We are a locally owned and operated company that values honesty and integrity, and treats your home as if it were our own. Our only priority is to provide the highest level of customer service. We know that plumbing emergencies are enough of a headache without dealing with an ornery customer service rep or repairman. We offer a warm voice, a courteous call, and a convenient process. We make your emergency a priority for us, scheduling service as quickly as possible to resolve your problem. Our plumbers are the same way—they treat your home with respect and consideration. We wipe our feet on our own mats, we wear shoe covers before entering your home, and we’ll offer you a fair assessment of your plumbing situation and how much it will cost to handle it. Our prices are flat-rate and upfront, so you don’t have to worry about inflating prices as the job goes on.

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."

"Gus and crew to the rescue! The 700-foot-long, 50-year-old galvanized steel water supply pipe from our water main burst. The main is about 1/10 mile downhill from the hours. Rather than tear up our drive we decided to trench the new PVC pipe through a wildland slope up the hill to the house. They accomplished the beastly task in less than a week, and for a reasonable fee. Highest recommendation for skill, value, and can-do attitude."

FAQs for tankless water heater installation projects in Lake Elsinore, 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.
