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.
