Overland Plumbing is your local plumbing installation and repair company. We specialize in residential plumbing services for both new and old homes. We look forward to helping you. Call us today.

"We were very happy with Patrick from Overland Plumbing! He was both knowledgeable and professional and completed our valve replacement in less time than I expected. This meant the water didn’t have to be off for hours on end, which was great! Our house is about 90 years old and I suspect this valve hadn’t been replaced in years. Someone came onto the property and managed to break it, causing problems with the water pressure. Replacing it required soldering. It’s great to have our water pressure back to normal. Thank you, Patrick! "

"Do NOT Work With ServiceChampion Unprofessional, Unreliable, Unresponsive I deeply regret choosing ServiceChampion for my HVAC installation. It has been a nightmare from start to finish. They installed a malfunctioning AC unit in October, and despite MONTHS of trying to resolve the issue, it still doesnt work. Heres a breakdown of their failures: Incompetent Installation: The system has been plagued with problems since day one thermostat malfunctions, the heat pump failing, and constant disconnections. Poor Communication: Ive made countless phone calls and emails, often receiving empty responses or no reply at all. The communication has been fragmented and disorganized. Unclear Solutions: Even when they identify a potential issue, they take forever to provide a solution. Technicians seem unsure, and Ive been given conflicting information. Lack of Accountability: Despite promises of a 100% satisfaction guarantee, theyve wasted my time, money, and caused immense stress especially with a new baby in the house. ServiceChampions negligence and lack of professionalism are appalling. They do not value their customers or stand behind their work. If you need reliable HVAC services, look elsewhere. I urge you to avoid ServiceChampion at all costs."

FAQs for tankless water heater installation projects in Signal Hill, 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.
