Q and A

Q: What is the size of the diverter screw?

A: The diverter screw is female and has a diameter of 55/64 inch. The included adapter is a male-to-male type, 55/64 inch (21.8 mm) to 15/16 inch (23.8 mm). The U.S. quarter is 24.3 mm.

Q: I know the type (male or female) of my faucet aerator, but I don’t have a measuring tape. What can I do?

A: If you’d like, there are two Amazon products to help: one with 7 male-to-male adapters and another with 7 female-to-male adapters. These ensure you’ll find the right fit without precise measurements.

Q: My faucet has a 55/64 female aerator, but the diverter screw cannot reach the threads inside the faucet. What can I do?

A: You may need a faucet adapter extension (55/64 female to 55/64 male). Please refer to the User Manual for more details.
