m53 sump pump zoeller specificationglycolic acid walmart

I want to say this pump is at least 30 years old. After a big rain, it is not uncommon for the flow of water coming in to be 2-3" deep. every hour for maybe 5 seconds max. Please give our experts up to two business days to respond. It has a 1.25" Pvc discharge pipe tying into 4" pipe that carries the water into a lake behind our home. I installed the Zoeller M53 with the recommended 1 1/2" Zoeller check valve. Drill the hole at a 45-degree angle so the hole is pointing toward the bottom of your sump basin. Sort of worried it might fail and flood the basement. In that case, your best defense is a higher output. The weep hole will help to prevent any air lock within your discharge pipe between the pump and check valve. Would you recommend a 1/3 hp or 1/2? Since M53 have a built in air relief hole do I need to drill a hole into my PVC pipe? That answer would be based on how much water you feel you would need to pump during a power outage. Can you raise the vertical float switch to accommodate a higher water level in the sump pump pit on this Zoeller submersible sump pump, if so, how?
