Frequently Asked Questions

How much does it cost to fix a garbage disposal that's leaking?
The part costs about $8. If you do it yourself, that's your total cost. A professional service call would add $100-200 in labor, bringing the total to $158.
How long does this garbage disposal repair take?
This repair is rated "medium" and typically takes 30-45 minutes. The most time-consuming part is usually accessing the component, not the actual swap.
What if this isn't the problem?
Our diagnosis is 55% likely based on the symptom you described. If replacing this part doesn't fix it, the next most common cause for "water dripping from the disposal unit or connections" would be related to the wiring harness or control board. In that case, consider calling a professional.
Should I just replace my garbage disposal instead?
A new garbage disposal costs $100-300. If yours is well under 8-15 years old, a $8 repair is far more cost-effective. If it's near end-of-life and has had multiple issues, replacement starts making more sense.
