Readings and a spec sheet
The technician measures your water, explains each number and writes a spec sheet with a price if anything needs doing.
Questions about getting in touch
Can I book online?
Booking is by phone so we can ask the three questions that decide the kit and the route. It takes two minutes at (408) 831-7890.
How soon can you come out?
Usually within a few business days, sooner if a route is already near you. We give you the earliest window on the call.
Is there a charge for the measuring visit?
We tell you the cost of any visit on the phone before you book. Nothing is added at the door.
Do you cover my city?
If you are in Santa Clara County between Palo Alto and Milpitas, very likely. Check the service areas page or just ask.
Can I call about a system another company installed?
Yes. Note the brand and model if you can. We service most major makes.
Ready when you are
One short call books the visit. You will leave it with your readings and a clear set of options.
