Is a written "frozen pipe agreement" legal in Chicago?

[Zachary Davidson]

Hi, all. First time poster here out of Chicago! My Question; is it legal for me (property owner/landlord) to create a signed agreement with future Tenants that states, when the outside temperature drops below a certain degree they must "trickle" water from all faucets to prevent bursting and frozen pipes? (property was built in 1890)

Also in the agreement I wrote, if they did not apply this "trickle" technique, the potential repair responsibility$$ would fall on them after acknowledging and signing the agreement. 

Not sure if anyone has created something like this, or let alone be legal for a tenant to sign?

Thank you, Zach.
