Sewer scoping for Preventative Maitenance

[Alyssa Yumi Nelson]

I am curious about how often landlords perform sewer scoping as part of preventative maitenance. I can find info/advice on scoping as part of initial due diligence but not so much as a PM effort. Although my property in Baltimore isn't exhibiting any symptoms, it hasn't been scoped in at least 5 years. It's a 100 year old home, although city records state a permit was requested for water/sewer line re-construction in 2005. Main reason I'm hesitating is because I'm getting quoted $700 to get a scope done. Any thoughts?

@Account Closedthank you for the thoughtful response. Somehow it didn't occur to me to just go ahead and get it snaked versus starting w/ a scope. 

Do not 'just get it snaked'...that will not reveal the condition of the interior of the pipe. What is it made from? Are there root incursions? A large belly filled with mud?

You always scope first and snake second.
