I'm getting set to run some 4" schedule 40 PVC underground away from the house. The question I have is I'm trying to figure out where to end the pipe. I can't go to the ditch in front of my home which would be ideal because I will be crossing over the underground electrical/phone/cable line. I have what I call a drainage creek/ditch straight out from the side of my home where the discharge pipe starts. The creek/ditch does fill up in the spring as well as during extended days of rain, but nothing up towards my yard. I'm worried if I run the pipe to that location, the end of the pipe will be covered with water when the creek/ditch area fills up. I don't have any other steep grades near the creek/ditch because of the grading already done. Should I build a make shift dry-well or are there other suggestions. If a picture is needed, just ask and I can try and produce a fairly detailed one. To run the schedule 40 it would be about 100 ft away from the home.

Are you saying that you're afraid it will back up into your basement?

[Gus_19]

I really don't think it will back up to by basement because of the pitch the pipe will have in the ground, but do you think that would be an issue?

[speedball1]

No I thought you thought it might become a issue if the end of your pipe was under water. What's the problem with discharging it into the drainage ditch. This isn't gray water that you can't discharge into a open ditch. I say dump it in the ditch. Good luck, Tom

I do plan on running it to the drainage ditch and yes it is gray water, but in the spring mainly, I think the end of the pipe will be covered by water. At least if I run it too close.

What do you mean "it's gray water"? Didn't you read my post where I said,

What's the problem with discharging it into the drainage ditch. This isn't gray water that you can't discharge into a open ditch. I say dump it in the ditch

A sump pump collects and pumps out ground water that's seeped into the basement not gray water from a tub or washer. If you're going to discharge gray water you'll need a dry well. Let me know exactly what you're planing on discharging into that ditch. Regards, tom

Sorry about that Tom. I didn't mean to say gray water. Not sure what I was thinking then. Just water from the sump pump. I.E. ground water coming into drain tile

Cool! You may have a problem if the creek raises higher then inlet ppe to the pit. But since the creek would hafta raise over 25 inches to back up into the sump I wouldn't let it concern me. Good luck, Tom

I guess the key is how you plan to attach your sump discharge to a 4" PVC. The sump has a check valve but I would not rely on that to prevent a back up. Discharge your 2" sump outside and direct it into the 4" pipe but not a hard connection. Use what's called a indirect connection and you will not get a back siphon.

ditch in front of my home which would be ideal b/c I will be crossing over the underground electrical/phone/cable line.

What's wrong with that? Bob's right, just use 1 1/2 or 2" pipe and grade it such that its only a few inches underground and go over the utility lines.

I haven't really looked into yet how I plan on connecting the sump pipe to a 4" pipe. When my plumber came over one day to look at the sump for me, he had drilled I believe a 1/8" hole at an upward 45 degree angle. If I remember correctly, it's between the check valve and pump itself. I do plan on putting some sort of cleanout just outside the house where the sump pipe and 4" link up.
