Just go to Tractor Service Center and they will match your old sump pump for half what Lowes, HD or other big box stores will sell it to you for. It costs about $75-150 for an electrician to wire it you are still lost.
I’m definitely not “lost”. But I am very curious about “oil filled poly caps” (never heard of them B4), certain failure mechanisms, and maybe dodging typical mfgr skimping.
Do you mean “Tractor Supply Company”? A search for “Tractor Service Center” turned up nothing useful - unless I need a tractor fixed.
TSC’s prices look “comparable”. House brands suspect until proven. Lowes & Home Depot often cheaper for same model of brand name pumps.
