Exterior shut off valve required?


My system has a cracked outdoor shut off valve caused by a late winterization. I will be replacing the valve with either straight copper or another valve, however I would like to know if an additional exterior shut off valve is required?

When the system was installed a shut off valve was installed in doors just before the back flow preventer. Is there any reason another shut off valve was placed outside? Would it be feasible to just replace the valve with matching copper tubing?

Would love your thoughts on this, thanks! :rolleyes:

What kind of indoor backflow preventer is there? Such things are suspicious these days. What do you have against having an outdoor shutoff for the entire system?

Makes sense to have one, especially if something goes haywire when we're not home someone can shut off the water supply. Replaced it yesterday with a ball valve that has a bleed knob on it with success!
