The pipe attached to the basement drain of my 1971-built home is partially clogged. (If I run a hose for about 10 minutes, the water starts to back up.) I believe that the drainage pipe needs to be snaked, but I am afraid that if someone does it improperly, matters will get worse rather than better. (I suspect that a clogged pipe can be easily broken). So before I hire someone to do this, I would like to know what to avoid when the pipe is snaked and how to find a competent person who will charge me a fair rate. I should add that there is a silver maple in the front yard where the pipe drains, and I understand that those types of maples attack pipes vigorously. Any help would be appreciated.
Thanks,
JD
