How to replace a Febco 765-1

My PVB got hit hard this winter. Not only did the Bonet and Poppet break, but one of the ball valves has a crack in the housing. But there is no union in the line. The pipe comes right out of the house into the inlet ball valve and the outlet ball valve connects to a pipe that goes straight down into the ground.

Did the original installer mess up? Is there a way to remove this thing that I'm not seeing

this is typical installation....if in doubt...have an irrigation repair tech do the work....

99% of installs have ZERO unions....

So, if there is no union, how does one get it out to replace?

This might sound stupid, but is the 765-1 the same as the 765-100 PVB?

Thanks Tom. I have a Febco 765-1 that needs a few parts replaced and I found out that it is cheaper to just buy a whole new PVB rather then get the parts replaced. I found the 765-100 for a decent price and I just wanted to confirm that it was the same as what I currently have. Thanks again.

To all who actually test and repair backflow assemblies you should know by now that anything with the name "febco" is nothing better that a 8 lb. brass paper weight. Lets all do eachother a foavor and never install or replace a febco piece of junk again.

Do you have a suggestion of something better I could purchase to replace the Febco 765-1? I was only going to replace it with another one because that is what is there already. If there is something better I should get I would love to get your input.

If you winterize it properly, you can live with the Febco. Any PVB will not survive a winter with it filled with water.
