Zurn Wilkins 34-950XLT2 3/4" 950XL Double Check Backflow Preventer

Was required to install one of these at my business by the local water authority - no problems at all - after installation, I had it tested/certified (also required by the township), and passed with flying colors

Higher quality than most I have seen and used. One of the petcock was machined poorly and leaked. I called the manufacture direct and they instantly shipped me a new valve at no cost. Highly recommend the valve company and the representative.

seems to work ok.

This back flow valve works as advertised and it is repairable. The cheap ones don't last.

I got it fitted to my house in little time. Just gotta see if it'll pass inspection now! Update later!

Installing this for irrigation, sure beats all other prices and delivery times. Why would i pay double plus and wait weeks for delivery from another vendor

Worked perfectly

Worth the price, nothing special but it doe's the job. Very small and short ( that is what I was looking for), but the self is very handy.

Great so far. Easy to install with very clear instructions, provided you have some basic plumbing experience. So far it has made it through 1 season of use in a residential sprinkler system. Not expecting any issues with freezing since I chose to install it indoors.

High quality. No way for me to function test it but the quality is great.

Easy to install. Great for my underground irrigation system.
