sump pump and oil
I had an old sump pump corroded through in the sump basin. The oil from the sump pump drained out in the sump pump basin. I removed the pump, pumped out the water, but there is still some oil left in the bottom 1/2 inch of water left in the basin that I could not pump out.
I bought a new Zoeller 98 pump and I am ready to install it. My concern is that the traces of oil in the water might cause damage to the pump.
Is that concern warranted?
