I cannot get the proper slope on a sink drain due to the area where it has to go. Can I put a pump of some type on it to make sure the waste moves to the sewage drain on the other end?

You want to put a booster pump on a drain line?
I cannot get the proper slope on a sink drain due to the area where it has to go This demands a explanation. Why can't you get slope? What would you have to do to get slope? What's the slope right now? Does it have back fall? How long a drain are we talking about? This is the kitchen sink isn't it? Back to you, Tom

Drain line from the trap to the wall. That area? If this is what you mean the pipe down to the trap is too long and must be shortened. Many times you can loosen the trap and slide it up on that pipe but usually not much.

Thanks for response. The drain that leads from the sink on first floor to the basement goes into the concrete floor and across basement. Over 10 feet of the floor has been removed and the drain is stopped up like concrete. If we go any further we have to go through a brand new tile floor that cost over $5000. Plumber said only option was to go back to the sink and where it comes out from the first floor run a drain line under the first floor joists about 30 feet so that it could connect with another drain line from a bathroom on first floor. Problem is that it will be impossible to get proper slope for the 30 feet of pipe so he wants to put a pump on it to move the water to the end of the 30 feet where it is connected to the other drain. He said it would be very expensive. I searched but could not find any such pump but of course I am not a plumber so not sure what to look for. Do not want to remove new tile floor.

"and the drain is stopped up like concrete" your plumber is a quitter who doesn't own the right equipment to do the correct fix and he wants into your wallet really bad. Call 3 other plumbers for a bid to JET the drain line. Jetting not just rodding, jet would actually remove concrete but I doubt that is what you have.

I can't see a pump working. What type of switch could be used to turn the pump on and off when the sink drains?
OK, Let's rethink the problem. Is this sink,(kitchen?) on a outside wall? If so you could route the drain outside to a grease trap and from there to a drywell( see image). This is a project you could do yourself if you're handy. Your thoughts? Good luck, Tom
