Hello, just found this site and it looks like a really good one. I hope my first question isn't a dumb one, but here goes. My septic tank drains incredibly slowly, and during rain events, water actually flows INTO the tank. A royal pain for us. While looking at our fuse box for something else, I noticed that there is a circuit labeled 'septic pump'.........well, I had no idea we even had a septic pump, it is not in the tank as I have seen in there many times when getting it pumped out. I see no other evidence that might lead me to the location of the pump. My question is, where in the world would the pump be located? I have a sneaking suspicion that this maybe the reason for our issues. Assume it is clogged or otherwise not working. My thanks for any help that anyone can offer.

can't put my fingers on it....I installed Zoeller M98 and everything seemed to be working OK until the time when I was outside and saw that the water from the sump is forced backed to the connected spout coming from the gutter. I thought there is a partial blockage and only with heavy flow....since there is no back up of water during rain...only when Zoeller pumping out. the piping is 1.5 inch and there is a slight pitch so I don't get it. I tried to see if water from a garden hose would flow with no issues and indeed that didn't back up at all. here is a pic of how it looks like now, after I separated the connection between the leader and the sump pump pipe. You can see in the pic that the water from the sump pump was indeed [ATTACH]52591[/ATTACH]flowing up and to the left and would overflow where the leader goes into the elbow that then connects to the drain pipe. I have checked the first 10 feet or so of the drain pipe and see no blockage....before I dig and inspect another 10 feet - hope somebody can shed some light.
