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.

Gaige was incredibly patient he went above and beyond to restore hot water to our home. He had wonderful customer service was never pushy to sell us a new unit and spent hours trying to fix the existing one. We ended up having him install a tank less water heater and he did a really great job making it look nice and showing up when he said he would which is rare these days.

Both Sarah's in the office and Nick were absolutely great. They were willing to come out to my house which is out of their typical area. Nick arrived on time, was very professional and diligent.

Nate was very helpful. We have old polybutylene PEX and the Shark Bite end cap did not stem the water flow after I installed. Nate suggested that I try and find an end cap with the polybutylene fitting. I tried every big box, plumbing supply store and hardware store I could think of - to no avail. Nate fixed it and we're good now.

We had a toilet leaking from our upstairs bathroom into our downstairs bathroom. Rafael did an excellent job explaining what was going on and fixing the leak. While he couldn't fix the rotting wood, he did refer us to a company that could. Later in the day we did receive a call from the other company which means he followed through on the referral! Rafael was very professional and thorough with his work. We even asked about a second potential leak that he looked at and we did find is a slow leak that will be fixed. I plan to use this company again in the future if we need any plumbing services.

I received exceptional service from the time I called the company. Corbin arrived on time and immediately saw the faulty plumbing issue (from a previous shower installation). He had all the necessary parts in his van and completed the new pipe installation. Thank you, Olympic Plumbing!9

The technician sent over was experienced, friendly, and so informative in explaining what he identified. He fixed a drain blockage located in my inlet baffle and also provided helpful tips on steps we could take to mitigate future blockages. Highly recommend this company and will be using them again for any future plumbing needs! Thank you Steven S for your quality service!
