How do I know if my disposal needs repair or full replacement?

Age and the nature of the problem usually answer that. A disposal under seven years old that hums but won't spin likely has a seized flywheel or a tripped reset button, both of which are repairable. Persistent leaks from the body of the unit, a motor that grinds weakly no matter what you feed it, or a unit that's more than 10 to 12 years old are signs that replacement is the better investment. Our plumbers assess the unit on-site and give you a straight answer before any work begins.

What size garbage disposal does my Olathe home need?

For most Olathe households, a 3/4-horsepower continuous-feed disposal hits the right balance of power and cost. Smaller 1/2-horsepower units handle light vegetable trimmings but struggle with fibrous foods like celery or artichoke leaves. A 1-horsepower unit is worth considering if you cook daily or have a larger household. We carry several models and can walk you through the options based on how your kitchen actually gets used.

Can you replace a disposal in an older home in Shawnee or Lenexa?

Yes. Older homes in Shawnee and Lenexa sometimes have cast-iron drain lines or kitchens wired without a dedicated outlet under the sink. Both situations come up regularly, and we carry the parts to handle them. We'll tell you upfront if the existing setup needs adjustment before the new unit goes in.

What other plumbing services does Mr. Rooter Plumbing of Johnson County provide?

Garbage disposal work is one part of a broader range of services we offer. We handle drain cleaning and HydroScrub® Jetting , sewer line repair and replacement, water heater repair and installation for gas, electric, tanked, and tankless units, repiping, gas line services, sump pump repair and replacement, water filtration and softener installation, well pump repair and replacement, fixture repair for toilets and faucets, and light commercial plumbing including grease trap installation and backflow testing.

Do you offer trenchless sewer repair in Johnson County?

Trenchless sewer repair is not a service we currently offer. Our team uses traditional sewer repair and replacement methods, which give direct access to the full line and produce reliable, long-term results in the clay and mixed-soil conditions common across Johnson County. If a camera inspection shows your sewer line needs work, we'll explain the scope and give you upfront pricing before any digging starts.

Can you install a tankless water heater in the Olathe area?

Yes. We install, replace, and maintain tankless water heaters along with gas, electric, and traditional tanked units. Tankless systems require proper gas line sizing or electrical capacity depending on fuel type, and the venting configuration matters for indoor-mounted units. Our plumbers handle all of that as part of the installation.

Do you service commercial grease traps?

Grease trap installation is available for light commercial customers in Johnson County. Ongoing grease trap maintenance and cleaning are not services we provide. If your restaurant or commercial kitchen needs a new unit installed as part of a buildout or equipment upgrade, contact us to discuss the scope.

What Garbage Disposal Installation Actually Involves in Olathe

Swapping out a disposal sounds like a DIY weekend job until you're under the sink with water on the floor and the wrong mounting ring in your hand. Disposals need to match your sink's drain configuration, pair with the right electrical supply, and seat properly against the sink flange to seal without dripping. A unit that's slightly misaligned or connected to undersized wiring will leak or trip the breaker repeatedly, and neither problem fixes itself.
After the unit is selected, the mount is set against the sink flange with a fresh seal, the electrical connection is confirmed safe, and the drain connection to the P-trap is tested under running water. The whole process takes about an hour when the sink cabinet is clear and accessible.
If your kitchen has a dishwasher, the drain hose runs into the disposal inlet. We make sure that connection is seated and clamped correctly, because a loose hose is a leak waiting to show up three weeks after installation. Older homes in parts of Olathe and Shawnee sometimes have cast-iron drain lines under the sink, which requires a different tailpiece approach than modern PVC setups. We stock the parts for both.
