I would like to install a good quality battery back up sump pump. The existing sump pump is ½ hp sewage pump connected to a schedule 40 pipe. I have yet to find a battery back up sump pump that has a tee fitting for a schedule 40 pipe. So have resigned myself to just get a good battery back up sump pump and connect it in to the existing schedule 40 line if possible or just run a second line.
Basically what is a good quality reliable manufacture of back up pumps and what features are needed insure it will work when needed???
