Tools Every DIY Plumber Needs
Before you even touch a pipe, make sure you’ve got the right tools. Using the wrong tool is one of the worst plumbing mistakes a beginner can make.
Essentials include:
- Pipe wrench
- Strap wrench
- Adjustable pliers
- Pipe cutter
- Plumber’s tape
- Bucket and towels (for unexpected leaks)
- Plunger
Top Plumbing Mistakes (and How to Avoid Them)
1. Scratching Fixtures
It’s easy to damage finishes when using metal tools. Avoid this by using a strap wrench instead of a pipe wrench on visible fixtures like chrome faucets. It grips without leaving marks.
2. Bending or Deforming Pipes
Too much pressure with the wrong tool can crush your pipes. Use a pipe wrench properly with three points of contact and apply even pressure. This preserves pipe integrity.
3. Overtightening Fittings
It may seem like tighter is better—but overtightening can crack fittings or strip threads. Use plumber’s tape and tighten just enough to seal without force.
4. Using Incorrect Fasteners
When attaching plumbing to subfloors (like for radiant heat systems), choose fasteners that won’t pierce the floor above. Always test one fastener before doing the entire job.
Avoiding Kitchen Plumbing Mistakes
The kitchen is a common place where rookie errors happen. Avoid the worst plumbing mistakes by:
- Inspecting dishwasher hoses regularly for wear or leaks
- Keeping sink drains clean and using a snake for deeper clogs
- Never pouring grease down the drain—it solidifies and causes backups
- Making sure garbage disposals are used correctly (no bones, grease, or fibrous veggies)
Preventing Bathroom Blunders
From toilets to showers, bathroom plumbing needs care. Here’s how to stay ahead of problems:
- Replace worn toilet flappers and fill valves
- Clean mineral buildup off showerheads monthly
- Fix dripping faucets ASAP to avoid water waste
- Don’t flush wipes or hygiene products—they lead to clogs
Laundry Room DIY Plumbing Tips
Even your laundry area can present hidden plumbing risks:
- Replace rubber washing machine hoses with braided steel ones
- Clean the utility sink trap regularly
- Ensure your washer is balanced to avoid leaks from vibration
Maintenance Tips for Every Home
Ongoing upkeep can prevent some of the worst plumbing mistakes:
- Flush your water heater once a year
- Check visible pipes for corrosion or leaks
- Clean drains with baking soda and vinegar monthly
- Know where your main shut-off valve is in case of emergency
What To Do When Things Go Wrong
Even pros run into surprises. Be prepared for emergencies:
- Keep extra fittings and parts on hand
- Have a wet/dry vacuum for water cleanup
- If you’re unsure, call a licensed plumber—especially if you’re dealing with gas lines or sewer connections
When It’s Time to Call a Professional
Some plumbing jobs should never be DIY. Contact a plumber if:
- You’re working near gas lines
- The main sewer line is involved
- You’ve attempted a repair but the issue remains
- You’re unfamiliar with local plumbing codes

If you’re working with gas lines, sewer lines, or experiencing repeated issues, it’s best to call a professional.
