I live in staten island ny. my street gets flooded all the time. There are no storm sewers only a main street drain. all of the water goes there and when it floods into my basement. I have a tub,sink and toilet. I recently installed a flood gate and thank god it stops almost all of the back up but I can't flush. what can I do to push it back out to the street and it still be able to flush?

You are literally....Up Sh-ts Creek, Without A Paddle.There is no way you could afford a pump that could overcome the hydraulic pressure.Imagine if everyone could do that. The man-hole covers would blow off, and the streets would be covered with that lovely stuff.

If codes, the sewer depth and the grading around your house permit it, would it be possible to reroute your sewer in such a way that it would overflow via the nearest manhole cover rather than into your basement? You would in effect create an inverted "U".
You would have to disconnect the existing sewer where it enters the house. Then add a riser on the 'street' side of the sewer where the first inlet is above the level of the manhole. This may require a new pipe serving the upper floors that would be run at the basement ceiling, and of course you would have to pump all of your basement sewage UP to that point. Venting would probably require some engineering as well.

I was told I could install an ejector pump. Something like commercial building have. Is this true?

No.....They have them to pump greater distances to mains, not to try to force more into an overflowing main.

In my last attempt do they sell a check valve style item for tubs? my flood gate works but it's seems my tub is lower than it, so it still gets some water before the gate closes. any thoughts?

We have the same problem in Chicago. Many homes have this or something similar.

Yet that appears to be what the Xpert method (linked below) is doing - overflowing to a sump and then using a pump to discharge water back to the main.
In severe floods, manhole covers are going to be pushed off anyway. In less severe situations, the sump pump will just pump the water that would have been in your basement into your neighbors' basements. Unless, of course, they have the Xpert vault as well.
I am wondering how local codes would treat this approach.
