When it comes to your plumbing system, what you don't know can cost you, both in time and money. While it's easy to overlook what happens behind your walls, beneath your floors, or inside your pipes, following key plumbing rules is essential for preventing plumbing issues, improving energy and water efficiency, and ensuring your plumbing services are up to code.
In this guide, the experts at Elite Plumbing Teams break down the top plumbing rules every homeowner should understand and when to work with a professional plumber to keep your system safe, efficient, and compliant with local codes and regulations.
1. All Plumbing Work Must Follow Code
Your plumbing system is governed by a combination of the International Plumbing Code (IPC) and local codes that vary by city or state. These codes are regularly updated to ensure safety, health, and efficiency, particularly when it comes to plumbing fixtures, drainage, venting, and water supply.
Why it matters:
Unpermitted or non-compliant plumbing installation can lead to failed inspections, plumbing failures, and costly fines. It could also void your homeowner's insurance.

2. Correct Slope is Crucial for Drainage
One of the most overlooked plumbing rules is ensuring the proper slope in your drain pipes. If the slope is too steep or too flat, waste won't move efficiently, leading to blockages and even dangerous sewer gases backing up into your property.
Elite Plumbing Tip:
For most systems, a 1/4-inch per foot slope is required for optimal flow. Our licensed plumbers ensure every project follows this rule.
3. Know What Belongs—and What Doesn't—in Your System
Not all household items are flushable or disposable via your drains. Flushing anything other than toilet paper or pouring grease down the kitchen sink leads to clogged drainage systems, sewer backups, and even damage to your septic tank or main sewer line.
What not to flush:
Paper towels
Baby wipes
Feminine hygiene products
Harsh chemicals

4. Water Pressure Must Be Controlled
High water pressure may feel great in the shower, but it can be a silent destroyer of your pipes, fixtures, and fittings. Over time, it causes leaks, pipe bursts, and premature failure of your plumbing system.
A pressure regulator helps maintain safe levels and extends the life of your plumbing components.
5. Proper Venting Prevents Dangerous Gases
Every plumbing system needs air to move water efficiently and safely. Vent pipes allow air into the system, which prevents sewer gases from entering your home and helps wastewater flow properly.
Vents must be:
Sized according to plumbing codes
Installed with proper access
Positioned to avoid roof obstructions

6. Sinks and Toilets Need the Right Clearance
Plumbing fixtures like sinks, toilets, and tubs must be installed with adequate space around them. This not only ensures usability but also makes repairs and maintenance easier, and keeps your installation compliant with building and plumbing codes.
7. Always Shut Off the Water Before a Job
Whether you're replacing a faucet, fixing a leak, or upgrading a fixture, plumbing services should never begin without shutting off the water supply at the main shutoff valve.
If you're unsure where your valve is located, ask a professional plumber to show you during your next plumbing inspection.
8. Leave Specialized Plumbing Services to the Pros
From installing sump pumps and water heaters to diagnosing leaks behind walls, there are plenty of jobs best left to expert plumbers. Attempting complex plumbing repairs without the right tools, knowledge, or compliance with code can result in expensive damage, water waste, or even safety hazards.
Pro Tip: Look for contractors who specialize in both residential and commercial plumbing services, like Elite Plumbing Team.
