Additionally, you have to educate the tenants on what can be flushed.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

The industry is going to consolidate soon and these bad actors will be flushed out.

My lease requires tenants to pay to have sewer line maintained once a year since they flush all kinds of garbage.

Im just starting out and learning a lot with home maintenance.I try to inspect the units every now and then to make sure kitchen and bathroom ok (seals around tubs, no leaks under sink, toilet flush ok, etc), and I also ask tenants if they notice any leaks anywhere pretty often. 

Just make sure to shim it flush with the existing, and if you can get a scarf joint in there, it  will look and hold better. 

During that time, we washed laundry, ran the sinks, flushed toilets, etc.

For me low flow toilets and older plumbing were not a good mix; constant plunging and double flushing made me switch back.
