We have just purchased a Mr. Rooter franchise and need to buy a sewer cleaning machine and see snake. We have been in the plumbing trade for 20 years and decided to make the leap into the franchise world (scarey but hopefully more profitable). I think the k7500 drum machine and a 200 foot see snake with toolbox monitor would fit the bill. Any other suggestions before we make such a costly purchase? Most work will be residential but we want the ability to do commercial if the calls come in. Any advise would be appreciated!!
