burrying sump pump discharge pipe

[fletcher]

I am thinking of doing this. Sump does not run in winter, Twin cities location. lookout basement, current sump discharge 1.5" connected to 12' of 4" corrugated pipe on top of soil. thinking: 30 foot run 3" pvc.

what type of pvc? just burry it?

how / should I end run into a pop up? I dont have a ditch or storm sewer to go to just want standing water away from my house.

rent a trencher, 2' to 3' deep sloping downward away from foundation.

air vent outside of house for ice back flow prevention.

Thanks

I just did this a couple years ago. So far zero issues. My sump pipe is 1 1\2" PVC that comes out the house in the garage, goes along a wall (I also installed a 6' tall vent stack at the highest point, because once the. ump turned off the water in the pipe would siphon back into the pipe and partially refill the sump) and out the back wall, then turns and travels along the back of the house for about 20 feet where it meets up with the buried 4" PVC that goes about 30' out to a collection box the city installed in our yard by the curb, that is then piped to the nearby storm sewer.

I used the green 4" PVC found at menards and it was fairly easy to work with, except for gluing it together which required two people, a concrete wall, a wood block, and sledgehammer to get them together. I went with 4" myself because I also connected a couple of my downspouts to the system, and since doing so my sump pump use has gone down probably 90%. In the past springs and after heavy rains the sump would run almost constantly, it now may run once an hour if at all. Last spring thaw the sump was actually dry until we had some huge rains. If you can do it I'd highly recommend doing something similar if you have a downspout that drains into an area that doesn't drain well.

If you go with a pop up at the end make sure you put some pea gravel a couple feet down under the pop up to help it drain the water stuck inside. My neighbor ran 1 1\2" out to the street and daylights it a foot or two from the curb. Seems to work well for them, but they are on a slight hill so won't work for everybody.

I would try to terminate it without any kind of elbow or pop up and the reason is this. If you do it that way, it will pretty much guarantee that if its needed to be out in service in the winter time, it will be froze up. Is there no place to drain to daylight on your property

When I did this I had to run a 3/4 inch line the length and width of the house. I dug a trench down 20-24 inches and ran it down the hill and put in 1 or 1 1/2 inch pvc that comes in the 100 foot coil. Terminated it in a box with a open cover and then out into a french drain in the front yard. I have a check valve right about the sump and that stops the water from going back into the basket. I also had to put an air valve in the line at the highest point because the water would gurgle forever as the line drained down.

The thing does freeze up in the winter and the water from the furnace and the humidifier go into the sump. I put a line that runs into the wash tubs and it has a valve on it so I can open it up in the mid-winter when the outside setup is locked up.

My setup is probably 75 feet long inside the house and 60+ on the outside. It is entirely enclosed and so I haven't had any critters get in - at least so far.
