When I replumb my washing machine drains and supplies, I was lookinag putting in a manual Time Out Valve that comes with attached hammer arresters. My supply shut offs are in need of replacing along with the rubber washing machine supply hoses. So decided to put new shut offs, with new Stainlesss supply lines to the washer. The system never had a safety valve, and have considered the Time Out. I realize you can go with an electronic shutoff, but would you reccommend the Time Out, considering, we never had a safety valve to begin with, been lucky so far. Thanks
