I used to own a carpet cleaning service and we would use the black light to locate pet urine in order to flush those spots with a neutralizer for the odors, and then use our truck mounted system to clean the carpet.

Ideally having some sort of tenant score, or at the very least having specific parameters that applicants need to meet will help flush out bad tenants.

I've had to deal with tenants flushing down all kinds of inappropriate type of stuff, which has led to serious leaks and back-ups.

Also, ask if they have heard any ghost flushing from the toilet, if they can hear any water running when everything seems to be turned off, or if any fixtures are dripping.Visual inspection in and around all plumbing fixtures and lines might be warranted.

Some people put them up and flush them out, other people leave a space either by designer by accident. but I agree with scott, pavers have a way better look feel and ambience.

Sometimes they'll install wood framing around the installed glass block window where it meets the block wall so it gives the flush appearance when the width of the masonry is wider than the window.

Not much different than sewer- but have to service every 5-10 years, and what not to flush, etc.

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.
