If the drain remains slow, the clog is likely further down. To plunge it, first, use a damp rag to completely cover the sink's overflow hole. Fill the sink with a few inches of water, enough to submerge the cup of the plunger. Place the plunger over the drain to create a tight seal and then push and pull rapidly and forcefully to create pressure and dislodge the clog.

Goal: Clear clogs located further in the drain pipe

  • Covering the overflow hole is critical; otherwise, the air and water pressure from plunging will escape through it instead of pushing down on the clog.
  • Having water in the sink helps the plunger create a better seal and adds weight to help push the clog through.

FAQs

How long does this project typically take for a beginner, and what's the hardest part?

The initial steps like plunging and snaking the shower drain might take an hour or two. However, the most challenging and time-consuming part is often inspecting and clearing the plumbing vent stack on the roof, which could take half a day including setup, safety precautions, and cleanup. Patience and a systematic approach are key for a beginner.

What are the most important safety precautions I should take, especially when working on the roof or with drains?

Always wear safety glasses and heavy-duty gloves to protect yourself from drain debris and potential splashing. When accessing the plumbing vent on the roof, ensure you use a stable ladder and, if possible, have someone spot you for safety. Avoid using harsh drain chemicals, as they can be dangerous and may react adversely if you later need to snake the drain.

What's a common mistake people make when trying to fix a gurgling toilet, and how can I avoid it?

A common mistake is only focusing on clearing the toilet or shower drain and overlooking the plumbing vent stack. Even if a shower drains slowly, a gurgling toilet often indicates a negative air pressure problem caused by a blocked vent. Ensure you systematically check and clear the vent stack if initial drain clearing doesn't resolve the gurgling issue.

Do I really need all the listed tools, especially the drain auger and pipe wrench, or can I get by with just a plunger?

While a plunger is your first step, a drain auger (plumbing snake) is often essential for effectively clearing deeper clogs in the shower drain. A pipe wrench is important if you need to open the main sewer line cleanout to inspect for blockages. You'll also definitely need a sturdy ladder, flashlight, and garden hose for inspecting and clearing the vent stack on the roof.

So if at this point you wanted to plunge, you wanted to use a plunger because you had noticed that there was stuff down in the drain. It wasn't just the pop-up that had hair. I'm going to give you a couple of tips on that. Number one, if you just start plunging this, you're going to feel the sink like halfway with water. And you're going to plunge. But the thing is this is the overflow. It could be over here on the sink. It could be here. They're in different spots. But it's an overflow. And it connects to the drain pipe underneath. So if you just plunge, all the air pressure comes out here. So what you want to do is take a rag and a little wet. Make it damp and hold it over the hole with one hand. And with your other hand, then to sink hair full of water, then you could plunge away. I'm going to link right now to a video I have on plunging. You know, plunging 101, basically everything you want to know about plunging. But sink hair full of water plunge really fast and hard. But first, of course, covering the hole with one hand with a wet rag. Sink hair full of water. I'm going to let someone water down the pipe, then plunge really fast. Let someone water down, then plunge really fast. That's basically the quick primer on plunging a sink.
