Called the plumber for the fourth time in 4 months

[Justen Ashcraft]

Sewage ejector pump went out this time.  Before it was the float getting stuck.  He told me that there were baby wipes and a lot of grease in the pump.  In total it has cost me a little over $1300 to have this problem fixed.  What should I say to the tenants?  Can I charge them for any future repairs if I know that they are causing the problems?
