A small strip-center tenant might have a single assembly on the service line. A restaurant can have one on the main service, another on irrigation, and more protecting equipment like soda dispensers, dishwashers or chemical dispensers. Clinics, dental offices, salons, car washes and light industrial shops each bring their own hazards.

Because a test shuts off water downstream of the device, a test on the main service can close a business for a short time. The best plan is to know every device you have and schedule tests when they cause the least disruption.

A yearly plan for a business with several devices

Start of the year
Update the device list with locations, sizes and serial numbers.
When notices arrive
Match each notice to a device and note the deadlines.
Before booking
Agree with the tester on an early-morning or closed-hours slot if the main service will be off.
Test day
Tell staff water will be off and protect equipment that needs constant water.
After testing
Collect all reports, confirm filing and store them with the device list.

Records worth keeping for every device

  • Device type, brand, model and size.
  • Serial number and the supplier's device ID.
  • Location and what it protects.
  • Every test report with readings.
  • Repair records and parts used.
  • Any correspondence with the water supplier.

Questions for a commercial tester

  1. Can you test all of our assemblies, including any fire line, in one visit?
  2. Can the test be done before opening or after closing?
  3. If a device fails, do you carry common repair kits?
  4. Will you give us one report per device with the readings?
  5. Who will do the work, and are they employees or subcontractors?

Common questions

Is the landlord or tenant responsible for testing?

It depends on the lease and on whose name the water account is in. Sort it out in writing before the deadline.

Can we keep operating during the test?

Only if the device being tested does not cut water to what you need. Plan around the main service test.

A new piece of equipment was installed. Does it need protection?

Possibly. New equipment connected to drinking water can create a new cross-connection. Ask the supplier before or after installation.
