Welcome to Backflow Prevention Supply


We specialize in products for the backflow industry. We stock everything from test equipment to enclosures and are able to do special orders for just what you want.

Our specialty is stocking repair kits for all current makes, models, and sizes of backflow preventers and some that are not produced any longer.

Feel free to e-mail or click on the "contact us" link on the menu bar to request any information that you may need such as product specification sheets, repair and maintenance information, price quotes or availability if you would rather deal with a person instead of a computer.

You will not find on this web page a list of individual parts or repair kits. We have provided you links to the manufacturers websites, which most of them have. Just follow their instructions to download their repair, maintenance and specification sheets.

We also have most of this info on our List Prices and Info page that you can click on from the top of any page.

We offer the best price on the Mid-West 845-5!

$695.00 + shipping and taxes if applicable.

We want to earn your business!!  Check our pricing!  We are very competitive and often have better pricing than found elsewhere.  If you have not tried us give us a call.  We believe you will be pleased with the courtesy, respect and service we provide you.

Informative Links

Some of the manufacturers have some good  informational and educational material.  They are good sources to get many answers to your questions about backflow.  I would also recommend the University of Southern California's website for an introduction to cross connection control, definitions, and types of backflow preventers.
