The plumber tried to snake it out but he couldn’t.

And that snake was not going to be allowed no matter what, the risk was too high for the other tenants.Because almost every time I say no to a specific animal, I get an ESA letter, I think that there are a lot more scams than some want to admit. 

(I bet your supply line is a metal one with sheathing that looks like snake skin or knights armor, not braided.) 

Would probably be worth renting a snake camera if the downspouts are draining into underground pipes to make sure they are not clogged or crushed.

My current tenants brought in 2 extra puppies, snakes, rats and turtles.

@Taylor L. stole my thunder a little bit.

I'm thinking of things like snaking drains, replacing toilet guts, or touch-up painting. 

Unless your town is so terribly small you're afraid someone will recognize you and steal your thunder, you'll get a lot further if you give some details.

I had it thoroughly snaked by a pro who found multiple clogs and removed them.

Which line item can be a potential bag  of snakes?
