How To Pick Out Best Garbage Disposal For Septic
Since you are not in the situation of having a plumbing system for household sanitation, there are a multitude of things to bear in mind regarding choosing best garbage disposal for septic. Your disposal must have the ability to process multiple kinds of food waste as well as doesn’t cost you a fortune for the water bill. We have listed some key factors for you:
Waste Volume Of Your Family
The more members in your family, the more waste is discharged into the disposal and the septic tank. Hence, a considerable volume of waste from food preparation and consumption in your house means that you need a larger and more powerful unit. Meanwhile, if your family consumes a decent quantity of food scraps, a smaller and compact unit would come in handy. Therefore, this is a matter of each family’s need and budget.
The size of the disposal not only depends on the amount of food consumed by your family, but it also bases on how large your septic tank is. This means that your disposal must be large enough to accommodate the dimension of the system. Specifically, bigger disposal means a higher amount of food scraps is released into the tank at one time, so small septic systems wouldn't be able to handle that effectively. Search for compact or space-optimizing products that will give you the equivalent level of processing power without having too large of a tank.
This factor may be a minor issue with many people. However, there are still users who prefer the silent operation of their disposal since they don;t want the noise from the machine startles children and pets while they are playing in the kitchen or bothering their time while preparing meals for their family. Luckily, a wide range of brilliant disposals are designed with sound-insulation for the grinding chamber and become vibration-free before they reach the countertop.
The performance of the system depends a lot on the size and speed of a motor with the purpose of controlling the waste that you dump into the tank. In fact, if a motor grinds your food at a higher speed, you will end up creating less waste compared with a unit that doesn’t work that well. It’s ideal to have at least a horsepower or 2600 rpm for household septic systems.
This is an indispensible feature since you are looking for a disposal that does good for the septic tank. Not every waste disposal unit offers that function so you need to thoroughly read the specification in order not to waste your money.
In fact, recently, most units are likely to be designed for installation with septic systems, instead of acting as a casual disposal. In this case, the product will come with a bio-pack for microorganism treatment of the waste you dispose of. This ultimately enhances your septic system in both speed and productivity.
Continuous Disposal Or Batch Feed Disposal
Though many homemakers go for the option of continuous best garbage disposal for septic instead of the batch fee type because they are more user-friendly, the truth is the batch feed models are more recommended for your septic tanks. If you are going to purchase a batch feed disposal, you should know that this model requires some assembly by sealing it before it can truly start working.
By doing so, you don’t have to run the disposal every time you dump food into the disposal under the sink, which allows you to mitigate the amount of water needed. Especially, if you have a smaller system, a batch feed disposal may be the right solution.
Capability to pulverize waste
An unit that meets the standard capabilities to grind food must have motors with the minimum of 1/3 horsepower (HP), and offers a rotation speed range of at least 2600 rotations per second (RPM). The wider Hp and rotation speed range is, the more likelihood that the waste and garbage is processed at an extra-fast speed..
The chamber dimension is also of significance:While a small unit can work well and efficiently, you still cannot put a lot of waste down at the same time, because it may get overfilled or stuck in such a small disposal.
Though this feature doesn’t significantly affect the efficiency of your best garbage disposal for septic tanks, easy installation is a plus if you are not very good at setting things up, or spend an additional amount of money for the plumbers. Complicated installation may make it difficult even with excellent plumbers. You are likely to adore a product whose installation you are able to DIY with adequate tools and detailed instruction. Don’t worry, all products we have reviewed above are pretty easy to install either you have experience in working with disposal for septic systems or not.
The standard warranty is usually 1 year with coverage of evident manufacturing flaws. You also don’t have to take it to the mechanic or pay for the repair since it regularly offers in-home warranty. During the warranty period, all expenditure is on the manufactures.
