Find The Water Leak

In the past few days, we Wisconsinites have experienced sub zero temperatures.
We all know that to prevent pipes from freezing, we need to keep the areas where pipes are at exposed to a heated environment and to allow water to run or trickle to help prevent freeze ups.

I live in a apartment complex where there are four duplexes, side by side units.
Pipes froze and when they thawed, they broke, leaked, and we experienced low pressure and volume in our unit last year.

This time around, everything seemed normal, good pressure and volume. Til the night before last. We are repeating the low pressure and volume again, and I suspected a broken water line somewhere in one of the apartment feed lines.

I called our apartment maintenance man, a cobbler extraordinaire, he never fixes stuff the correct way, his work in doing repairs is mediocre at best. I told him we're experiencing a pressure and volume drop. In our conversation, he stated he came over and did not find low pressure or volume in any other apartment unit. I asked if he'd found any frozen pipes or leaks in any other units. He claimed there were no leaks, but did say that apartment # 8 had ice in the toilet.
A note: apartment # 8 is now occupied by the same idiot who resided next to us last winter, where the last pipe break occurred. Last year, he went to visit or live with mommy for over a month, when he came back, the maintenance guy told him he needed to heat his apartment while being gone. Last year, according to the maint. guy, was the second occasion where occupant turned his heat down so low, pipes froze and burst when they thawed.


I have a scheduled appointment with the city's water utility today, and they will tell me if we have low pressure and low volume by testing faucets with a PSI gauge. I'll be posting the results later.

What do you think?
