Thanksgiving meals, family visits and busy winter weekends are great until the kitchen
sink quits draining. Around Oakdale and Modesto, we hear the same question from 
homeowners: “I thought the disposal could handle it. What happened?”

A garbage disposal can break up some food scraps, but it doesn’t make grease, wipes
or fibrous food disappear. Those materials still have to travel through the drain
line. Here’s how to make the holiday season easier on your plumbing.

## Grease and cooking oil belong in the trash, not the sink

Hot grease can look harmless while it’s liquid. As it cools, it can stick to the
inside of pipes and collect other debris. Running hot water after pouring grease
down the drain isn’t a reliable fix. Let it cool safely in a suitable container 
and dispose of it according to local waste guidance.

Butter, meat drippings and oily sauces can contribute to the same buildup. A little
bit over time adds up.

## Foods that cause trouble in disposals

 * **Potato peels and starchy scraps:** They can form a paste and build up in the
   drain.
 * **Celery strings, corn husks and other fibrous scraps:** Fibers can wrap around
   the disposal components.
 * **Coffee grounds and large amounts of rice or pasta:** These can collect instead
   of washing away.
 * **Bones and large food scraps:** They aren’t meant to be pushed through household
   drain lines.

The simplest habit is to scrape plates into the trash or compost before rinsing 
them. Use the disposal only for small amounts of appropriate scraps, following its
manufacturer’s instructions.

## What about the bathroom?

Toilets should not be used for wipes, paper towels, cotton swabs, dental floss or
hygiene products. Even wipes advertised as “flushable” can contribute to clogs in
pipes and sewer equipment. Toilet paper and human waste are the safe basics.

California’s State Water Resources Control Board has highlighted how improperly 
flushed wipes cause problems in wastewater systems. The trouble doesn’t stop at 
your property line.

## Should you pour vinegar, salt or strong cleaner down the drain?

You’ve probably seen online tricks involving salt, vinegar, baking soda or chemical
drain cleaners. Some may temporarily change odors or light residue, but they do 
not reliably clear heavy grease deposits, roots or damaged drain lines. Chemical
products may also create hazards for anyone working on the drain afterward.

Never mix drain-cleaning chemicals. If a product has already been poured into a 
blocked line, tell the plumber before work starts.

## When a slow drain needs professional attention

One slow sink may be a localized clog. Several drains slowing down together, a gurgling
toilet, sewage odors or water backing up in a shower can point to a larger line 
issue. Repeated clogs are a sign to stop treating the symptom and look for the cause.

Martin Plumbing can discuss the appropriate next step, from diagnosing a clog to
[hydro jetting and drain cleaning](https://rmartinplumbing.com/hydro-jetting/) when
conditions call for it. Hydro jetting isn’t necessary for every blockage; the pipe’s
condition and the type of obstruction matter.

## A backed-up drain before company arrives?

Skip the guessing. Describe the symptoms and let Martin Plumbing help you decide
what the line needs.
