DIY or Call a Pro? When to Tackle Plumbing Repairs Yourself

In the age of YouTube tutorials and weekend warrior projects, it's tempting to grab a wrench and fix your plumbing issues on your own. And hey—we get it! Some plumbing tasks are simple enough for a confident homeowner to handle.

But not all plumbing problems are created equal. In fact, some DIY repairs can end up costing you more in damage, time, and stress if things go sideways.

At Jim Dandy Sewer & Plumbing, we’ve seen both the success stories and the “I wish I hadn’t touched it” disasters. Here’s a breakdown to help you decide when to tackle a plumbing issue yourself—and when to pick up the phone and call a pro.

🛠️ DIY Plumbing Jobs: What’s Safe to Handle Yourself

✅ 1. Unclogging a Sink or Shower Drain

Hair, soap scum, and debris are common culprits of slow drains. A plunger or drain snake can often take care of the problem without much risk.

Tip: Avoid chemical drain cleaners—they can corrode your pipes over time.

✅ 2. Replacing a Showerhead or Faucet

Swapping out an old showerhead or faucet is a great DIY upgrade. Just make sure you turn off the water supply and follow instructions carefully.

✅ 3. Fixing a Running Toilet

Replacing a flapper or adjusting the fill valve is usually simple and inexpensive. Just be sure to use parts that match your toilet model.

✅ 4. Minor Leaks Under the Sink

If you see a drip under your kitchen or bathroom sink, tightening a connection or replacing a worn-out washer might solve the problem.

🚫 Call a Pro: When DIY Can Cost You More

🚨 1. Low Water Pressure Throughout the House

If your entire home has low water pressure, it could be caused by pipe corrosion, a leak, or a main line issue—not something a YouTube video can fix.

🚨 2. Replacing or Moving Pipes

Anything involving cutting into walls, floors, or rerouting plumbing lines should be handled by a licensed plumber. Mistakes can lead to leaks, water damage, or code violations.

🚨 3. Sewer Line Issues or Backups

If sewage is backing up into your home—or you smell foul odors from your drains—it’s time to call in the pros. These are serious issues that often require camera inspections, trenchless repair, or hydro jetting.

🚨 4. Water Heater Problems

Installing or repairing a water heater (especially gas-powered units) comes with safety risks. These jobs require expertise and permits to meet Seattle code.

🚨 5. Persistent Leaks or Water Stains

Small leaks can be signs of bigger problems hiding in your walls or under your floors. A pro can find the root cause and prevent costly structural damage.

🧠 Know Your Limits—and Your Tools

There’s no shame in calling for help. In fact, knowing when to get expert support is one of the smartest things a homeowner can do. Plumbing systems are complex, and water has a way of turning small mistakes into big problems—fast.
