There were some issues and for crews working overnight on a 16-inch main water valve leak, near Swan and 19th.
It has been leaking for the past few weeks and Tucson Water shut down water service to make repairs Thursday night and Friday morning.
However, crews discovered additional pipes or valves in the area have minor leaks preventing any work from being done overnight.
Water was shut off to the neighborhood at 9 p.m. last night. About 1,000 residents were without water for a short time, many of them had water back on at 10 p.m. But work continued until about 4 a.m., with 100 to 200 homes without water while those final fixes went into place.
Tucson Water now says it will have to shut off water service again for an overnight work session within the next few weeks. Officials estimate a maximum of 160 homes will be affected during that work.
Tucson Water says it will notify potentially affected customers soon, but no work date has been set.
