Q and A

Q: How do I find the right adapter for a female-threaded faucet aerator?

A: First, identify your aerator’s thread size by comparing it with a list of common aerator sizes, which can be found on this page. Once you know the size, search on Amazon using the following keyword format:

“faucet aerator adapter [SIZE] female to 55/64 male”

Replace [SIZE] with your aerator’s thread size (e.g., “3/4”) to find compatible adapters.

Replace [SIZE] with your aerator’s thread size (e.g., “3/4”) to find compatible adapters.

Q: Diverter screw won’t reach threads in faucet with 55/64 female aerator – what can I do?

A: You may need a faucet adapter extension (55/64 female to 55/64 male). Click here to check it out on Amazon.

Q: How do I know if my faucet has enough water pressure for a water flosser?

A: Try the following tips:
1. Use a Pressure Gauge (if available): Attach a gauge to your faucet; typical household water pressure is 40–60 PSI.
2. Or Measure Flow Rate (Without a Gauge): A faucet with 1.5–2.2 GPM should fill a one-gallon container in about 45 seconds.
3. Inspect the Faucet: the valve under the sink is fully open.
4. Test Another Faucet: Connect the flosser to a different faucet to compare performance.
