Sub metering a quadplex

[Adam Snow]

I am under contract on a quadplex that only has 2 water meters. The owner was just paying the water/sewer which was about $130 a month. I want to sub meter the water and sewer so that the tenants can pay for their own and increase my return. I wanted to see if anyone had any experience with this. I found a couple companies that were recommended in other forums but they only do it for bigger units. Thank you in advance for any advice!
