Garbage Disposal Installation and Replacement.
The typical garbage disposal system is in frequent use, and it occasionally needs replacement. At Bullfrog Plumbing, we are well experienced in the repair or replacement of your garbage disposal system. Its job is to shred food scraps down to less than 2 millimeters in size so that they pass through the sewage system. Being 70% water and organic in origin this food waste is easier to process as sewage rather the solid municipal waste that would need to be trucked away and either burned or landfilled.
Food scraps comprise between 10% and 20% of the average household waste which decomposes and generates methane gas. Modern wastewater plants are effective at processing organic solids into fertilizer products (known as bio-solids), with advanced facilities also capturing methane for energy production.
There are two main types of garbage disposals. They include continuous feed and batch feed models. The continuous feed models are more common and are used by feeding in waste after being started. In contrast, batch feed models are used by placing waste inside the unit before being started. These batch feed units are then operated by placing a special cover over the opening and twisting it to allow magnets in the cover to align with magnets in the unit. Since the unit is covered during operation, it is quieter than the continuous feed models. Small slits in the cover allow water to flow through but prevent foreign objects from falling into the disposal. This design makes the batch feed models safer to operate.
Inside the disposals the mechanism works much the same way in both the continuous feed and the batch feed units. There is a grinding chamber with a rotating metal turntable onto which the food waste drops. Then there are two swiveling metal impellers mounted on top of the plate near the edges that will repeatedly shoot the waste against the grind ring. Grooves in the grind ring break down the waste until it is small enough to pass through openings in the ring. At this point the waste is small enough to be flushed down the drain.
Usually, there is a partial rubber closure on the top of the disposal unit to prevent food waste from flying back up out of the grinding chamber and it also helps lessen the noise from the grinding chamber for a quieter operation. Many high-end or commercial disposals have an additional blade attached beneath the turntable. The purpose of this blade is to chop up any stringy food waste that would otherwise bypass the grind ring and clog the pipework.
Waste disposal units may jam, but can usually be cleared either by forcing the turntable round from above or by going beneath the sink and using a wrench to turn turning the motor shaft from below. On occasion hard objects accidentally or deliberately introduced, such as metal cutlery, can damage the waste disposal unit. Still though, a more common and difficult situation arises when there are drain blockages caused by fibrous shredded waste such as artichoke leaves, or potato peelings. Whatever the situation, our plumbers can handle your garbage disposal issue throughout South Jersey.
