the 1/2 inch sewer machine we own, works great on 2 inch lines, but too small to do 4 inch sewer pipe, almost every week we have to rent a 1 inch eel at $50 each time, and it still too small... so here is our very own generic version of the Ridgid K1500 with C11 sectional 1 1/4 inch drain lines...
plan is to run thru all sewers lines in all 22 buildings next few weeks.
<-- made by SDT tools, cost $1200 with 120 ft of cables, Ridgid brand costs $3200.
