Expert Backflows in Corona, CA

Backflow services protect the drinking water supply in your home or business by keeping contaminated water from flowing backward into clean lines. In Corona and across the Inland Empire, California law requires backflow prevention assemblies to be tested at least once a year by a certified tester. Your local water district tracks these assemblies and can send a notice when your test is due, but the responsibility to schedule testing falls on you as the property owner. Properties with irrigation systems, fire sprinkler connections, or commercial plumbing lines are most commonly required to have a backflow preventer installed and tested. RAM Plumbing Htg & Air is a licensed, insured, and bonded California plumbing company. We handle backflow testing, repair, and installation for homeowners and businesses throughout Corona, Eastvale, Norco, Riverside, Ontario, Fontana, Temecula, and the surrounding Inland Empire communities. If your assembly fails a test, we can repair or replace it so your property stays in compliance. Call us to schedule your backflow service.

My shower was broken and spraying water out of the handle. I got the run around and quoted really high pricing by some other plumbing companies for over a week. Called these guys and they had a tech out in no time. Ryan fixed the problem and replaced the valve in less than an hour, all the while explaining to me what the issue was and the cost for repair (which was a lot more reasonable than some of the other quotes I got). I am definitely going to be using this company again if I need any more plumbing work done.

Michael arrived timely and was extremely kind, knowledgeable and effective. He was honest in explaining that the gas company should not have turned off my gas and the furnace wasn't broken. He tested it and it was running in a matter of minutes. I regret having to spend a fee for a diagnosis that it isn't broken. ( He did give a discount) I appreciate the kindness, experience and ability to allow us to have a warm home again. I would highly recommend this company over any other for future use.

Jeff is a phenomenal plumber. He came out and worked late into the evening to fix a hot slab leak within the wall. He completed a heavy duty job with reasonable prices. Jeff is a people person and is very professional. Jeff told me he started his plumber trade by age 20 yrs. He is very knowledgeable and insightful regarding plumbing/leaking issues behind the kitchen wall. Thank you Jeff for taking care of this matter so efficiently. I will definitely call you again. Thank you Ram Plumbing and heating company staff!!!

They did a great job! We were out of town and told the hot water heater was leaking. I called Ram Plumbing in Corona and David stayed late to install a new heater. He did an outstanding job and got us up to current codes plus a a fair price.

We had an emergency issue with our home water heater. All of the sudden it started leaking to a point that we got very concerned about water damage to our house. We did a quick internet search for an emergency Corona plumber and came across RAM Plumbing Heating and Air Conditioning. These guys responded so quickly that we were impressed right up front. They detected the cause of the water heater leak almost immediately and repair was made within couple of hours. Great customer service and workmanship. They definitely deserve five stars based on our experience!
