Unknown tenant causing plumbing issues

[Aaron W.]

In one of our fourplexes, we a tenant (or tenants) who are flushing wipes, paper towels, and other unknown objects down the toilet which is causing plumbing issues. Our property manager has called the plumber out to the complex multiple times this past month which is costing us a little over $300 each trip. The property manager and plumber have been unable to identify which tenant (or tenants) are doing this so they advised all of them about this issue and to not flush anything other than toilet paper down the toilet. 

If this issues continues, what have you done to try to mitigate this issue?  One thought it to charge all the tenants for the plumbing charges.

What solutions has your PM company provided?  They should help provide something.  You need to check your state laws, you may not be able to just blanket bill all the tenants.  I would definitely start with documented communication about what can and can't be flushed down the toilet.  I would want to know that all of the tenants have received the notice as well.  That would be step 1.
