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.

I recently had a leaking outside water spigot that I couldn’t fix on my own so I decided to shop around and find a reliable plumbing company to assist me. Olympia Plumbing Technology in Olympia Wa. Answered the call. The technician I worked with was named Morgan who was absolutely professional and knowledgeable about the job! Morgan explained in great detail the job he would perform to fix my leaky spigot which lead to cutting into drywall to repair a poorly installed pipe during the home construction. As Morgan worked he explained the why’s on what he was doing and made sure I completely understood the issue and how he was going to fix it! After the job was over Morgan left the work area like his company was never there. Because of his hard work and professionalism I am recommending Olympia Plumbing Technology to all my family and friends! I would highly recommend this company to anyone looking for an outstanding plumbing service! Joe

Rafael was incredibly professional, very patient and left our washroom plumbing looking immaculate and functioning better than ever. We got same day assessment and fix, which was awesome. My experience was that this professional plumber was notably courteous and worked efficiently to take some 100 year old plumbing and make it modern functioning. What a blessing. Thank you Rafael. He a joy to work with.
