Tennant's daughter slipped on puddle, liability questions?

[Cody F.]

One of our Tennant's daughters apparently just slipped on a puddle and fell according to the tenant.

This came after I sent out a notice that she owed a balance on her account. She refuted the bill and then said by the way my daughter just slipped on water in the kitchen from a leak.

Our showers are directly above the kitchen and are aging. our maintenance kept replacing washers to keep them going, but I've started to have the 4-ways replaced entirely. This apartment had the 4-way replaced but then had leaks. I've had 3 different people out to fix the 4-way, and now the leaks. It's getting better, and we thought it was solved for good last week but it started leaking a small drip when the shower is on.

Now apparently the tenant is holding this issue over my head for sending her a past due account notice.

I have the guy coming back out, and tomorrow is the soonest he can get here.

Am I in trouble here? Should I handle it differently? Or am I doing the right thing?
