Tenant troubles, plumbing

[Wilson Lee]

How do you as a landlord enforce your lease where a tenant is a fault for repairs and still leasing the rental?

My tenant has reported a clogged bathroom slink drain today.   We had all the drains and sewage lines cleaned 4 months ago at the tenant request at the time of move in (5 months ago) when she complained of slow drainage.   Just last month maintenance crews where on site to fix a different issue when they pulled a toy out of the bathroom sink drain.  

Our lease stats the tenant will pay for plumbing maintenance for which they are at fault.  It list out a number of items not to put down the drains.  And stats that cleaning the drains regularly is apart of the tenants responsibility from maintaining a clean and sanitary environment.   Adding this clause seem like the right thing to do when we made the lease.  But now I am at a loss as to how to enforce it.  How should we handle it? 

Option 1,  They call the plumber.

Having the tenant handle normal maintenance seems the right course of action.   I avoid having the collect payment from them. They pay for the service directly.   But I lose control of who is doing the maintenance.

Option 2, I call the plumber and then collect from my tenant.

I can choose my plumber to help control cost and quality of work. I will have to collect from the tenant. 

This tenant has paid rent on time every month except this month.  She called on the 28th of last month to say she was short on rent.  claiming medical bills for her child (single mom).  I told her I still have to send out a  legal notices and charge a late fee.

She probably can't pay for the maintenance in her current financial condition.
