    I needed an insulated jacket for my sprinkler valves. All I could find online was cheap quality and nothing 55" long. A trip to Backflow Depot in Rocklin proved to be a dream come true. I first spoke with Kenzie who was quite knowledgeable and helpful. Then the sales president came out to greet me and gave his ideas. And then the guy who actually makes them (Manny) came over to explain that my measurements would need to be adjusted in order for the jacket to fit. Thank God! Was he ever right. He added a few inches to the length and a couple inches to the height, allowing for the perfect fit. Manny then got to work and had my jacket very professionally completed within an hour! Exceptional craftsmanship and high quality materials. So good, it may outlive me! I cannot praise these guys and girl enough. And the price was unbelievably good. Thank you all. 👍

    I don't usually write reviews, but I feel this needs to be shared! I want to extend a heartfelt thank you to Backflow Depot. Recently, I was looking for someone to donate a generator and reached out to Jon Lotito. Although he didn't have the one we needed, he didn't hesitate to purchase one himself. The very next day, Jon took time out of his busy schedule to personally bring a generator—and a smaller one—to Del Oro High School. He even made a generous donation to the program, asking for nothing in return. A week later, Jon was back at the school repairing the backflow system that had been broken all summer. His commitment was truly incredible! When I asked once again how I could repay him, Jon simply said, "It's for the kids." Thank you, Backflow Depot, for your kindness and dedication to Del Oro High School! ❤️

    Gia and the team at TBD saved the day. I called and explained my situation and by the time I arrived they had a plan in mind. I followed their instructions and it worked out perfectly and saved me a bunch of money! Recommend them highly.

    I love working with the team at Backflow Depot. They respond almost instantly to requests, communicate throughout the ordering process on part(s) status, and have even gone out of their way to drop parts off same day as the order was placed.

    I've dealt with Jon, Jed, Jason and Cari — they're all great professional people!

    ★★★★★

    As soon as I reached out, Danny and the team were on putting together pricing for a cover I needed made. They stayed on top of communication and replied super quick! 10 out of 10 I would recommend! I know I'll use Backflow Depot for any future needs again.

Stock & pickup

Do you actually stock these parts?

Yes. We keep 1,000+ backflow repair parts, kits, assemblies and freeze bags on the shelf in our Rocklin, CA warehouse — we don’t drop-ship. If something is out of stock or has to come from the manufacturer, we’ll tell you and quote it.

Finding the right part

How do I find the part that fits my device?

Use our Repair Parts Finder: pick the brand, size and model and you’ll see only the parts that fit. Every assembly and repair-part page also lists the other parts for that same device. Still not sure? Call (916) 251-7071 with the brand, size and model from your device’s tag.

Why do some items say “Request a quote”?

Larger 2½" and up devices, enclosures and special-order items are quoted so a backflow specialist can confirm availability, shipping and pricing first. Add them to your quote, send your details, and we email you an itemized estimate — nothing is charged until you approve it.

Shipping & accounts

Where do you ship, and how long does it take?

We ship anywhere in the United States from Rocklin, CA. Standard shipping normally takes 3–5 days, and next-day shipping is available on domestic orders for an additional charge.

Do you offer accounts for contractors?

Yes. Approved business customers can buy on net terms and get a customer portal with their invoices and statements. Call (916) 251-7071 to set up an account.

Freeze bags

What freeze bag sizes do you stock?

We stock Sub Zero Covers standard freeze bags (made in the USA) in five sizes — 20×20, 24×24, 30×24, 36×24 and 42×24 — in green or tan, for 1/2"–2" devices. For 3" and larger or unusual devices we order a custom size: use our sizing tool or call (916) 251-7071.

Returns

What is your return policy?

Parts in resalable condition can be returned within 30 days of purchase. Some items that go back to the manufacturer can carry a restocking fee of up to 30%, and custom or special-order items can’t be returned once ordered. Return shipping is the customer’s responsibility, and refunds are issued after inspection. Full details: refund policy and return form.
