Factors to Consider to Choose the Right Garbage Disposal for Septic

Type

First and foremost, I always advise consumers to take their time, research thoroughly about a product and then make a decision of whether or not they want to invest in a particular option. In the case of choosing the best garbage disposal for septic, the first step is to look at the type of product which suits your needs the best. You might find a variety of garbage disposals around the market, however, all these options fall under two major categories i.e., continuous garbage disposals and batch feed.

As the name indicates, continuous garbage disposals are usually used if you produce large amounts of kitchen waste on a regular basis. They are more suited for small commercial applications and require a continuous feed. There are multiple benefits of using these models as they can lead to the management of large amounts of waste and are relatively cheaper and can be purchased at reasonable rates. However, on the downside, these models require increased water and power consumption because they work on a continuous basis.

They are also associated with an increase in the risk of accidents because they are powered on a regular basis. In contrast, the batch feed models are different and can be used for residential applications in case of low kitchen waste production. They work in batches and thus are energy friendly in nature. You also do not need to keep them switched on all the time and hence, they contribute to the reduction in accidents. However, these models are relatively expensive and do not offer a high variety in terms of design and features.

Waste Volume

The volume of the waste generated should also be taken into account to reduce the unwanted hassle and choose the correct size of the garbage disposal unit for yourself. The amount of waste generated is highly dependent on the frequency of cooking as well as the number of individuals in a family.

The higher the frequency of cooking and the greater the family size, the more waste will be generated, and therefore, in turn, you will need a larger unit to accommodate all the waste. Additionally, keeping the waste requirements into consideration will also help you ensure the efficient functioning of the disposal system and will also offer you full control over the electricity bills and other associated costs.

Grinding Power

Grinding power is another factor that is associated with the improved performance of the disposal system. It is important that you invest in a powerful disposal system with large grinding power if you are working on large amounts of waste and you generate waste frequently in large quantities.

The high grinding power and a powerful system will help you improve your overall performance and will complete the task ahead of time. Hence, making it easier for you to manage the waste and save time for other important activities. I highly suggest using a 1 hp motor for large families as it will generate enough power for you to process large quantities of waste while consuming a lot of power or energy in the process.

Warranty

You should also check for the warranty of the product as it will help you claim the replacement or repair of the model free of price in case of some manufacturing defect or technical default. The warranty can save your day in case of some accidental damage to the disposal unit and will help you achieve the utmost services regarding the replacement of the old version with the new one without paying a single penny.

A variety of products are available with a lifetime warranty and are a perfect choice to secure your product for years. You will also find options with a warranty of around 1 to 2 years, however, they are not as preferable as those with a lifetime warranty as you can claim a warranty at any time if your disposal unit is covered by a lifetime warranty.

Septic Compatibility

Besides the above-mentioned factors, you also need to check the compatibility of the septic tank. The septic tank is the specialized component of a waste disposal system that is used to break down the food waste into smaller components in order to convert it into sludge. The sludge can then be processed easily without any performance issues.

Some highly advanced models might also be available with bio pack-attached septic tanks that require various enzymes to increase the activity of microbes to break down the food easily into smaller components and then use them as sludge. You need to check the compatibility of the septic tank with the enzyme being used as well as the food waste that has been introduced into the system for treatment. Doing so will help reduce the performance errors significantly and will improve the overall performance of the garbage disposal unit to a great extent.

Size and Other Features

Another factor that is worth paying attention to is the size of the disposal system. Similar to the grinding power and waste volume, the size of the garbage disposal also depends upon the frequency of waste generation and the number of individuals in a family. If you have a large family and you generate large quantities of waste on a regular basis then it is essential to purchase a large model that can accommodate your needs with utmost accuracy and efficiency. Doing so will not only contribute to time efficiency but will also help in maintaining the performance of the system.

Besides this, you can also look into other factors such as the anti-jamming and auto-reversal abilities of the grinder. Considering these advanced features and comparing different options on the basis of these attributes will help you in making a sound decision and will also prevent you from future performance concerns. Lastly, you can also check if the model you have chosen is corrosion resistant or not as it is highly important and can affect the overall performance and average life of the best garbage disposal for septic tanks.

Frequently Asked Questions

Are garbage disposals safe for septic systems?

Yes, the garbage disposals are in fact designed to be used with the septic tanks to increase the overall efficiency of the system when managing food waste. However, you should clean it on a regular basis to prevent them from contaminating the septic tanks, especially in case of sludge formation.

How often should you pump your septic tank?

It is important to pump your septic tank on a regular basis to prevent the growth of harmful bacteria and keep the tanks clean in general. I advise pumping the tanks and carrying out a thorough cleaning activity once every three to five years for best results and to increase their average life.

What is a continuous feed garbage disposal?

A continuous feed garbage disposal is designed for processing large quantities of waste and works continuously when plugged into the switch. These disposal systems are versatile in terms of design and performance and are available at reasonable rates, however, they pose the threat of unwanted accidents because of their continuous electricity usage.
