Frozen Sump Pump Discharge Pipe!
Asked Feb 2, 2009, 03:30 PM
I did a search before posting this question, but I only came across bits and pieces of the info I needed.
I live in NY and my neighborhood has a high water table. I installed a sump pump last year and ran the discharge pipe out through the foundation and into the sewer by the road. There were very heavy rains and lots of melt water in February of 2008. At that time, the sump pump was cycling on and off every 3 minutes. To keep a continuous downward pitch and still empty into the roadside sewer/drywell, I had to keep the entire discharge pipe above the frost line.
The discharge pipe has frozen and I have to fix this before the water table rises again and my basement floods. Currently, the sump pit is dry but I don't want to bet on how long it will stay that way.
- There is a proper check valve installed (see picture).
- The discharge pipe is 1-1/2" PVC without any perforations.
- The discharge pipe exits the house about 3-4 inches below ground level and is about 1-1/2 feet below ground where it ends in the sewer.
- The discharge pipe is about 30 feet long.
Should I be installing some sort of secondary pipe that branches off the main pipe inside the house to deal with future blockage?
Should I be digging up my lawn and redoing the system? Perhaps a dry well below the frost line... but would the dry well be able to handle the volume of water I'm pumping?
