Tuesday we received calls from tenants in both sides of our duplex. The toilets were backing up into the bathtubs and would no longer flush. We called a plumber and paid $320 for them to unclog the pipes. Saturday morning we get another call that plumbing is backed up again. We paid a $450 premium for a weekend plumber who “removed heavy accumulation of feminine products from line.”One tenant is a bit older. The other is a young mom with teenage daughter. Should we charge both tenants even though we suspect the younger tenant is the one causing the issue?
