Backflow occurs when a sudden drop in water pressure causes contaminated water to flow backward into the clean municipal water supply. This reversal can happen due to a broken main city line, heavy fire hydrant use, or other unexpected fluctuations in public water pressure. To prevent this, residential and commercial properties are equipped with backflow prevention devices. Lovett Plumbing provides comprehensive backflow testing to ensure these critical safety valves are functioning correctly and actively protecting your drinking water.
Our technicians apply the same rigorous, high-level technical proficiency used in large-scale commercial environments directly to your home plumbing system. For a mandatory compliance notice from your local water authority or a routine inspection for a new property, we manage the entire process. From meticulously testing the internal check valves to filing the necessary paperwork directly with city officials in Portland, Beaverton, Vancouver, and surrounding communities, we handle it all with absolute professional accountability.
If you are looking for a highly qualified, certified backflow tester near me, Lovett Plumbing brings over two decades of localized expertise to every property we visit. We focus on delivering efficient results and clear communication for property owners working through compliance requirements.
Maintaining compliance with local water bureaus requires specific diagnostic procedures and precise record-keeping. Our team is fully equipped to handle every aspect of backflow prevention for both residential and commercial properties.
In Oregon and Washington, municipal water purveyors mandate that all backflow assemblies are tested annually by a state-certified professional. Our technicians arrive with specialized, calibrated pressure gauges to test the internal seals, springs, and check valves of your assembly. We verify that the device meets all performance standards required to block back-siphonage and back-pressure.
If a device fails its annual test, it does not necessarily mean the entire unit needs to be replaced. Often, internal components degrade due to hard water, sediment, or standard wear and tear over time. Lovett Plumbing provides precision plumbing repairs, targeting only the necessary internal rubber seals, O-rings, and springs. We service major assemblies and utilize replacement parts from trusted manufacturers. Every repair is backed by our strict 1-year warranty.
When a backflow assembly is severely damaged, outdated, or no longer meets the current plumbing code requirements, a full replacement is required. Our technicians perform code-compliant installations for both domestic water lines and irrigation systems. We properly size the assembly, ensure adequate drainage clearances for Reduced Pressure Zone (RPZ) devices, and handle the initial certification testing required to log the new device with the city.
Ready to secure your water supply?
Maintaining a functioning backflow prevention system is about more than just checking a box on a municipal form; it is a critical step in safeguarding public health and preserving your property’s plumbing infrastructure.
Have a compliance letter with a fast-approaching deadline?
We have streamlined our service process to make annual compliance as simple and efficient as possible for property owners in Portland, Tigard, Lake Oswego, and across the PNW.
Contact our dispatch team to book a convenient time for your inspection. We emphasize clear communication, ensuring you know exactly when our technician will arrive at your home or business. Because backflow testing typically requires a brief interruption of your water service (usually around 15 to 30 minutes), we schedule the visit at a time that minimizes disruption to your daily routine.
Upon arrival, our certified technicians perform a visual inspection of the assembly to check for obvious signs of external damage, leaking, or improper installation clearances. We then attach specialized, commercial-grade differential pressure gauges to the test cocks on the device. By isolating the water line, we evaluate the exact pressure levels and check that the internal check valves close tightly against reverse flow.
If your system successfully meets all required pressure thresholds and passes the test, we immediately certify it. Lovett Plumbing takes the extra step of submitting the required compliance reports directly to your local water authority, including providers in Hillsboro, Clackamas, Oregon City, and Vancouver. This saves you the hassle of dealing with confusing municipal paperwork.
If the device fails the inspection, we never leave you without a solution. We will clearly explain the exact mechanical issue and provide a highly transparent quote for repair or replacement. Because our trucks are fully stocked, we can often perform the necessary repairs on the spot, re-test the unit, and finalize your compliance documentation in a single visit.
Ensuring compliance usually takes less than an hour from the moment our technician arrives.
Since 1997, Lovett Plumbing has operated on a foundational principle: homeowners deserve the same level of technical precision, specialized equipment, and rigorous accountability that large-scale commercial facilities demand.
Backflow preventer testing leaves no room for guesswork. Contaminated water presents a serious health and safety hazard. We require our technicians to undergo continual training on the latest local codes and regional water authority standards. This deep expertise allows us to service properties ranging from single-family homes in Gresham and Sherwood to large multi-family residential complexes and commercial spaces in Salem and Eugene. No matter the scale of the plumbing system, we guarantee 5-star service and stand behind our work with a solid 1-year warranty.

Dan from Gladstone was prompt, courteous, and thorough in diagnosing our plumbing issues and finding a good solution. He was experienced and knowledgeable and offered good advice for maintaining our bath/shower plumbing going forward.

Brandon was a lifesaver. In just two hours, he figured out what our rental maintenance team and another contractor couldn’t. He found the leak was coming from upstairs. He didn’t stop there either. He cleaned up the mess left behind, helped reduce the active leaking, and made sure everything was handled as well as possible on our end.

Right before Christmas, we discovered a leaking water main when our water bill was more than 3x the same period last year. On short notice, Lovett was able to get Doug out to make an initial assessment, then Brian got me an estimate without delay. Foreman Steven showed up Monday morning and was able to head off potential delays by thinking creatively. He set things up nicely so that we had water running again by late Tuesday morning!

Lovett was dispatched to fix a leaky bathtub faucet in our rental home, and the service I received was top notch! Jill reached out to me quickly and was able to schedule us for the next day. Our plumber Cameron was friendly, gave us heads-up when he would be here so I could secure our furry friends, and was able to resolve the issue no problem! I definitely would recommend Lovett for your plumbing needs.

I had a kitchen sink issue. Lovett came out, and Greg was my tech. Very smart and informative. He was efficient and clean. He answered questions. And my sink was cleared up in an hour. I was so thankful for the service and reasonable price. I will use them again for any bigger projects that might come my way. I recommend this Company fully.

I hadn’t lived in my new place for ten days when a pipe broke. Dan came first thing the next morning, cut a 5×10 hole in the wall and capped off the pipe – problem solved! He also took the time to turn down the heat on my hot water heater, and explain the plumbing system to me. I wish I could give him another star.
Portland, OR
I had a major issue with my well system and was completely without water. After calling many companies who all said they couldn’t help, I reached Ken Williams at Lovett. Ken was immediately attentive, kind, and incredibly knowledgeable. He helped me troubleshoot the problem and quickly got their equipment scheduled and out here to get the repair underway. His professionalism and genuine care made all the difference.

Tyler came out today to inspect/replace my garbage disposal and it was such a great experience! He made the interaction very personable. He also explained different things about the process along the way and I really appreciated that along with how clean he was. He wore shoe covers and completely cleaned up the underneath of my sink as well as the yuckies in the bottom of my sink. Overall, I highly recommend!!

Backflow testing is a standardized plumbing inspection that verifies your backflow prevention device is working properly. A passing test means contaminated water, such as water mixed with lawn chemicals from irrigation systems or stagnant water from pools, cannot reverse direction and contaminate the public drinking water supply.
In most municipalities across Oregon and Washington, backflow testing is legally required once a year. Your local water provider will typically send a notification letter to your address when it is time to schedule your annual test. Failure to test the device can result in fines or suspended water service.
Yes. Lovett Plumbing is fully licensed and certified to perform backflow preventer testing across the wider Pacific Northwest region. We maintain active certifications and compliance standards required for testing in Portland, Beaverton, Eugene, Vancouver, and the surrounding metropolitan areas.
If your device fails, it indicates that the internal seals, springs, or check valves are compromised and are allowing water to slip backward. Our technicians are fully equipped to perform precision plumbing repairs or, if necessary, replace the entire unit on the spot to quickly restore your system’s compliance.
In many cases, if your backflow assembly is located outdoors (such as an irrigation backflow preventer) and is easily accessible without locked gates or dogs in the yard, you do not need to be home. However, the testing process does require a brief shutoff of your water. Our dispatch team will confirm whether your presence is required when you schedule the appointment.
The testing procedure itself is strictly diagnostic and will not alter your water pressure. However, if your device is heavily calcified, failing, or partially blocked, replacing the internal components during a repair can occasionally improve flow rates. If you are experiencing broader water pressure issues, our team can perform leak detection or professional drain cleaning services to identify the root cause.
These are the three most common backflow assembly types for residential and light commercial use. An RP (reduced pressure principle assembly) provides the highest level of protection and is required on high-hazard connections. A DC (double check valve assembly) is used for low-hazard applications such as lawn irrigation on a standard city connection. A PVB (pressure vacuum breaker) is common on residential sprinkler systems and must be installed above all downstream outlets.
Yes. Irrigation and lawn sprinkler systems are one of the most common applications that require a backflow assembly because the sprinkler heads sit in soil that can contain fertilizers, pesticides, and other contaminants. Oregon water providers require these assemblies to be tested annually. If your irrigation system has a backflow device, the same annual testing rules apply as with any other assembly on the property.
Call Lovett Plumbing at 971-267-5677 to schedule your test before the deadline on the notice. The letter typically gives you a set number of days to have an OHA-certified tester complete the inspection and file a report with the water provider. We handle the test, complete the required report, and submit it directly to your water purveyor so you do not have to track down the paperwork yourself.
