Hello, I'm replacing (burrying) my sump pump discharge line that runs outside and dispences out in my front yard. Currently there is 1 1/4" coming out of the house. So my question is do I convert that 1 1/4" pipe coning out of the house into 3" PVC or keep it 1 1/4" or 1 1/2" ? Also I intend on having the discharge pipe eventually come back up to ground level to discharge in the yard. Is there some sort of drain cap or protection of some sort I can put on the end of the pipe once it gets to laswn level? Thanks in Advance!

I would increase the discharge to two imches and cap the raiser that you'll bring up to grade withs a vent cap,(see image). Good luck, Tom

Thanks Tom. What is that in the photo on the far left? If it is a cap for the vent how does it work? So with the vent cap in place the water ends up hitting the under side of the cap and just disperses from there? Thanks again for you answer

It's called a "vent cap". Held in place by the bolts that you see on the sides. The pump pressure will force the water up the raiser, hit the cap and disperse around the pipe. The vent cap is about the best cover I can come up with. Regards, Tom

Thanks again Tom. Do you think it is necessary to lay pea stone or some type of rock under the drain pipe for drainage? There is quite a bit of good pitch in the yard and I definantly would prefer to just dig the hole , lay the pipe and bury it back in the dirt only?

That depends upon the texture of your soil. If you have a high clay content I would consider putting out some perforated pipe over pea gravel as a disposal aid. If you have sandy soil the flow should percolate back into the ground. Good luck, Tom

It should be 2" to the highest point of discharge run. Then, once it turns into gravity drain, you can go to larger diameter pipe.

There are flush mount pop-up drains. Look at Lowe's or Home Depot. I think Lowe's.

Thanks again Tom: I just wanted to make sure I am understanding your advise. So what your suggesting is that once I get to a good pitch where gravitty takes over stop using the 2" PVC you recommended ond go with the perforated (big) pipe? That would be about a 50' run with the perforated pipe?

That sound like a good way to help disperse the outflow. Where would the perforated pipe terminate? Would you still bring it up to grade with a vent cap? Cheers, Tom

Well Tom, that was kind of what my question was for you. If I use the perferated pipe would I still need to bring it to geound level? Thanks again!

Sorry! It all depends upon how much water you have to get rid of. Small amount? Yeah! I think 50 foot of perforated pipe would disperse the flow just fine as long as your soil would accept it.
Large amount? If water builds up in the perforated pipe And you can spread it around over the top soil I would bring it up to grade and let it spill out. If that's not a optuion I would terminate the pipe at a dry well that you would dig in. The entire thing hinges on the type of soil that you have and how much volume you're asking it to disperse and the only one that can answer that is you. Regards, Tom
