Why Should You Use A Garbage Disposal?

First of all, the garbage disposal will allow you to get rid of your food waste efficiently. Every time you avoid the trash can to get rid of your food waste, that is one more thing than you are doing for the environment. The drain pipes in your kitchen will be under less pressure as food scraps are liquefied.

They are long-lasting and often come with warranties in case there are issues with the manufacturing parts. While your food disposal promotes sustainability and a cleaner environment, you will be left with a clean and odorless kitchen. 

What Are The Benefits of a Garbage Disposer?

If you decide to use a garbage disposal, there are a lot of benefits that you will be able to enjoy. First of all, the garbage disposal is great for the environment. Instead of the food being thrown into the trash and filling up landfills, the garbage disposal will take care of this food waste. Breaking the food down will be beneficial for the plumbing too as when food is grinded properly, the chance of a clogged drain will become minimized.

Since the food waste will not find its way to a wastebasket or trash can, there is no chance of a bad odor ever developing since no food is rotting in your home. This will do wonders for the sanitary conditions in your home.

Features to Consider in Good Garbage Disposals

Batch Vs Continuous Feed

There are basically two types of garbage disposals to choose from, continuous feed and batch feed garbage disposals. Even though both of them are effective, continuous feed garbage disposal units are more user-friendly and preferred for use in households. The mouth on continuous feed disposal units is open and a switch will activate it. The batch feed disposals will need you to place the food inside the chamber, and then you close the stopper lid – that is when the unit will activate. This is why batch feed garbage disposals are safer if you are prone to dropping things like silverware while you work over the sink and into the machine.

Horsepower

Garbage disposal units come in a a wide area of power ratings, from ⅓ HP to 1 HP or more. Typically, higher horsepower on a garbage disposal unit is accompanied by efficient grinding and better sound insulation, align with a hefty price tag. ⅓ HP garbage disposals are categorized as entry level options and may not last long when used frequently.

Their performance Is not reliable too as harder food scraps and bones are likely to clog the drain pipes. ½ HP and ¾ HP food waste disposal models are ideal for a typical household while 1 HP is ideal for daily use. These high-powered models often grind the waste in multiple stages to liquify chicken bones, celery, corn cobs, coffee grounds etc. 1 HP or higher horsepower ratings are usually found on high-end models where unique features like MultiGrind technology  auto-reverse grind system or the Jam Sensor Circuit are used.

Noise Level

Garbage disposals are closely associated with noisy operation. However, manufacturers today use advanced sound insulation on their products so that their noise levels are significantly reduced. This is why the best garbage disposals have sound insulation and features that facilitate noise reduction, such as the noise-reducing sink baffle used by continuous feed food grinders.

The motor and the stainless steel blades will  contribute to noise emerging from the grinder chamber too. Induction motors run at lower speed and make a humming noise while it’s counterpart is extremely loud.

Mounting 

Many garbage disposals come with a “quick mount”  bracket. This bracket will need to be installed at the bottom of your kitchen sink by a simple twisting motion. A replacement unit can be placed on the same bracket too. Additionally, plugging the unit into a power outlet is much more convenient than hardwiring the component.

Chamber Size

A typical disposal unit can have a height of 18 inches. Manufacturers also recommend leaving at least 4″ to 5″ of space beneath the unit. Tall garbage disposal will not fit under farmhouse sinks. In this case, the best way to go would be to settle for a smaller sized disposal machine.

Component Materials

The grind chambers and components in a garbage disposal unit use either plastic galvanized steel, or stainless steel. The grind chamber favors thermoplastic polymer as it is resistant to rusting and corrosion. To ensure that the disposer has a long service life, stainless steel is used as it offers superior resistance to corrosion. Galvanized steel can offer the same, but it is susceptible to corrosion or rushing over time. On the other hand, higher-end models come with.

There is a sink baffle that acts to reduce noise from the machine and also prevents water from splashing upwards, keeping you dry.

Motor

This InSinkErator disposal unit uses a 1 HP motor, which has Dura-Drive technology for durability. MultiGrind Plus technology ensures 3 stages of grinding inside the large chamber. The motor works in sync with the durable alloy stainless steel materials so that food waste that are rather difficult to deal with – such as chicken bones and potato skins can be dealt with easily.

Performance

If any food that has gone into the sink and jams the stainless steel chamber here, torque is increased by a Jam-Sensor® Circuit. This will clear up the clog and the food waste that will flow through to the septic tank or sewage system will appear liquefied.

The grind system also uses Auto-Reverse technology to reverse the shredder plate’s direction to get rid of any jams. The need to use a wrench to manually address this issue is irrelevant with the Evolution Excel. This reverse movement is also seen when the wall-switch is used to turn the disposal on.

What Important Factors Should You Consider When Buying Garbage Disposal?

Type

Garbage disposals come in two feed types: batch feed and continuous feed.

Batch feed garbage disposals are activated by means of a special stopper. This largely minimizes the risk of objects accidentally going down your kitchen garbage disposal. Batch feed units will take care of the food at once while taking them inside in batches. If you cannot provide access to a power outlet in near proximity to your sink, batch feed is the way to go. 

Meanwhile, we also have continuous feed disposals that will work as long as the unit has access to power. Usually, they can be activated by: 1. Wall switch; 2. Power outlet under the countertop; 3. Sink-top switch. This versatility shows why continuous feed machines are more preferred for households.

Horsepower

The motors on garbage disposal have horsepower ratings from 1/3 HP to 1 HP or even higher.  Remember that these power ratings are key to performance and durability. 

  • 1/3 HP to 1/2 HP: Offered on basic models that are perfect for dealing with food scraps that come out every day.
  • 3/4 HP: These garbage disposal models are ideal for handling smaller bones and  food waste that is fibrous, efficiently and quietly.
  • 1 HP or Higher: These disposal units are best for heavy duty use and are integrated with technology/features for noiseless operation and powerful, fine grinding.

Noise level

The major source of noise emerging from a garbage disposal unit is caused by the grinding that takes place inside the chamber. This is why proper insulation is needed to minimize down the noise. Manufacturers have used techniques like the SoundSeal Technology, which is an advanced insulation technique. We also find that induction motors rotate at a slow rpm so that seems like your garbage disposal is humming.

While both batch and continuous feed disposals are quiet, the latter is at an advantage because many continuous batch feed disposal units come with a removable sink baffle. This rubber component is almost like a gasket that is placed over the drain so that any noise from the grinding chamber is toned down. Finally, your food disposal unit is connected to a heavy cast iron and porcelain sink, disposal noise mutes down. Stainless steel sink need a dampening material to delivery quiet performance.

Multiple Grind Stages

The disposal units that are available today will break down food in 1, 2, or 3 stages.

Single or 1 stage will grind food only once before it passes down via the drain pipes. When the food is broken down in two stages, the latter stage allows a finer grind as the tougher food wastes are liquified. 3-stage grinding offers the best grind, breaking down tough bones and fibrous wastes.

Motor Type

We can typically find two types of motors on garbage disposals, induction motors and permanent magnet motors. Induction motors are widely used because they make less noise and offer a reliable and long service lifespan. On the other hand, permanent magnet motors are lightweight and operate at variable-speeds. They usually rotate at high RPM and are most effective when the grind load is small.

Material

The grinding components are involved in most of the hard work that a garbage disposal unit does. This is why they are more susceptible to wear or tear in comparison to other parts of a garbage disposal unit. The grinding chamber should be made using material of the highest quality. So that it is durable , which is why stainless steel should be used. It will offer 100 percent resistance to rusting and corrosion.

Thermoplastic polymer is preferred for the chamber too, since it is resistant to rusting and corrosion.  Steel can be used too, but there is a chance that it will undergo corrosion if salty water comes in contact with it. Galvanized steel components are available too. Although it will offer longer service compared to plastic, galvanized steel will rust and corrode.

Mounting

There are a lot of options for installing your garbage disposal unit, irrespective of whether you are replacing an old unit or installing one. It is important that you go through all the documents like the installation guide that will usually accompany the disorder unit. Quick Lock mounting design makes installation easy because the mounting bracket uses an easy turn-and-lock mechanism that will secure the garbage disposal to the kitchen sink. If the bracket has already been installed on the sink, it can be reused to fit a new garbage disposer. 

Chamber Size

If the horsepower on a garbage disposal unit is more, the motor size will be larger and thus the unit will become larger in terms of dimensions too.  Smaller 1/3 HP disposals will have a diameter that may be between 6-7 inches wide and between 9-12 inches in terms of height. More powerful units, like those with a 1 HP motor will have a maximum height of 18 inches with a 13-inch diameter. Small households that have 1-2 will do fine with a garbage disposal with smaller-capacity.

If, however, your home has more than 3 people or you are into extensive cooking, you have to go for larger-capacity garbage disposals. The only other instance when the size of the garbage disposal unit will come into play is when the space beneath the sink in your kitchen is limited.

Connection & Switch

Continuous-feed garbage disposeal units have switches that may be electrical, mounted in a wall, or air-pressure switches that have been placed over the counter.

Even though electrical switches are placed very close to where backsplashes can happen have been used extensively over time, air-pressure switches will offer safety against shocks. They work to isolate the electrical system from around the sink area. It is also easy to retrofit them as they do not involve running wires inside the walls of your kitchen. On the other hand, models that use the Batch-feed mechanism do not need a switch because they activate when a special plug is inserted and turned.

If your garbage disposal does not include a power cord, you will need to purchase one unless it is possible for you to reuse the power cord from your old disposal unit. An alternative to this would be hardwiring the unit.

Power Cord

Power cords will be included with the delivered garbage disposal, or needs to be purchased separately. This cord is essentially if you are plugging the disposal unit to a power outlet, with minimum installation time. If the disposer needs hardwiring and comes with a power cord attached, it would be wise to take look at the installation guide before proceeding.

Auto-Reverse

Some disposal manufacturers include the  auto-reverse mechanism so that the the grind table spins automatically in the reverse direction. This will help you loosen lodged food so that it cab be processed and there are no jams.

Septic Tanks

Modern homes today usually come with septic tanks. However, remember that the food waste that is liquified in your kitchen disposal unit will not be favorable for microorganisms that are found inside septic tanks. Manufacturers such as InSinkErator have designed septic disposals that are styled like cartridges. Whenever the machine is used, microorganisms are again introduced into the chamber by injection. Sometimes, odors are added so that the natural microorganisms are smiling like citrus. These cartridges will need to be replaced when they are finished.

Price

While garbage disposal can cost between $100 and $500, the models that are less expensive will come with smaller motors (in terms of horsepower) and will leave you wanting for something more always.

Some FAQs About Garbage Disposals

Q. How can you install a garbage disposal?

Ans: This is a relatively simple task that can be completed using basic tools. Whether you’re replacing your disposal unit, or installing one – you need to begin by attaching the disposal unit to the kitchen sink. The discharge pipe will need to be attached to the drain pipe. Also remember that a switch and a power outlet have to be installed if you are installing a unit for the first time.

  • Begin by disconnecting the kitchen’s electrical connection. The drain pipes have to be disconnected. Place a bucket just below the P-trap.  Any surplus putty along with the sink strainer has to be removed too.
  •  The flange needs to have plumbers putty around it before placing it. Place the disposal on the flange so that it stays in place. There has to be a towel in the sink before you do this.
  • The mounting ring, backup flange and the fiber gasket has to be stacked up under the sink. Slide them into the flange’s underside. After pulling the snap ring open, snap it into place for installation. A screwdriver will evenly tighten the screws so that the backup flange supports them firmly. Any excess putty has to be removed too.
  • If you want to use your dishwasher, the drain plug has to be disconnected for removal from the disposal’s inlet.
  • Now it’s time for the electrical connection. The plate for the wire cover has to be removed so that the electrical cord can be connected. Put the plate back on after the wires have been set back in safely.
  • The final step needs the drain connection. The discharge outlet needs the gasket. The flange along with the bolts will be attaching the discharge tube. The mounting ring has three tabs that will need an alignment for hanging the unit. Use a wrench so that the tabs have been locked on top of the ridges. After ensuring that the discharge pipe has been properly aligned, finally, the drain pipe connection will need to be completed.

After you have placed the stopper, test how the garbage disposal is operating. Make sure that water has filled up the sink. If there are no leaks, activate the disposal by turning the power on.

Q. Why would you need to reset garbage disposal and how can it be done?

Ans: If the food disposal unit in your kitchen is not running, you need to use the overload button that is red and can be found on the underside of the machine. This can arise due to: 1. The disposal unit has clogged up; 2. It has been running for a longer duration of time; 3. The unit overheats. These or any other issue will make the unit turn off on it’s own and then reset.

The process detailed below should be followed for reset.

  • The switch should be “OFF”.
  • Now you need to press the red button for reset. If it is not budging, wait ten minutes before again.
  • Before activating the disposal unit using the “ON ” switch, make sure that cold water is running from the tap. This should get the unit up and running again. 
  • If none of this works, contact the manufacturer or repairperson.

Q. How do you unclog garbage disposal?

Ans: When you find that your garbage disposal is not draining, there is probably a jam in the system. The kitchen plunger will help you “plunge” the debris.

  • For the drain to be plunged, the dishwasher drain line has a rubber part that needs to have a clamp tightened over it.
  • The plunger has to be over the sink drain and then needs to be drained with 3 to 4 inches of water. The drain that is adjacent to it should be held with a wet rag so that several minutes of vigorous plunging can be done.
