What Causes Backflow in a Plumbing System?

Backflow usually happens when water pressure drops unexpectedly, causing water to reverse direction. This can pull contaminated water from irrigation lines, appliances, or other sources back into your home’s clean water. It’s often triggered by things like a burst main or firefighting efforts nearby.

Do I Really Need a Backflow Prevention Device?

If your home has an irrigation system, fire sprinkler, or other cross-connection points, a backflow prevention device is not just smart — it’s often required by code. These devices stop dirty water from mixing with your drinking water supply.

How Long Does Backflow Testing Take?

Backflow testing typically takes less than an hour for most residential systems. Our licensed plumbers handle the inspection, document the results, and submit any required paperwork to the local water authority.

What Happens if My Backflow Device Fails?

If a backflow preventer fails, it needs to be repaired or replaced immediately to avoid water contamination. Olympic Plumbing Technology offers fast service and can make sure your home stays protected and up to code.

Called Olympic Plumbing at 11:00 am with unknown leak problem. They got somebody to my house in 3 hours, correctly diagnosed the problem, then promptly fixed the problem as Nick had the parts in his van. Super happy! Will use these guys again!

I was graced by ye almighty with the presence of Saint Nick G. He was jolly. He was jovial. He brought tidings of comfort and joy to my free inspection for a water leak. He definitely put Olympic Plumbing Technology on the nice list. He unfortunately did not accept my offering of milk and cookies but that is ok as he was very professional and pleasant to work with. I have worked in the trade industry for awhile and you can tell when you have an honest and hard working person in your presence. I appreciate you and OPT. Im down with OPT! Every last homie!

Nate was quite professional, efficient and technologically savvy to look at pics of my existing bathroom on Zillow while we talked about a renovation.

The technician Raphael was great. But unfortunately the prices were obscene. They wanted $861 to replace a kitchen faucet. I declined and will have a friend do it for me. But the technician was really good about trying to solve my problem, and did a good thorough inspection of all my plumbing.

Leak occurred from previous work performed. Dylan replaced the faulty brass fitting at no charge which fixed the problem. Again, Olympic plumbing provided prompt, professional, courteous, and respectful service. We highly recommend this company!

Nate, from Olympic Plumbing, did an outstanding job with the installation of a water heater for our home. He was professional, knowledgeable and wasted no time on his arrival. He explained the process, provided a detailed description of the work, a cost estimate and answered all questions presented to him. I was very pleased with the work that he did. I would recommend to anyone that Olympic Plumbing be on the top of their list should they need plumbing work accomplished.

Raphael provided the best (no exaggeration) plumbing consultation I have ever received in my 60+ years of life. He was personable, thorough and did not complete his search for the exact products and modifications we were seeking until he found them. His quote took less the an hour, including the products we needed. He also did a full plumbing inspection and found our new, one-and-half-year -old home had a plumbing issue that did not meet code, resulting in recommending in the appropriate 'fix'. Finally, he assured us that he would do the work, further assuring the products and modifications were done to our specifications. I cannot expect more than that. I recommend Olympic Plumbing and Technology for everyone needing plumbing consultation and services. We will only use this company in the future.

Great experience with Brandon and his crew, thank you so much! We did a complete replacement of all plumbing in our business and it was a big job, over 3 days, really happy with everything. Quotes came in significantly lower from this business vs others in the area and their level of knowledge also seemed higher.
