People in my town, due to Ida, asking about backflow valves. In my home I have a JR Smith 7150. You can't really rely on the plastic one-way flapper. It also has a spade-type manual gate valve turned by a wheel. You have to make the decision whether and when to shut down your waste discharge. I know there are others. Anyone have any experience with the expensive 4" Deringer 20X Double Check, or others you would recommend? https://backflowdirect.com/4in-deri...QkoiwzETk_6qBsRmZtHuCysYqaphwHIwaAmGxEALw_wcB
