I hope someone can help.
My sump pump currently drains into my laundry tub, and has worked fine for the past 5 years. However I recently replaced the 1/3hp unit with a 2/3hp unit (after the 1/3 failed), and now the pump is too powerful. In retrospect I should have stuck with 1/3hp, but it's too late to return the 2/3 one (and too expensive to simply not use it).
The issue is that the laundry tub is unable to drain fast enough to accommodate the new pump, and it will overflow pretty much each time the pump comes on.
Having the pump discharge into the backyard is not an option because the entire span of the back is a flagstone patio and main walkway (and we don't want to be sprayed with water). The pipe cannot drain to the front of the house because the entire span is a large solid concrete patio which is about 3 feet high (plus I wouldn't want the front yard to be a swimming pool). The left side of the house is too far (approx. 40 feet from the sump pit, uphill). The only other option is to drain onto the driveway (which is actually the closest to the sump pit), but I'm concerned with freezing the discharge pipe here in Canada (especially since the pump has a backfill valve, so the pipe would stay full of water most of the time); not to mention the icy driveway it would create.
Any suggestions?
