We have a rental property and the tenants called us to repair a toilet that wasn't working. We went that day and repaired it. When we were there, one of the tenants told us that the water bill was extremely high, $500+ . When we looked around the property, we saw that the water heater had been leaking from the bolt on the pipe, and had been leaking for a LONG time. We immediately fixed it that day. The tenant called us and wants to split the bill. We did not know of this leak until that day, so I would like to know who is actually responsible for that bill. In the lease, it is stated that the tenant is responsible for all utilities.
