We tend not to think about the pipes in our home very much.

But nothing lasts forever, including plumbing pipes, and sometimes they remind us about that us in the form of leaks and water damage.

If your home has been experiencing any of these signs it might be time for repiping your home:

  • multiple leaks
  • discolored water
  • newly bad tasting water
  • visually corroded pipes & fittings
  • noises coming from pipes
  • decreased water pressure

Some of these issues can be caused by a faulty water heater or corroded plumbing pipes. Only an inspection will be able to identify the cause.

For more information see our Plumbing Repipe Specialists page.

This leaves with luxurious softened to shower and bathe with and extends the life of your pipes and appliances.

Tech located 3/4" hot water line the burst in the slab. Tech had to removed a section of the Bottom of the vanity cabinet to access the main hot water manifold. The pipe affected was rolling underground from the water heater to the back to back bathroom vanity. This pipe supplies hot water to both bathrooms. The only hot water still active is the kitchen sink. Tech is recommending doing a reroute over head instead of repairing it through the floor.

History & Facts About Ontario California

Ontario California is a city located in southwestern San Bernardino County, California, United States, 35 miles (56 km) east of downtown Los Angeles.

Ontario is the fourth largest city in the Inland Empire region of California, and the 14th largest city in the state of California. It had a population of 163,924 people according to the 2010 census.

The area now occupied by the City of Ontario was originally part of Rancho Cucamonga, a land grant given to the Garcia family by the Mexican government during the Rancho Period.

Ontario was founded in 1891 by Canadian engineers George Chaffey and his brothers William Chaffey. They named the community after their hometown of Ontario, Canada. Ontario grew rapidly due to the success of the Chaffey brothers’ irrigation system. This system brought water from the mountains to the Ontario Valley and allowed farmers to grow crops in the area.

Ontario was incorporated as a city in 1891, and in 1903 it was declared the County Seat of San Bernardino County.

The city has a total area of 38.0 square miles (98 km2), all of it land and is bordered by the cities of Rancho Cucamonga to the north and west, Chino to the southwest, Pomona to the southeast, and Fontana to the northeast. The eastern border of Ontario abuts Upland.

Ontario continued to grow throughout the 20th century, and by the 1950s it had become a major suburban community for Los Angeles.

Ontario is now one of the fastest-growing cities in California, with a diverse community, and growing Hispanic population.

Ontario is home to several colleges and universities, including California State University, San Bernardino and the University of La Verne.

Ontario is home to the Ontario International Airport, which is one of the busiest airports in the world. The airport is responsible for over 4 percent of the Inland Empire’s total employment, with over 130,000 jobs in the surrounding area.

The city is also home to the Ontario Convention Center, which is the largest convention center in the Inland Empire.

The city is served by the Metrolink San Bernardino Line and the Omnitrans bus system.

Zip codes in Ontario California are, 91761, 91762, and 91764.
