Good product...bad gaskets.

I have found that every couple weeks the seals on the backflow will start to leak. I've tightened over and over, and the issue persists. Product is great quality and easy to use, but the gaskets don't do their job.

Works Flawlessly

I recently changed the back flow preventer and autofill combo on my 32 year old Burnham boiler. The Caleffi 573 shipped very fast, was well packaged, and included a good set of instructions. My knowledge of boilers is limited yet, installing this combo was no problem and it works flawlessly. There is also a great instruction video I recommend you watch.

Caleffi

Hands down the best combo BFP / PRV I have ever installed . Advice - a must , any caleffi products that have fiber gaskets , let them soak in water for a couple of minutes before installing .

nice product!

Needed this for an auto-feeder for my boiler. Nice unit, works great. Use plenty of teflon tape and crank on those compression nuts and you should have no problem
