Hi all -
A few weeks ago, Chicago got hit with a very bad rainstorm that apparently overflowed the sewer system. My understanding is that the city didn't want to put sewer water in Lake Michigan so they closed the sewer line for a few hours that day forcing water to flow backwards. The few sewer guys I spoke to said the water came up through a drain due to this causing some minor flooding in my finished basement.
To avoid this in the future, I've heard a backflow valve is needed where sewage can flow away from the house but sewer water cannot flow back in. I am deciding between two companies where one wants to install a pit in my front yard with a backflow valve, ejector pump, and cleanout. Whereas another company suggested a backflow valve in my basement...but I do not think this would require the ejector pump. It would require them to pull up the carpet and put a hole in the concrete but they said it is an easy fix.
Any opinions on which way I should go? I like the price of doing it in the basement but my gut is telling me that doing it in the front lawn would provide me more protection.

WE used to use a specific system with the backwater valve and pumps in the basement where it can be easily serviced. A backwater valve by itself is ONLY as safe as the integrity of the valve. In many cases it slows down the flooding with the hope that the conditions will change before damage occurs,but does not stop it

the protection you get will be the same where ever the valve is located (inside or out)
the big difference will be in the maintenence you must periodically perform.
make a mess inside or make a mess outside. you decide..

Look up the "J.R. Smith Flood-Gate" it is an excellent product and requires no pump or electricity. I've used a bunch of them in flood prone areas.

The sewer check valve is usually placed right before the drain line meets your house.That way you know
it won`t back up in your house.
