Far from an expert here so i thought I’d ask you experts. So come home to check it, open the hatch and the pipe that sends it to the sewer line is vibrating(thinking that’s the pump at the bottom). Nothing is pumping out and the water is at the top of the line coming from the house. My brother is a plumber and he came over to check it but didn’t have his pump to pump it out. We’re thinking the pump may be screwed? But won’t really know until tomorrow till we can pump it out. My neighbor came out and said we have grinder pumps, so that sucks......more money. What do you guys think?
