Save big money on clogged drains

I learned this one the hard way..........the main drain in my house gets clogged about once
a year......they tell me the pitch of the drain out to the street might be uphill and the sludge builds up.....anyway a call to Roto Rooter is $500 and Econo rooter is up to $450 now and I
will tell you it is robbery.....he brings a motorized snake in and runs it about 90 feet in 30 minutes clears the drain and wanders down the road to steal another $500 where do I get a license to do this? Anyway,2 better solutions........you can rent a motorized snake at the rental
place try Rentals Unlimited on Southlawn Drive in Rockville,or bit the bullet and buy a motorized snake....funny enough I looked and it will run you $500........but then you can make money off your friends and neighbors!!! Just trying to save you some money from my past mistakes!
