What Not to Put Down the Drain: An Orange County Checklist

01

Start with one simple rule

A drain is built to move water and waste it is designed to carry. It is not a disposal route for products that can harden, tangle, swell, or collect inside a line.

That distinction is useful because many drain problems begin with small, repeat habits: washing grease from a pan, flushing a wipe, or rinsing leftover paint outdoors.

02

Kitchen: keep grease and scraps out

Cooking oil, grease, and food scraps are better collected and disposed of with regular trash according to local guidance. Even when grease looks liquid in a warm pan, it can cool and collect farther down the plumbing system.

• Wipe greasy pans with a paper towel before washing.
• Use a strainer to catch food scraps at the sink.
• Let cooking oil cool in a container instead of pouring it into the drain.

03

Bathroom: toilets are not a trash can

Toilets are intended for toilet paper and human waste. Items marketed as flushable can still cause trouble when they do not break down the same way as toilet paper.

• Place wipes, cotton products, floss, and paper towels in a lined wastebasket.
• Keep small toiletries and plastic packaging away from open drains.
• Use the toilet only for its intended purpose.

04

Outside: protect the storm-drain path

Outdoor drains and gutters can lead to the stormwater system, so it is important not to wash paint, chemicals, sediment, or yard debris toward the curb. Sweep up loose material before rinsing an area, and follow the instructions on any product you use outside.

05

Make prevention easy to repeat

A small container for cooled grease, a sink strainer, and a bathroom wastebasket make the better choice convenient. If a drain is already slow, avoid adding harsh products just to force a quick result; an evaluation can identify the next appropriate step.
