Watts vs Wilkins Backflow Preventers

Looking for a backflow preventer valve and not sure which to pick between Watts and Wilkins backflow preventers? Both make some of the best valves on the market which mean it can be difficult to choose between the two when looking for a new backflow device.

Our team of experts reviewed the top valves from both companies to help you pick the best choice to meet plumbing codes and protect your water supply.

Watts or Wilkins (Zurn)?

Watts and Wilkins all make very similar backflow preventers that have almost the same build quality, features, and price point. Add in the fact that many homeowners only buy one valve in their entire life and things get even more confusing. The key to making the right choice is to set your price range and look for a valve that has the correct sizing and additional features you need for backflow prevention.

Watts Advantages

Watts makes a wide range of backflow preventers that work on water lines, sprinkler systems, irrigation systems, and other water lines to prevent backflow contamination incidents. They come with a number of features and fit almost any size line.
