Why Backflow Testing?

If your property has a maintained lawn, you should annually test your backflow prevention system. This ensures that your drinking water is safe and not contaminated by chemicals or fertilizers that might flow back through your sprinkler or irrigation system.

This testing is best performed by Master Plumbers with the appropriate RPZ Backflow Certification. At RW Dowding Plumbing, your backflow testing is performed by a certified Master Plumber, so that you can rest assured that your drinking water is safe and clean throughout the year.

We will definitely use R.W. Dowding Plumbing for all of our plumbing needs. We finally found an honest and professional plumbing company. They respond quickly and helped us with a major kitchen sink clog that many other companies could not fix. They showed up on time and completed the job quickly and thoroughly for a reasonable rate. We will be referring them to anyone we know who needs a plumber.

They were courteous & professional. They showed up on time & cleaned up when they were done. Good experience working with them.

I sent a photo of my gas line issue. He gave me quotes on two options. He recommended the less expensive. I decided that was the better option because it didnt involve cutting into drywall. He was late on his proposed timeline but let me know prior to that time. He was prompt for the changed time. He did extra work (moving the water line to my fridge closer to the wall and removing the no-tip for the previous range from the floor) so the range could be pushed in all the way so it was almost perfectly counter depth. Thanks Brad.

They are great people, delivery great service, they are always on time , and clean up after themselves.

They're very thorough. They look down the road for issues and think through everything.
