Can I fix this myself, or do I need to call a professional plumber? There’s a very good chance, as a property owner, you have asked yourself this question at least once.
For some of you, your first instinct might be to pull up a video online and head to the hardware store. After all, saving money on home repairs is a high priority for all homeowners.

At Baethke Plumbing we have over 30 years of dealing with every kind of plumbing issue in the Chicagoland area you can imagine, from a leaking faucet to re-piping an entire house, we want to tell you one simple thing… You do not need to call us for everything. This may surprise some of you. However, we want you to repair the simple stuff on your own. It saves you money, and it keeps our plumbers available for more jobs that require a licensed plumbing contractor.
In the guide below, we will talk about what constitutes a DIY job and when you should call a professional plumber. We will summarize the economics of plumbing, DIY risks, evaluate costs, and give you an honest framework to decide when to pick up a wrench and when to pick up the phone.
DIY Plumbing Economics 101
When evaluating DIY plumbing repairs, your mind will most likely go to: Cost of a Plumber vs. Cost of Retail Parts.
If a new kitchen faucet costs $100, and a plumber charges $600+ to install it, doing it yourself looks like an automatic $600+ win. However, this equation leaves out the 4 most critical hidden costs of DIY plumbing: Tool Tax, Liability Gap, and Time Investment, Misc. Plumbing Items required for installation.
The “obvious” math ($600+ saved) only holds if you ignore what it costs to actually do the job, once you factor in the tools or parts you may need to buy, your own liability if you cannot fix the issue correctly, and the hours it will consume out of your day or weekend, suddenly that $600+ in savings looks a lot thinner.
DIY Plumbing Projects for You
The good news is there are many household plumbing tasks which are perfectly safe for beginners or intermediate DIYers.
Please keep in mind that this will all come down to your individual comfort level when it comes to repairs. If you are thinking about fixing something and have questions, please call us! We will ask the questions that are going to test you on your comfort level, and we’ll give you warnings about what can go wrong.
And don’t forget, YouTube is a great source of informational videos on plumbing. You could probably learn how to do the plumbing for your entire house on YouTube. As long as your repairs are done the right way, with all the proper permits and you are up to code, you can do as much DIY plumbing as you feel comfortable with.
The projects below generally have low risk, require minimal specialized tools, and are time efficient.
- Toilet Tank Resets
If your toilet is constantly running, ghost flushing, or trickling, you rarely need a plumber. Replacing the rubber flapper, adjusting the lift chain, or swapping out the entire fill valve assembly takes less than twenty minutes. The parts cost under $20, and the water can be isolated easily using the fixture’s local shut-off valve. Note: When replacing parts in your toilet, make sure you use the exact parts made for your specific model, including bolts, gaskets, the water supply line, and possibly the emergency shut off valve. Leaving old, mismatched, or worn components in place can lead to catastrophic failure.
- Minor Faucet Upgrades
Swapping out an old, outdated bathroom or kitchen faucet is highly achievable. Modern faucet kits come with flexible supply lines and explicit instructions. If the shut-off valves underneath your sink are fully functional and turn off completely, this is a fantastic weekend project.
- Clearing Simple Sink Clogs
When a bathroom sink slows down due to hair and soap scum, you don’t need a heavy motorized drain machine. Clearing out the P-trap (the U-shaped pipe under the sink) with a bucket underneath, or using a cheap plastic drain-cleaning tool (a “zip-it”), will solve the issue 90% of the time.
Emergency Plumbing: Signs You Must Call a Licensed Plumber
On the other side of the coin are projects which carry massive structural, financial, or safety risks.
| Issue | Why You Should Call a Plumber | What’s Needed |
| 1. Main Sewer Line Backups | Handheld retail snakes cannot reach or clear mainline blockages, which cause toilet water to bubble into tubs or multiple drains to back up. | Commercial-grade sewer machine or hydro-jetter, plus a camera inspection to confirm pipes are not compromised. |
| 2. Natural Gas Lines | A minor mistake with water plumbing means a puddle; a minor mistake with gas can mean an explosion or deadly carbon monoxide poisoning. | A professional with a specific gas-fitter license. |
| 3. Water Heater Replacements | Involves high-voltage electricity or natural gas, strict codes, and relief valves. Improper installation can turn the unit into a rocket or cause electrical fires. | Licensed, experienced installation. |
| 4. Behind-the-Wall Pipe Repairs | Requires specialized soldering torches or precise chemical bonding inside drywall cavities, opening up core distribution infrastructure. | A professional contractor who does this work daily. |
| 5. Active, Uncontained Water Leak | Mismanaging a live, pressurized leak can quickly flood a home, ruin structural framing, destroy electrical systems, and cause thousands in immediate water damage. | Immediate main water shutoff, followed by a professional with commercial structural drying gear and heavy-duty pipe-repair tools. |
| 6. Organic Growths | Organic growth colonies release airborne spores that pose severe respiratory health risks and can spread the contamination to the rest of the house. | Certified organic growth remediation specialist with containment barriers, negative air pressure machines, and PP |
If your problem falls into any of the above categories, step away from the toolbox and call a plumbing professional.

Frequently Asked Questions
- What’s safe to DIY?
Simple fixes with low risk of water damage: replacing a toilet flapper, unclogging a drain with a plunger or hand auger, replacing a showerhead or faucet aerator, or swapping out a supply line. These all use basic tools you probably have at home and don’t involve cutting into pipes, walls or gas lines.
- When should I stop and call a plumber?
Any job involving gas lines, sewer lines, or water heater installation, these carry safety risks (gas leaks, carbon monoxide, scalding) and often require permits. Also you should call a professional if a “simple” fix uncovers something bigger in your home, like corroded pipes, low water pressure throughout the house, or water stains suggesting a hidden leak.
- What’s the risk of DIY-ing the wrong job?
Beyond the safety issues, a botched repair often costs more in the end, a cracked fitting or improperly sealed connection can cause water damage that turns a $150 fix into a $1,500 one. If you’re unsure, a quick call to check is cheaper than guessing wrong.
