How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 8 of 10
This project involves the complete removal of an existing garbage disposal unit and its mounting hardware from a kitchen sink. It will be replaced with a new, standard sink strainer and a complete drain pipe assembly, including a P-trap and connections for a dishwasher, if present. The process requires disconnecting power and plumbing, removing the old unit, cleaning the sink, and installing the new components, followed by a thorough leak test.

FAQs
What are the most important safety steps I need to take before starting this project?
Always disconnect power to the garbage disposal circuit at your breaker box to prevent electrical shock. Also, turn off the hot and cold water supply valves directly under your sink to prevent accidental leaks or sprays during plumbing disconnection. Wearing heavy-duty gloves is recommended to protect your hands from sharp edges or chemicals.
How long should a beginner expect this project to take, and how difficult is it really?
This project is rated "beginner" and typically takes 2-4 hours for someone new to plumbing. The main challenges are working in a confined space and ensuring watertight connections. Taking your time and following the steps carefully will lead to success, so don't rush the process.
What type of sealant should I use for the new sink strainer, and how do I apply it correctly to prevent leaks?
You should use plumber's putty for sealing the new sink strainer, which is often included in a build-up kit. Roll a rope of putty and apply it generously around the underside lip of the new sink strainer before inserting it into the sink opening. Tighten the strainer nut firmly from underneath, allowing excess putty to squeeze out, then trim it away with a putty knife for a clean, watertight seal.
I've installed everything, and I'm seeing a slow drip during the final leak test. What are the most common places for leaks and how do I fix them?
Leaks most often occur at slip-joint connections or the sink strainer seal. For slip-joints, ensure the nuts are hand-tightened first, then gently snugged with Channellock pliers, checking that the washers are correctly seated and not cross-threaded. If the strainer leaks, it might need more plumber's putty or a firmer tightening of the locking nut from underneath the sink.
