I have a basement which gets water in it during the wet season. There is also a floor drain connected to a field tile which backs up when it rains excessively. The problem here is when the floor drain backs up, the sump pump either runs nearly constantly or simply cannot keep up. The most extreme case was a few years ago when the water rose to a depth of 18", endangering the furnace & everything else, not good. The highest flow in which the pump runs constantly usually only lasts 8-10 hours. My pump is a 1.25" submersible. I have on hand a 1.25" pedestal pump which I was thinking of placing in the sump & setting the float to start only after the main pump can no longer keep up. Obviously I need check valves on both pumps, & would need to "Y" the pipes together into a larger, maybe 2" outlet pipe.
Question is, would pumping two pumps into the same pipe make them fight each other, affecting the flow or should I plan on just investing money into a larger submersible pump? Pipe is much cheaper than pumps, which is why I'd rather go this way.
