Three years ago we purchased at Home Depot a Burcam Upflush Toilet System for our bathroom in our basement. The pump motor has recently burned out and was only warrantied for 2 years. We haven't been able to locate a replacement pump like the one that burned out. We asked Home Depot and they only sell this pump in their complete Upflush Systems. We just purchased a Zoeller Pump on the web and the float won't work. The stroke length on the float is 7" which is much too high for our system. We have Burcam Model Number 450475 Pump with MDI Inc. Vertical Switch Model No. SVS-5134R. How can we find a distributor for this Burcam Pump or will another pump work in this system? Any help will be appreciated. Thanks.
