TOTO 9AU4077 – Frequently Asked Questions
1) What is the TOTO 9AU4077 part and what flow rate does it give?
It's a TOTO MR05 flow regulator for faucets, rated 0.74 GPM. It drops into the faucet to hold discharge at that rate, so it's the part you order when you want a low-flow faucet to meter correctly rather than run wide open.
2) What TOTO part number should maintenance order for the 0.74 GPM MR05 regulator?
Order TOTO 9AU4077. That's the manufacturer part number for the MR05 0.74 GPM faucet flow regulator, and it's the number to put on a stockroom card if you're carrying spares across a building.
3) My TOTO faucet is running too fast after a cartridge swap. Will this regulator fix it?
If the faucet takes the MR05 regulator, yes, that is the component that sets the flow, and 9AU4077 is the 0.74 GPM version. A missing or crushed regulator is a common reason a serviced faucet runs harder than spec. Match it to the flow rate your faucet is specified at, since the MR05 family is sold in more than one rate.
4) Is the TOTO 9AU4077 a single part or a kit with other faucet trim?
Single flow regulator, one part number, one configuration. It is not a cartridge kit and does not include aerator housing or seals beyond the regulator itself, so order any other wear parts separately.
