A: On municipal water, no.
On well water, yes — and it needs to happen before you order. Your water has to be tested, confirmed potable, and the full results sent to us for approval before we can move forward with your Refill Station.
Two approved tests:
You order and pay for the test directly, then send us the complete results — the full report, not a summary — at support@drinkflowater.com. Both are mail-to-lab kits and take about five business days at the lab once your sample arrives, so allow two to three weeks from ordering the kit to having an approved result. Worth starting early.
Either way, water pressure is worth knowing. Your FloWater Essential is designed for 50–100 psi and runs most effectively at 70. Above 100 psi, a pressure regulator needs to go in the supply line, and damage from pressure outside that range isn't covered.
