If the disposal is hit hard enough, it can actually move and shift so that it no longer sits right. The pipes can be moved; the seals can be pressed in an awkward position; or the retaining bolts can loosen. Make sure nothing has been knocked out of place. Then, check to see where the water is coming from and tighten up the bolts. If this does not fix the leak, then you will need to replace the putty or the sealing ring.
This may result in higher costs for energy needed to supply oxygen in secondary operations. However, if the waste water treatment is finely controlled, the organic carbon in the food may help to keep the bacterial decomposition running, as carbon may be deficient in that process. This increased carbon serves as an inexpensive and continuous source of carbon necessary for biologic nutrient removal.
The mounting bracket for your new garbage disposer assembles by inserting the fiber gasket, back-up flange and mounting ring over the sink flange, in that order. Be sure to hold these three pieces in place while you insert the snap ring over the flange. It’s called a snap ring because you’ll hear it snap in place. Then firmly tighten the three mounting screws against the backup flange, being careful to tighten them evenly.
Another common cause for a leaking garbage disposal is the disposal flange. A leak at the very most upper area of the garbage disposal could be the garbage disposal flange which goes through the sink. A garbage disposal flange should be sealed with Plumber’s putty and then tightened from underneath the sink. If this is not tight enough or if it has managed to come loose (which can happen) then the garbage disposal will have to be taken down so the flange can be resealed and then the garbage disposal can be rehung.
