If you discover your cleanout cap is missing, it's crucial to replace it immediately. An open cleanout can allow debris like rocks, glass, or dirt to fall in and cause a serious clog. The video shows an example where a glass bottle was used as a temporary cap, which broke and clogged the line. Purchase a new, proper-fitting cap from a hardware store and screw it on securely to prevent future issues.

Goal: Replace missing cleanout cap

  • Do not use improvised caps like bottles or rocks, as they can fall in and cause a major blockage.

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 you notice that your clean out is missing, it's cap, it is very important that you go purchase one and put one on it because if you don't, this is what can happen. Jordan, why don't you tell people what we found down in that hole? Well, down in our drain. We did find some glass and Jordan, why was the glass in the drain? Well, I guess the homeowner thought that it would be a good cap cover and that bottle ended up falling down into that drain and busting and that ended up causing their lines to back up.
