Do I need a new garbage disposal? This is one common question that many home owners ask whenever their garbage disposals tend to misbehave. However, not all garbage disposal issues require you to buy a new unit.
While garbage disposals are designed to last many years, the lifespan can vary depending on how it’s treated.
In this guide, I’ll give you insights on when to replace your garbage disposal including the available options.
Do I Need a New Garbage Disposal?
You actually don’t have to replace your garbage disposal every time it fails to do what it is meant for. Most of the common garbage disposal issues include grinding noise, slow draining, bad smell, humming noise, leaks among others.
While most of these issues can resolved, there’re some tell tales that your garbage disposal needs replacement.
You need to replace your garbage disposal whenever the unit displays one or more of these signs.
Slow Drain and Frequent Clogging
If your sinks suffers from frequent slow draining and clogging, then something might be wrong down there. There’re two reasons your garbage disposal is suffering from frequent clogs.
If you’re using an undersized garbage disposal, then there might be a tendency to choke the grinding chamber with excess garbage. This causes the garbage disposal to jam thus leading to frequent clogging.
Garbage disposals come with vary levels of horsepower depending on the garbage output from your household. Getting the right size ensures that garbage is grinded properly so that it won’t cause clogging down the drain. Plus it lessens likelihood of jamming.
Use the guideline below to choose the correct size of garbage disposal for your household.
- For 1-2 persons, use 1/3 or ½ HP garbage disposal
- For 3-6 persons, use ½ to ¾ HP garbage disposal
- For 5-8 persons, use ¾ to 1 HP garbage disposal
- For more than 8 persons, use 1-2 HP garbage disposal
Requires Frequent Resetting
Garbage disposals are equipped with a reset button which disconnects the electrical power in case the motor overloads. It’s placed at the bottom of the unit so that you can conveniently restore the electric power whenever it trips.
If your garbage disposal unit requires frequent resetting, it could mean that the motor is losing its power. A defective bearing also puts additional load to the motor thus causing it to trip.
Since garbage disposals come with non-serviceable motors, the only thing you can do is to replace the whole unit.
If your garbage disposal unit leak on the top, that could be a sign of a loose or damaged flange. You can easily solve such leakages or call a plumber to fix it for you. If the flange is damaged, you’ll have to replace with a compatible flange.
A leakage from the bottom, indicates a broken seal or cracked internal shell. It’s more cost-effective to replace the whole unit than repair such damages. Plus a new garbage disposal will last longer than the repaired unit.
After some time, the grinding chamber tends to accumulate grime and food debris thus causing lingering odor. However, you can minimize garbage disposal odor by regular cleaning and deodorization.
If greasy and fibrous substances stick deeper in the garbage disposal they might prove very difficult to remove. Such substances are usually associated with lingering odor no matter how much you clean and deodorize the inside of the garbage disposal. Getting a new garbage disposal could be the only option for escaping such odors.
To keep your garbage disposal free from stubborn clogs, avoid tossing greasy and fibrous garbage.
Installing a Replacement Garbage Disposal
If your garbage disposal has malfunctioned or is unable to handle your current trash output, then it’s time to install a new unit. A more powerful garbage disposal is able to handle increased garbage output and therefore prevent frequent clogs and lingering odor.
Most garbage disposals come with easy to use installation guides which can be effected without prior plumbing knowledge. If you’re not confident about your plumbing skills, you can contact the local handyman for a quick installation.
Otherwise, you can do it yourself by following this step-by-step garbage disposal installation guide.
