Backflow is the undesirable reversal of flow of non-potable water or other substances through a cross-connection and into the piping of a public water system or consumer’s potable water system. There are two types of backflow: back pressure and back siphonage.
A cross-connection is any temporary or permanent connection between a public water system or consumer’s potable (drinking water) system and any source or system containing non-potable drinking water or other substances. An example is the piping between a public water system or consumer’s potable water system and an auxiliary water system, cooling system, or irrigation system.
Yes, We handle all paperwork and submissions to the regulatory agency. Please be aware that test reports will not be submitted to your local municipality until payment has been made in full. Payment delays may result in late test documentation filing with your village. Failure to file a passing test report has been known to result in water shut off and/or fines.
We can do either but most customers prefer us to email the invoice. On the same day shortly after your appointment is completed you will receive an invoice from (Intuit Quickbooks). Please make sure that you received the Work Order confirmations previously and notify us if you did not or if you do not have an email. If no email is provided we will leave a copy of the Work order but ask you to call 312-638-9878 to verify the amount and details before payment.
For (1 device) not very long however please make sure the area is clear and accessible during the time and date of your appointment. Double check if there are any additional instructions to minimize down time (contact phone numbers, hours of operation, lock box codes, alarm panel codes and keys, etc.)
Backflow devices installed inside can be tested anytime, however someone must be present for access to the device.
Perhaps the worst part of our job is notifying our customers when their device has failed its inspection. This can happen to brand new or old devices for many reasons, such as… Debris is lodged in the device and either fouled or damaged the internal rubbers, freezing conditions have cracked or damaged the device, the rubbers and o-rings are old and dry rotted. In accordance with our licenses, we have a moral and ethical obligation to do what is best to protect our water supply. The good news is we have the most competitive rates and our quality of workmanship is world-class. We also offer a price match commitment; we will try to beat any other written offer you receive! On the same or following business day, you will receive an email with an invoice for your initial test. You can click on the link and pay with a credit card, mail in a check or pay by phone. If you paid the technician, then your payment will be processed that same day. Your initial test fee and (submission fee if applicable) that was paid will be applied to the repair quote you will be receiving in the next day or two. When the quote is accepted and the work performed, the process repeats. Once the repair payment is received, the results will be submitted to your regulating authority.
No, Irrigation devices installed outside are seasonal and require coordination with your lawn irrigation company and/or property owner. The device must be installed and the water turned on up to the backflow for us to perform the test.
No, this is usually done by the homeowner or by the irrigation company as part of your seasonal contract.
Yes, We have customers that get up-set because previous plumbers have tested their unapproved device, resulting in confusion and putting the customer at risk for liability and breaking the plumbing code. Please see the highlighted plumbing code below for your reference.
Usually No, the timers solenoid valve is after the backflow so it won’t effect the test. In very rare cases the solenoid valve is before the backflow in which case someone must be home to turn it on when we are ready. This should be communicated by the owner upon scheduling the test.

4) Atmospheric vacuum breakers shall be installed with the critical level above the flood level rim of the fixture they serve, and on the discharge side of the last control valve of the fixture. No shut-off valve or faucet shall be installed beyond the vacuum breaker.
5) No in-line double check valve backflow preventer assembly (DCV) or reduced pressure principle backflow preventer assembly (RPZ) shall be located more than 5 feet above a floor, or be installed where it is subject to freezing or flooding conditions. After installation, each DCV and RPZ shall be field tested in-line in accordance with the manufacturer’s instructions by a cross-connection control device inspector before initial operation. (See subsection (b).)
6) A dual check backflow preventer with atmospheric vent assembly shall not be installed where it is subject to freezing or flooding conditions.
7) Closed water systems with hot water storage shall have a properly sized thermal expansion tank located in the cold water supply as near to the water heater as possible and with no shut-off valve or other device between the heater and the expansion tank. Exception: In existing buildings with a closed water system, a properly sized pressure relief valve may be substituted in place of a thermal expansion tank. For closed water systems created by backflow protection in manufactured housing, as required in Section 890.1140(i), a ballcock with a relief valve may be substituted for the thermal expansion tank.
