Backflow testing questions, answered

A backflow preventer is a valve assembly installed on a water line to stop water flowing backwards into the drinking water supply. If pressure in the system drops or reverses, whatever is on the far side of that connection — irrigation water, boiler treatment, chemicals, process water — can be drawn back toward the mains. The assembly is what stands between that and the potable supply.

Because it is a mechanical device with moving parts, springs, and seals, and it fails silently. A backflow assembly that has stopped working looks exactly like one that is working. Testing is the only way to confirm it still holds, which is why testing is required rather than optional.

Annual testing is the general standard for backflow assemblies, and some installations are required to be tested more frequently depending on the hazard and the property. The requirement that applies to your property is set by your municipality. If you have received a notice, it will state the deadline — send it to us and we will work to it.

The test itself is normally quick — often around 20 to 30 minutes per assembly once we have access to it and the paperwork is prepared. Finding the device and getting into the space it lives in is frequently the longer part of the visit, which is why access details help so much when you book.

Yes. Reporting requirements vary by municipality, and Eagle Eye submits the required test documentation through the applicable municipal reporting system on your behalf. You do not need to understand or navigate the reporting process yourself.

A failed assembly needs to be repaired or replaced and then retested. We will tell you at the time what has failed, whether it is repairable, and what it will cost before any repair work goes ahead.

Often, yes. We carry common replacement parts and rebuild kits, so many typical failures — fouled check valves, worn relief valves, perished seals — can be repaired and the assembly retested before we leave. Larger assemblies and less common devices sometimes need a part ordered in, and we will tell you that on the spot rather than afterwards.

Usually not. What we need is access to the assembly. If a caretaker, building manager, tenant, or concierge can let us in, most tests are completed without the owner or strata council present.

Briefly, to the line the assembly protects — normally a matter of minutes per device. Where that matters, such as a restaurant mid-service or a medical office, tell us when you book and we will schedule around it.

It depends on the number of assemblies, their size and type, and how accessible they are — which is why we quote rather than publish a single figure. Send us a photo of the device or your municipal notice and we will give you clear pricing before any work begins. You do not pay until the work is complete.

Failure to complete required testing may result in enforcement action, fees, or other penalties depending on your municipality. The specifics differ from one city to the next, so check the notice you received or ask us and we will point you to the right place.

Eagle Eye covers Greater Vancouver: Vancouver, Richmond, Surrey, Delta including Ladner and Tsawwassen, Burnaby, New Westminster, Coquitlam, Port Coquitlam, Port Moody, Langley, North Vancouver, and West Vancouver. If your community is nearby but not listed, ask — we will tell you straight away whether we can attend.

Yes, and a large part of the work is exactly that. We can work to your access procedures, coordinate with caretakers directly, and provide documentation in the form your records need.

Yes. Send the full address list rather than booking one at a time and we will group the testing into as few visits as the geography allows, complete repairs where we can, and handle report submission across the whole portfolio.
