Landlord/Tenant Law Question

[Dennis Hill]

I could really use some advise from the BP Community!  I am having some difficulty with one of my tenants.  Here's the scenario - I have/had my tenant set up on biweekly automatic rent payments through her workplace payroll.  She has missed the last 2 payments.  The property is in need of a new HW Heater.  She just reported she had no hot water Friday.  I had a plumber come out to assess this issue Mon.  My question is can I delay installation of the new HW Heater until rent is paid?  I feel it's my only recourse/leverage at this point since courts will not process evictions in the state of MD as a result of Corona Virus/COVID-19 pandemic!  I'd really appreciate any advise you all are able to offer!
