TOTO Toilets and InSinkErator Disposals in Waukee
This page covers two different brands that often show up in the same house. TOTO is a Japanese maker known for efficient toilets with strong flush designs. InSinkErator is a leading maker of garbage disposals that mount under the kitchen sink. One lives in the bathroom and the other in the kitchen, but both work with water and drains, so they are in our wheelhouse.
We are an independent plumber. We are not affiliated with TOTO or InSinkErator, and we do not speak for either brand. We install and repair these products for homeowners in Waukee and nearby towns. For questions, call +1 (515) 585-4137.
TOTO toilets are known for powerful, quiet flushes that use little water. Many designs clear the bowl with a swirling, siphon-type action, and some have a glazed surface that helps keep the bowl cleaner. Because the flush valve and bowl are built to work together, it matters that parts are matched and that the toilet is set correctly.
A disposal is a small motor in a canister under the sink. It spins a plate with lugs that push food waste against a grind ring. Cold water carries the small bits through the drain. It is a handy tool, but it has limits, and most problems come from using it the wrong way or from a clogged line past it.
Common TOTO and InSinkErator Problems We Fix
- A disposal that hums but does not spin.
- A disposal that is jammed, or will not turn on at all.
- Leaks under the sink from the unit or the drain line.
- Bad smells from the disposal or the sink.
- A worn flush valve or flapper on a toilet.
- A weak flush, or a toilet that clogs often.
Disposal Jams and Humming
If a disposal hums and nothing moves, something is stuck. Common culprits are fruit pits, bones, and bits of metal or glass. Never put your hand in the unit. First, turn off the power at the switch and the breaker. Many disposals have a hex socket in the bottom where a wrench can turn the plate by hand to free the jam. There is also a red reset button on the underside that pops when the motor overheats.
If those steps do not help, the motor may be burned out or the unit may be clogged downstream. We open it, clear the jam, test the motor, and tell you if it is worth fixing. A disposal that is many years old and has seized more than once is usually better replaced.
Leaks and Smells Under the Sink
There are three common leak spots. The first is the top flange where the disposal meets the sink, which uses putty or a gasket. The second is the dishwasher inlet, where a hose clamp can loosen. The third is the drain pipe on the side. We run water and look carefully, since a leak that looks like it comes from the unit may come from a nearby joint. Fixing a loose clamp is easy. A cracked housing means replacement.
Smells come from food that sticks to the walls of the chamber and the rubber splash guard. Ice cubes and a bit of citrus help a little. A deep clean or a clear drain helps more. If the odor stays, the drain line may have a clog or grease build-up. Our drain cleaning and hydro jetting can clear a stubborn line, and our article on hydro jetting versus drain snaking explains the choice.
Choosing the Right Model

For a disposal, think about horsepower. A smaller motor works for a couple who cooks lightly. A larger motor handles tougher scraps and bigger households. More power often means a quieter, smoother unit too, because the motor is not straining. Also look at the feed type. A continuous feed disposal runs while the switch is on. A batch feed model runs when you place a stopper in the drain.
Check the space under your sink. A large disposal can crowd the pipes and leave little room for storage or a water filter. Measure the depth and height. If you have a double sink or a dishwasher, the layout affects the connection points. We check before you buy so it fits.
For a toilet, check the rough-in size, the bowl shape, and the flush volume. The rough-in is the distance from the wall to the center of the drain. If it is wrong, the toilet will not fit well. Round bowls suit small rooms, and elongated bowls are more comfortable. Height matters for tall people and older adults.
Pay attention to the drain too. A great toilet cannot work well on a partly blocked line. If you have slow drains in other rooms, mention it. A good flush needs a clear path out of the house.
How We Install and Repair
For a disposal install, we shut off the power, remove the old unit, and clean the sink flange. We mount the new one, connect the drain and the dishwasher hose, wire it to the switch or a cord, and test for leaks and noise. For a toilet, we remove the old one, check the flange, set a new seal, and secure the bowl. Then we attach the tank, hook up the supply, and test several flushes.
We keep the work clean. We lay down drop cloths, wipe up spills, and haul away old parts if you like. You get a clear price before we begin. If we find something else wrong, such as a soft floor or a damaged flange, we show you and let you decide. For more toilet help, see toilet repair and installation, or compare with Kohler and American Standard.
Signs Worth Acting On
- A humming sound from the disposal, but no grinding.
- Smells from the sink that do not go away.
- A leak or damp spot under the disposal.
- A weak flush or a bowl that fills slowly.
- A toilet that runs after you flush.
Do not ignore a wet cabinet. Water that sits under a sink can rot wood and grow mold. If the drain line is also slow, the problem may be bigger than the disposal. Learn about sewer line warning signs if multiple drains are acting up.
Care Tips for Disposals and Toilets
Run cold water while a disposal runs and for about fifteen seconds after. Cold water keeps grease firm so it can be chopped and washed away. Hot water melts grease, and it may coat the pipe farther down and harden. Grind small amounts at a time.
Some items do not belong in a disposal. Avoid grease, coffee grounds in large amounts, pasta and rice that swell, potato peels, fibrous items like celery and corn husks, and bones. Eggshells and fruit pits are also poor choices. When in doubt, put it in the trash or compost.
For a toilet, clean the rim jets with a small brush if the bowl does not rinse well. Mineral deposits can block the little holes, which weakens the flush. Check the flush valve and flapper for wear. Do not use drop-in cleaners in the tank, since they can damage rubber parts. Only flush toilet paper and waste.
Hard water is a factor in Iowa. Scale can clog rim holes and harden seals. A softener or an occasional vinegar soak helps. Most important, keep drains clear with good habits so you avoid backups.
Repair or Replace?
Repair a disposal when the problem is a simple jam, a loose clamp, or a bad gasket. Replace it when the motor is dead, the housing leaks, or it jams all the time. For a toilet, repair when the porcelain is sound and the flush parts are worn. Replace if it is cracked, if it clogs constantly, or if it wastes much more water than a modern model.
Price depends on the model, the work, and what is under the sink or around the toilet. A simple part costs less than a new unit. We give a clear price after we see the problem.
Look at your paperwork. Both brands may offer warranty coverage on their products, and the terms differ. Disposals often come with a warranty that may cover parts or the whole unit for a period. Keep your receipts. If you need help reading them, we can look at your product and tell you what we see.

Questions We Hear Most
Do you service TOTO / InSinkErator?
Yes. We repair and install TOTO / InSinkErator products and can advise on a good model for your home. We are independent, so we do not favor any one maker.
Why does my disposal hum but not spin?
Something is jammed in the grinder. Turn off the power and try to free it with a hex wrench from underneath. If it still will not spin, call us.
What should I never put in a disposal?
Grease, bones, fibrous scraps, and starchy foods that swell can cause clogs and jams. Small food scraps with cold water are best.
How do I choose the right toilet size?
Measure the rough-in from the wall to the drain center. Then pick a bowl shape and height that fits you. We can measure for you.
Can a disposal cause a backup?
It can contribute if grease or waste builds up in the line. Good habits and a clear drain prevent most trouble.
