DIY Repair
Handling straightforward repairs (a running toilet, a leaky faucet) personally using parts from a hardware store.
- Low cost for simple fixes
- Immediate — no waiting for a service appointment
- Risk of water damage if a repair is done incorrectly
- Some work (gas lines, sewer connections) requires a licensed professional and permit
Licensed Plumber
A licensed professional diagnoses and repairs the issue, with code-compliant work and typically a warranty.
- Code-compliant work, important for resale and safety
- Warranty on the repair in most cases
- Necessary for gas lines, sewer work, and other regulated plumbing
- Higher cost than DIY for simple fixes
