How To Choose The Best Garbage Disposal For Septic?
Chamber Size
Do you frequently pour down a lot of waste simultaneously into the chamber?
If it's a "yes", then pick a large-sized unit to ensure it won't lack space - which could lead to blockage.
Grind Capability
For a typical home, garbage disposals with the grind capability ranges from ½ HP or ¾ HP is powerful enough.
But we would recommend you to increase up to 1 HP if you're a cooking enthusiast who utilizes the disposal every day and wants it to grind harder-texture waste like bones.
The Amount Of Food Consumption In Your Home
This is one of the most important criteria you should determine before choosing any garbage disposal for your septic system. Why? - you might ask.
The key reason is it decides on the tank capacity of the unit.
A basic rule of thumb is the larger the family, the more the waste released, which means the larger the tank volume should be.
But we want to make it clear that the largest volume isn't the best for all cases because of the increasing cost and bulkiness.
If your home usually releases small quantities of food waste that you want to send through the disposal, it's sufficient to pick a small unit.
Noise Level
Many users prioritize quietness, which is the reason we include this element here. A garbage disposal that's so loud while working could make an unpleasant clean-up experience, interrupt conversations, be annoying for seniors, and even scare kids and pets.
When looking for this device, it's highly recommended considering those with vibration absorbing parts and sound-insulated chamber to minimize the operation noise as possible.
