Which backup sump pump should I get for my basement?
I'm trying to find a battery backup sump pump for my basement. I have a fairly shallow pit only about 17inches deep with stone under it preventing me from digging deeper. I have a high water table which causes my 1/2HP main pump to turn on often during heavy storms and the low depth of the pit means that the water can reach 2-5inches from the top of the pit even with the primary pump running. As a result, both the primary pump and backup float would be triggered, having both pumps running at the same time pumping water through the same 2inch PVC to the outside.
Two question I have are: 1) With large amount of water to be pumped (+3000GPH) what battery backup sump pump do you recommend. 2) Should I run a second PVC out the house as the discharge for the backup system or can my existing 2" PVC support both the main and backup sump pump running simultaneously.
