-to-bowl gasket, hardware and bolt caps in the carton. As long as the bowl still in the floor is an Entrada C243EF or C244EF, you can replace the tank and leave the wax ring and bowl undisturbed.
4) Will the TOTO Entrada tank work with a 1.6 GPF bowl?
No. This is a 1.28 GPF tank matched to the Entrada 1.28 GPF bowls, C243EF and C244EF. Putting it on a bowl designed for a different flush volume mismatches the trapway to the water delivered, and the mounting geometry isn't a given either. Match the tank to the bowl model it was built for.
5) Is the trip lever on the TOTO ST243E tank on the left or right side?
Left-hand, and it comes chrome. That matters in a tight stall or an alcove where the handle side decides clearance, so check which way the existing handle faces before you order.
6) Why does the Entrada tank flush well on only 1.28 gallons?
It uses TOTO's E-Max system built around a 3 inch flush valve. The wider valve dumps the tank faster, so the bowl gets a strong flush out of 1.28 gallons instead of relying on volume. For property managers, the practical read is high-traffic performance without going back to a 1.6 gallon fixture.
