Perfect solution
By Slayrider (from Central NY) on 8/17/2011
I use it in a basement laundry sink since my sewage outlet is just a bit too high. Piping and hook ups are easy and the size allows it to fit under my sink. I have used these and similar products in the past but the price here is forty dollars less than my normal supplier. Will use this product again since it is just the right size for a sink.
