Sump Pump Help!!!

[EcclesCatia]

Hello All,

I have a brand new home that we took over in April/2013. I live in Ontario, about an hour away from Toronto. My builder had my sump pump (which is located beside my furnance) discharging at the side of my home between my neightbours, but it was not connected to anything. Overtime, as we had no grass, a sink hole was developing in the soil. My city inspector stated that the discharge pipe must be connected to the storm drain, which was unfortunately located at the opposite side of my house. The builder's plumber came back and did that, but now when the pump turns off, most of the water returns to the sump pit. I wanted to get a check valve installed and the plumber was willing to do it, but stated that there was a risk the pipe would freeze, causing extensive damage. He stated that the original design was optimal and I should not get a check valve installed. Pictures attached for reference of the new discharge site and the old one, plus showing how long the pipe is inside. I have no idea what I should do at this point.

I'm not sure about onterrible but in BC we needed to have French drains around the foundation, if its the same there it would be an easy tie in point, second possible option if your basement is open, run the drain to the other side of the house. Third option if you want the check valve have your plumber install heat trace on the line.

It would seem that once the pipe leaves the home as long as it's downhill all the way to the storm drain, the pipe would drain. This might make it possible to use a check valve.
