"Man. What can I say? I am always cautious of any service but boy was I happy with Leon Plumbing. My tankless heater was leaking on a Sunday. A small leak that a bucket could handle. I called 3 places recommended by Rinnai and out of those 3 only Leon?s picked up. I told him it was not an emergency and if he could come asap. He scheduled me for Monday at noon. Omar came and boy was he a pro. Within 5 minutes he knew the issue. I could have been ripped off for the fix but their prices were extremely fair. I saved their number as a permanent contact for future service and repairs. I won?t even bother with other quotes. Once you trust you trust and I trust Leon?s Plumbing."

"These guys are the best. I had a hot water heater go out at 10PM at night. They responded to me within 10 minutes and said someone would be out in the morning between 9-10am. After trying multiple times to relight it we concluded a new hot water heater was needed. I didn't know the age of it but after some searching it was 9 years old...probably had 2-3 years left. Chris was great. He jumped in the car and went to Home Depot for a new one and was back within an hour. We haggled over the price and they graciously gave me a senior citizen discount and the price was fair. Another couple of hours and I had hot water!!! Took away my old 40 gal heater and the new box for the new one. He showed me how to light it (I knew but there's one step I didn't know....hold the button for 45 or more seconds...good to know). Everyone I've ever had at Overland Plumbing (Chris is excellent as well as Erick and Patrick). These guys are nice,friendly,quick,and give a fair price. Great company...highly recom"

FAQs for tankless water heater installation projects in Altadena, CA
Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.
Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.
Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
