Frequently Asked Questions (FAQs)
How much does it cost to have a plumber install a garbage disposal?
The cost can vary widely depending on your location, the complexity of the installation, and the plumber’s hourly rate. Generally, expect to pay between $100 and $300 for labor, on top of the cost of the unit itself.
Can I install a garbage disposal myself if I have no plumbing experience?
While possible, it is strongly discouraged. Without plumbing knowledge, you risk damaging your plumbing system, creating leaks, or even electrical hazards. Hiring a professional is recommended for those without experience.
Do I need a permit to install a garbage disposal?
Possibly. Many municipalities require permits for plumbing work, even for something as seemingly simple as installing a garbage disposal. Check with your local building department to be sure.
What tools do I need to install a garbage disposal myself?
Common tools include a pipe wrench, screwdriver (both flathead and Phillips), pliers, safety glasses, plumber’s putty, rags, electrical tape, and wire connectors. You might also need a basin wrench for removing the old disposal.
What size garbage disposal do I need?
The appropriate size depends on your household size and how much food waste you generate. A 1/2 horsepower disposal is often sufficient for smaller households, while larger households may benefit from a 3/4 or 1 horsepower unit.
What can’t I put down my garbage disposal?
Avoid putting grease, fats, oils, coffee grounds, pasta, rice, fibrous vegetables (like celery and asparagus), eggshells, and bones down the disposal, as they can cause clogs and damage the unit.
How do I prevent my garbage disposal from smelling bad?
To prevent odors, flush the disposal with cold water after each use. Regularly grind ice cubes, lemon or lime peels, or a mixture of baking soda and vinegar to freshen it up.
How long should a garbage disposal last?
With proper care and maintenance, a garbage disposal can last 8-15 years. Factors affecting lifespan include usage frequency, food types processed, and water quality.
What is the difference between a continuous feed and a batch feed garbage disposal?
A continuous feed disposal operates continuously as you feed food waste into it. A batch feed disposal requires a stopper to be inserted before it will operate, grinding only a batch of food at a time.
My garbage disposal is humming but not grinding. What should I do?
The motor is likely jammed. Disconnect the power supply and use tongs or pliers to remove any obstructions. Some disposals have a reset button on the bottom that you may need to press. If the problem persists, call a plumber.
What does it mean when a garbage disposal leaks?
A leak could indicate loose connections, worn seals, or a cracked disposal housing. Check all connections and tighten them if necessary. If the disposal housing is cracked, it will likely need to be replaced.
Is it better to hire a handyman or a plumber to install a garbage disposal?
While some handymen may be qualified, a licensed plumber is generally the better choice. Plumbers have specialized knowledge and experience with plumbing systems and can ensure the installation meets all applicable codes.
