"If it's yellow, let it mellow; if it's brown, flush it down"
Have you heard of this method?
Do you or anyone you know participate?
If you don't know what it means, it refers to collecting as much urine as tolerable in a toilet and waiting until someone makes a bowel movement to flush it. It conserves water usage, lowers the bill.
My toilet is currently leaking/running, so I turn the water off until I need to take a dump or I have company coming over. The maintenance people came to fix it, but it didn't work.
