With all the new health concerns caused by COVID-19 we at Professional Plumbing Inc have increased our efforts to make sure we help stop the spread of this virus. All our technicians are now wearing a new set of gloves and booties into each home. All tools are wiped down with wipes made to kill germs, not just clean them before going back into the trucks. Hand tools are periodically dipped in rubbing alcohol to further help destroy germs. These may seem like extreme measures, but we take your health and the health of all our employees seriously. Thank you for your continued business. We are not the typical plumbers, our guys are neat and clean, well groomed, respectful of you and your property. They arrive in a clean truck that is well stocked, and best of all we don't try to charge you a ridiculous amount of money to do a so-so job. Minor plumbing leaks to replacing the sewer line in you front yard. We can handle any plumbing issue you have quickly and we are affordable. We are here to help. We want your business and it shows on every job we do. We come in and quickly solve your plumbing issues, then we clean up so well that you can't really tell that we were even there, except of course, your plumbing is working the way it is supposed to. Try us once and you will wonder why you haven't used us in the past and you'll want to use us in the future. Additional phone - (949) 646-5511, (877) 755-3519.

"Fabulous! It was Saturday and I was in the middle of canning fruit with dishwasher running. Of COURSE, the sink back up. I called to request help around 10:30 a.m. and before I knew it, the works was being done. Mark was thorough and detailed; he cleaned everything up and ensured the whole line was cleared before he left. Thank you!"

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.
