Or is about using less gallons per flush, therefore saving money?

Suddenly 2 started running water and 3 rd one started making odd sounds when flushed.

Lenders watch for this activity to flush out folks who represent a property to be a primary residence rather than the traditional fix/flip investment it really is.  

Even if you are flush at the end of the year, you’ve made money based on the other factors I mentioned above.

Now, if the clogging was caused by tenants flushing things down the toilet they should not, theoretically you could charge back the resident that caused the problem. 

Other service-oriented businesses such as hotels, museums, parks and entertainment venues also added a flush of new jobs.

Day 1 you are bound by those, and hopefully have met the tenants already to understand any issues they are already having: toilet slow to flush, heat intermittently working, etc.  

So you call the utility provider and have them test the meter. 99% of the time, the meter is fine and the issue is that excess water was used.The biggest culprit is a running toilet or one that flushes constantly.

If a toilet is clogged because the tenants child threw a shoe down there (or an older female child flushed a feminine hygiene product that clogged the system) the tenant becomes responsible for this repair. 

As long as everything goes away when they flush, all is good.
