What makes it so difficult and dangerous? My super is pretty strong and handy, and has watched this done a number of times. How can I help him do it safely and effectively?
I spend Between $100 and $300 each time a main line gets clogged, which happens a total of 4 to 8 times per year for all buildings combined.
I thought it would make sense to buy a $500 tool to avoid that ongoing cost and the delay in getting it cleaned out.
The K-400 says it's good for lines up to 4" -- what about it will be inadequate?
Thanks very much!
A $500 tool won't be good enough for mains. My mainline machine costs over $2000. and yes these machines have killed. They have broken hands,wrists, arms. before you put someone else in harms way make sure they know how to do it. Having watched is not the same as having been trained by someone who knows what they are doing.
100 feet 3/4 inch cable 1/2 hp motor or above. Finally get the box of attachments for the end. Most just use the cutter. Make sure its has foward and reverse. The foot control models are nice. This way you can stand back. When you hit a obstruction this is where it gets dangerous. The cable will come back at you.
If the original poster would have got a hydrojetter in there. The pipes would be wide open and stay like this longer. Hydrojetter cleans and routes. But there big money. I found a guy who has one in my town. I will only call him now for sewer line in front yard to main in road.
