Water Meter Issues in multifamily

[Dan Oconnell]

Hello Bigger Pockets, 

I am writing this afternoon seeking advise. 

I made a mistake while purchasing my 2nd multi family with the water meter. Long story short the inspector and myself did a bad job of fully understanding the situation. 

Here is the current situation. I bought the home with renters in. They are fresh renters so they are just getting their first water bill. The house has a single family 4/1 and a small guest house 1/1. The issue right now is the water meter. There are 2 meters by the road but water company says the pipes were never connected to the small guest house. 

Water company also says I have to put the water in my name if there are 2 units and they are both rented out. 

With the leases already in place how do I prevent myself from paying for their water out of my pocket?

Thanks in advance for all the input.
