The most effective drain clog prevention is controlling what goes down them. Hair, grease, food scraps, and so-called “flushable” wipes are responsible for the vast majority of household drain clogs. A few simple habits — combined with occasional professional drain cleaning — will keep your drains flowing reliably and help you avoid the expense and inconvenience of a backup at the worst possible time.

Kitchen Drains: The Grease Problem

Grease is the number one enemy of kitchen drains. Cooking oil, bacon fat, butter, and similar substances flow down the drain as a liquid but solidify as they cool, coating the inside of the drain pipe and accumulating over time. Eventually the coating builds up enough to restrict flow significantly, and whatever else goes down the drain starts getting trapped in it.

The fix is straightforward: never pour grease down the drain. Let it cool in the pan, then wipe it into the trash or pour it into a sealable container for disposal. Run cold water through the garbage disposal for 15–20 seconds after each use to flush material through the trap and into the main drain line. Avoid putting fibrous vegetables (celery, artichoke leaves), starchy foods (potato peels, pasta, rice), or coffee grounds down the disposal — all of these either wrap around the impellers or turn into a sticky paste in the pipe.

Bathroom Drains: Hair and Soap Scum

In bathrooms, hair is the primary culprit in shower and tub drains, and soap scum provides the glue that holds it all in place. The simplest prevention is a drain screen or hair catcher over every shower and tub drain. These inexpensive devices catch hair before it enters the pipe and can be cleaned out in seconds. Without one, hair accumulates in the P-trap and the first few feet of drain pipe until flow slows to a crawl.

Bathroom sink drains most commonly clog from toothpaste residue, soap buildup, and small items falling in. Keep the stopper mechanism clean — the pivot rod assembly under the sink is a common place for debris to accumulate — and avoid letting hair accumulate around the stopper.

Toilets: What Not to Flush

Toilets should only receive human waste and toilet paper — full stop. Despite what the packaging says, “flushable” wipes do not break down the way toilet paper does and are a major contributor to drain line and sewer blockages. The same applies to cotton balls, cotton swabs, dental floss, feminine hygiene products, paper towels, and anything else that isn’t toilet paper. These items may clear the toilet bowl, but they cause problems further down the line.

Whole-Home Drain Habits That Help

A few broader practices worth building into your routine:

  • Run hot water down bathroom sinks periodically to help move soap residue along
  • Check slow drains early — a slow drain is a clog in progress, not a stable situation
  • Avoid chemical drain cleaners as a regular maintenance tool; they can damage pipe interiors and rarely solve the underlying accumulation problem
  • Consider annual professional drain cleaning as a proactive measure, especially in older Denver homes where the drain lines may have accumulated years of buildup

When Prevention Isn’t Enough

Even well-maintained drains can develop issues over time, particularly in older homes where cast iron or galvanized drain pipes have roughened interior surfaces that accumulate buildup faster than smooth modern pipes. Done’s drain cleaning service uses professional equipment to clear drains completely rather than just punching a hole through a clog — which is what most chemical products and basic snaking does. For persistent or recurring clogs, a camera inspection through our sewer services can identify the root cause, whether that’s buildup, a root intrusion, or a pipe that needs repair.

If you’re dealing with a slow drain or a backup right now, contact Done — or if it’s urgent, our emergency drain cleaning service is available when things can’t wait.
