Taking the DIY route with plumbing might seem like a smart way to save money, but for many Beaverton homeowners, it often leads to expensive regrets. Plumbing is a highly technical trade that relies on precision, code compliance, and experience—something most DIYers lack. Whether it’s a small leak under the sink or installing a new water heater, what seems simple can quickly escalate into costly water damage or code violations.
Before grabbing that wrench, here are the most common DIY plumbing mistakes homeowners in Beaverton make—and how to avoid them.
1. Overtightening Connections
A classic rookie move: believing “tighter is better.” When tightening pipe fittings, many DIYers end up cracking the threads, causing leaks down the road or immediate damage.
Common mistakes:
- Overtightening supply lines or toilet bolts
- Cracking plastic fittings
✅ Pro tip: Finger-tight and a quarter-turn with a wrench is often enough.
2. Using the Wrong Tools
In plumbing, the right tool makes all the difference. Using an adjustable wrench where a pipe wrench is needed, or skipping Teflon tape, can lead to poorly sealed joints or stripped fittings.
Must-have tools include:
- Pipe wrench
- Basin wrench
- Teflon (PTFE) tape
- Plumber’s putty

3. Improper Use of Drain Cleaners
Chemical drain cleaners may seem like a quick fix for clogs, but they can corrode your pipes over time, especially if used repeatedly on older plumbing systems.
Instead, consider:
- Using a plumbing snake
- Trying a plunger
- Calling a professional for hydro jetting if clogs persist
⚠️ According to Angi’s guide on common DIY plumbing mistakes, chemical misuse is one of the top causes of pipe damage.
4. Neglecting to Shut Off the Water Supply
This one’s a heartbreaker. Imagine cutting a pipe and getting blasted with water because you forgot to turn off the main valve.
Always:
- Shut off the main water valve before starting any repair.
- Drain the lines by opening a faucet at the lowest point in your home.

5. Incorrect Slope for Drain Pipes
Gravity is essential in drain systems. If your pipes don’t slope correctly—too flat or too steep—water won’t flow properly, leading to blockages or sewer odors backing up.
The standard is a ¼ inch per foot of horizontal run. Anything off that may cause serious issues.
6. Mismatched Pipe Materials
Mixing copper with galvanized steel? That’s a recipe for corrosion. Some metals react chemically, leading to electrolysis, which can rapidly degrade your plumbing.
When in doubt:
- Use dielectric unions when connecting dissimilar metals.
- Stick to compatible materials, and know your pipe types.
7. Skipping Permits and Code Compliance
In Beaverton, certain plumbing jobs require a permit. Failing to pull one can:
- Violate local plumbing codes
- Risk fines during home resale or inspection
- Void your homeowner’s insurance in the event of water damage
8. Ignoring Small Leaks
A slow drip under the sink? Many homeowners let it go for weeks—until mold, cabinet rot, and water damage set in. Even minor leaks can waste hundreds of gallons of water per year and lead to massive bills.
