recently,during the cold weather at night,my sons sump pump discharge line froze up between the check valve and the outside discharge outlet.i am wondering if i can drill a hole a hole above the check valve to let the water drain back into sump pit.the rise is about 8 feet. will this cause trouble? i do have a A/C D14 tractor that i use to brush hog.thank you in advance.

I don't have a check valve in my sump pump assembly - about 7 foot lift straight up. When the pump shuts off I get a backflow of about a gallon. Helps keep the pump free of trash buildup. Would be mostly lint, and soap scum, but works fine. Should be able to crack line anywhere, - worst you could get is a little backflow.

Remove the check valve, if you drill a hole, you will have a indoor sprinkler.
Have been pondering over your request, and your
A?C tractor. First ,yes drill a very small hole , about 1/8 inch dia. .Providing there is a slight slope back from the outlet. As for your tractor I would leave it in the shed , don"t think you will find to much grass that needs weedwacking this time of year. ggp

to thaw water lines i use a pail of HOT water and an old pump syphon (the plastic ones with a pump to get the syphon going), the add as long a piece of 3/8 tubing as i think i need, tubing down pipe until it stops (where the ice is) and then slowely pump the hot water into the pipe, you should be able to push the tubing into the water pipe as it thaws out... no need to take anything apart anywhere or drill any holes unless the pipe has a bend in it that the tubing can't make it round.
Seems to me that what you want to do is essentially drain out the line through a small hole in the line above the check valve. Why not just remove the check valve? It would accomplish the same thing minus the spraying water from the hole you drilled in the pipe. Just my 2cents.
The discharge line is under slight pressure whenever the pump is running. If you drill a hole in the line water will squirt out the hole, so please don't drill a vent hole inside the house.
I run 50 feet of sump pump drain line over the top of the ground in Minnesota, it never freezes in sub-zero weather.
First, make sure the outside drain line slopes continually down hill from the point where it leaves the house so the discharge water can all drain out of the line before it can freeze. Smooth walled PVC pipe drains out quicker and more completely than rippled black flexible hose.
To get the outide drain line to empty faster you can drill a small (1/8 inch diameter) hole near the highest point outside the building. Water will squirt out the hole whenever the pump runs, but once the pump stops the vent hole will let air into the top of drain line, breaking the vacuum in the line, and it will empty much faster.
If you don't want water spraying from the drilled hole add a standpipe higher than the water rises when the pump is running. That will also reduce the back pressure in the line.
Good luck.

I put a tee with a check valve above where the pipe goes out through the wall. The valve prevents overflow, but allows the pipe to drain after the pump stops. I have PVC buried a foot under ground with about a foot of drop at the discharge. Never a problem wtih freeze up.

We have a sump pump in the well that feeds the barn because it will make some water after a heavy rain. The 'well pit' is a 1500 gallon septic tank with a hole cut in the bottom for the sump pump, which sits in a bucket. We have a check in the line, and it would freeze up where the drain comes out of the top of the pit into an elbow and runoff pipe. I did drill a smalll hole in the line about a foot ablove the check so water will drain back to that point. No more frozen pipe, and the stream piddles back into the sump hole.

heat the pipe with a heat gun, the heat will transfer into the frozen area.
A hole in the pipe above the check will work, but as noted removing the check will do well. Just one pipe full of eater reenters the pit. A hole with a 1/8" copper tube attached to it pointing back into the pit will be as useful. Jim
