Best Backflow Preventers in Minneapolis MN

My wife and I just moved into our first home. I went to replace the shower head in the master bathroom and the whole arm came off. I tried calling three other plumbers only to get voicemails and haven't yet heard back from two. John answered right away and was at our house within 30 minutes of answering and had us back up and running one hour after I called him. Will absolutely keep using John's services!

Helpful, had what I needed.
