I currently have a water heater in a finished basement that is from 1996. It still works fine, but I think its coming to the end of its life cycle as I am seeing some corrosion in certain places and slight dampness along the floor around it. I want to go ahead and get it changed out in order to avoid any kind of water damage down there. Since I am gonna have it changed out, I'd like to maybe put some sort of water heater auto shut off valve device in the supply line since its gonna have to be cut anyway. I figure this is the best time to have it installed. Some I have looked at include the following: - Floodstop - Water Cop - Floodsafe - WAGS valve Some are more expensive than others and I'm hearing/reading about some other matter related to these devices. Can anybody recommend another device that will do the same thing. Or any other advice when having one put in?
