How can I tell if the clog is deep?

Why do plumbers say not to use drain cleaner?

Damage to Pipes: Chemical drain cleaners work by creating a heat reaction that dissolves the clog. Unfortunately, this heat can also warp or damage plastic pipes and can corrode older, metal pipes. Over time, repeated use of these cleaners can lead to leaks and other serious plumbing issues.

What do professional plumbers use to unclog drains?

Professional plumbers use mechanical tools like drain snakes (augers) for basic clogs, powerful hydro-jetting for tough buildup, and specialized equipment like camera inspections to diagnose issues, often avoiding harsh chemicals for safer, more effective, long-term solutions. They select tools based on clog severity, from small clogs in sink drains to tree roots in main lines, prioritizing methods that clear the pipe thoroughly. 

Which is better, Drano or Liquid Plumr?

Neither Drano nor Liquid-Plumr is definitively "better"; they are similar chemical cleaners, but plumbers generally advise against both due to potential pipe damage, especially with frequent use or for fully blocked drains, recommending manual methods like a plunger or drain snake first for safer, effective clog removal. Both work by creating heat to dissolve organic matter, but can corrode PVC/metal pipes and are harsh if they splash. Liquid-Plumr uses hydrogen peroxide for foaming, while Drano controls foaming; however, both may not fully clear tough clogs and can create hazards for plumbers.

What happens if I don't rinse out Drano?

Forgetting to rinse Drano allows its harsh, corrosive chemicals to sit in pipes, potentially causing pipe damage (corrosion, leaks, weakened joints, especially PVC), creating toxic fumes that irritate lungs and eyes, and damaging fixtures, leading to costly repairs and safety hazards. It's crucial to always flush thoroughly with plenty of water after the recommended time (usually 15-30 mins) to dilute and wash away the chemicals and prevent these issues.

Follow the product's instructions, pouring the hot water slowly down the drain after the recommended time, and repeat if necessary for tough clogs, but never let Drano sit for too long (over an hour) as it can harm pipes. 

What dissolves hair in a clogged drain?

Does Dawn dish soap unclog drains?

Yes, Dawn dish soap can help unclog minor kitchen drain blockages, especially those caused by grease and oil, by using its degreasing power with hot water to break down and flush away buildup, but it's less effective for solid clogs like hair or food, and some experts warn it can even worsen severe clogs if grease re-solidifies further down. For best results, pour soap directly into the drain, let it sit, then flush with boiling water, but for tough blockages, a plunger or drain snake is usually needed.
