We work very closely with the City of Diamond Bar to make sure that all the work we do is up to the current building code.  Most recently, we asked the city inspector this question:

Where is an acceptable location to terminate the Temperature/Pressure (T&P) line?

We received this answer: To the exterior only!

This means that all T&P lines must run to the outside of the home.

Diamond Bar gained its name from the “diamond over the bar” branding insignia that was registered in the early 1900’s for the Diamond Bar Ranch, which at the time was one of the largest cattle ranches operating in the western United States. That cattle history is gone and Diamond Bar is mostly a residential area in the eastern area of Los Angeles County. Diamond Bar was officially incorporated in 1989.

With a population just under 57,000, Diamond Bar has a median household income of $88,000, making it one of the more affluent cities in the area. Water Heaters Only, Inc. has been proudly offering water heater service including repairs and replacements to Diamond Bar for over 51 years now. Call us at 1-626-792-2853 24 hours a day, 7 days a week and let one of our water heater experts set up an appointment for us to come out and take a look at your water heater.
