Rochester Product Line FAQ

1. Can I purchase tanks directly from Norwesco?

Currently we are not able to combine the standard Norwesco Water & Waste Management line with the Rochester septic and pump tanks.

4. What is the warranty on your tanks?

The Rochester Product Line tanks carry a three year warranty from the date of manufacture. Should a defect appear within the warranty period, Norwesco will supply a new, equivalent tank in replacement thereof.

All Norwesco tanks are embossed with a serial number that is 1/2" in height. On the Rochester below ground tank, you will find the serial number at the "outlet" end of the tank on the right side of the manway.
