I've now endured 2 sewer backup issues over the last month due to storms. I've done research and was told a check valve would be the best solution along with removing my toilet, sink and shower from the basement. I've also been told check valves are not the best solution because waste may get caught in it keeping it from closing properly all the time. Are check valves as good as most people claim or not? Also, other than an overhead sewer line which is very expensive, what are some solutions that might help? I really need some help. I've got a new baby on the way and my house smells awful, never mind the constant disinfecting.
