Repair/Replace low point valves?

One of the plastic low point valves on the right of the sewer hookup has sprung a leak. The valve housing has cracked and drips a steady rate of 2-4 gal/hr.

-Where can I get a replacement valve (or some equivalent)?

-The valve has a clamp attachment (a metal band) that secures it
to the PVC pipe. Do I need a special tool to connect the replacement?

Thanks!
