Damaged pressure vacuum breaker
The metal backflow preventer valve at my parents house has cracked on the face of it from freezing I'm guessing, my dad jb welded the crack that is about 2" long today and insists it should be fine. I've read elsewhere that running the sprinkler system with a damaged backflow preventer could cause contaminated water to work its way back into the drinking water which is obviously not good. Any thoughts on if this type of "fix" will be OK?
Thank you.

My state requires any home with municipal water and lawn irrigation to have the backflow preventer valve tested by a certified technician annually at a cost of $60. I am sure your father can find a certified technician to test the valve. The other alternative is to replace the valve. In my opinion, either option is a small price to pay compared to possible medical costs if the water gets contaminated.

Thank you for the replies, I have said from the start it should be replaced but my dad can't be told anything as he feels he knows it all. My largest concern is that contaminated water ends up in the water softener system and then into the drinking water. I've atttempted to explain that trying to save the money on the new backflow preventor could cost not only a new backflow preventor but also having the water purification company out to have to service the softener or clean the lines in the house but he doesn't like to listen.
Does anybody know for sure if there is a good chance of the water in the sprinkler lines ending up back in the house's water system when the housing on this backflow preventor being cracked? I had only read that this was a real concern somewhere else and I don't think the guy was using a proper backflow preventor.
Thanks again everybody for taking the time to post.

At the worst.... the repaired crack will leak.
I don't see the crack inhibiting the functioning of the valve.
