And what exactly does a sump pump do? And why don't all septic systems have them?
And why don't all septic systems have them?
a sump pump has nothing to do next to the septic system its used to pump water out of a cellar so that the underground room doesnt flood
It have nothing to do with the septic system.
A sump pump pumps hose out of the sump. (Say that three times real fast!)
Most houses next to a basement have what are call drain tiles around the foundation. The idea is that rain or melt snow goes into a pathway that leads to the sump. This is really nought more than a pit or well that is below the horizontal of the floor so that the water can be directed downhill into it.
The pump simply moves the water out of this sump, through a pipe within the wall and out into the yard. The pump can either be completely submerged surrounded by the sump or be of the pedestal type where the motor is in reality above the hole.
The bad thing roughly speaking sump pumps is that you need them most when it's raining really, really hard. But what usually happen when there's a gigantic storm? The power goes out. Oops! A big problem that makes insurance companies move about bonkers.
No connection to the septic system. Besides, I don't think you'd want sewage flowing into an clear hole in your basement where on earth it sits until it fills up enough to see on the pump. Then again, maybe you do! I hope not.
Hope this helps you have a handle on.
Answers: The one and only septic systems that have pumps are septic systems that are below the street level sewer pipes. The pump is needed to pump the sewer into the sewer pipe. The sewer systems that are above street rank sewer pipes will drain into the sewer pipes by gravity so that is why no pump is needed. When I had my System installed I be told I would not need a pump, but when they started digging they found a huge boulder under my driveway that they could not blast so my sewer system wants a pump to pump the sewer over the boulder and down into the street pipes. I had to have this pump replaced second year and it cost me $3500. So expect to replace that pump every 8 to 12 years. Not something I like, but have no choice.
