Welcome to Connelly Plumbing Solutions 'Your Neighborhood Plumber' Feel free to call direct for service: 913-768-7676 Please keep in mind that this is a lead service in which we are charged $40-$200 whether you have us out or not. Please do not request service if you are not truly ready. There are a ton of plumbers out there. We would love the opportunity to win you over.

"The first time I used Connelly Plumbing, their poor workmanship flooded my basement, and then they tried to charge me for having to send someone to fix their mess. The second time I used them, they sent an inexperienced plumber who told me he had to remove my toilet to clean out a clogged drain pipe. He got his snake stuck and had to call for backup. The more experience plumber immediately found the cleanout, which made the removal of my toilet completely unnecessary, and within minutes, got the snake unstuck. They then charged my $400 for the completely unnecessary toilet removal. Ovoid this company at all cost."

Instead, we did it ourselves - took 1 hour."

FAQs for tankless water heater installation projects in Olathe, KS

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.
