"When I needed to get a water heater replaced before a weekend after calling it on a Wednesday afternoon, they did it. Every other plumber called could barely send someone to give a quote! It can be hard to find a service company in San Francisco that behaves like they want your business so I was truly grateful. And while the job cost a lot more than I expected, they were able to help with the price because I was in a tight spot financially. Also, when I had an issue that I discovered later on with hot water not getting to the hydronic central heating, Adam came back to bleed the line when I was out of town! That's excellent customer service right there! They have a great team and they run a tight ship!"

"Camilo and Luis are fantastic plumbers. I manage several vintage apartment properties and always use Camilo and Luis at Pinnacle Plumbing for our routine jobs such as faucet repair and replacements, clogged bathroom/kitchen drains, water heater and gas wall heater replacement. One of the biggest jobs that we had to do was a complete sewer pipe replacement underground of our large vintage Victorian building. This involved excavating through the foundation and under the sidewalks to repair and replace sewer pipes that connect to the City sewage laterals. Luis and Camilo did a wonderful job of not only making the replacements and repairs, but we’re very empathetic to not disturb the tenants, with a focus on safety and good customer experience. They coordinated the entire large project from getting the permits to supervising the other subcontractors who had to excavate through concrete and also replace the concrete upon the jobs conclusion. You’ll be in good hands with Pinnacle! 👍🏼"

"Vincent and his assistant Sergei took on a difficult job of installing a stove top and a downdraft fan that posed some challenges of fitting into an existing counter space. An installer sent by the dealer failed at this task but they were careful and creative in finding solutions. We appreciated the attention to detail and their hard work - and the result was fabulous. Not least, the price was reasonable and both of them were easy and pleasant to work with. No hesitation in recommending their services."

Tankless water heater installations FAQs
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.
