Yes to all of the above... but primarily for rental property and ocasionally for the Hospital where I work. I've never needed a rooter for any place that I've lived.
All of the rentals have cast iron under the buildings which transition to buried 1920's clay tile to the street.
I firmly believe at least 80% of lateral line blockages are caused by tenants with 99.9% of in home blockages are tenant caused.
My one exception is a property built in 1955 with 400' of Orangeberg sewer line... looks like rolled tar paper. I'm working with my neighbor, we share part of the line, to use my
BX23 to run a new ABS. The estimate to do a trench-less replacement for my portion was more than I paid for my
BX23 new.
Latest case was last a blockage last Sunday. Called Mike my regular rooter guy. He pulled up two hypodermic syringes along with a wad of "Hygiene" products.
Mike is a great guy, almost one of the family... at least I see him more than I see some members of my family. He's almost 70 and starting to slow down and looking to retire out of California any day now.
I went with Spartan because he swears by them and not at them!!! The 300 is the machine he uses most for my jobs. He also has a 1065 model for big jobs.
I expect it will take at least a week before my machine arrives...
Thanks for you help.
