Understanding Plumbing in the Kitchen

Your kitchen, a central hub in your home, is equipped with numerous appliances and fixtures, all dependent on a well-functioning plumbing system. Today, our goal at Wagner is to decode and clarify the intricate network of pipes and fittings that constitute your kitchen's plumbing. Whether you're fitting a new kitchen or modernizing an old one, this guide is designed to help you grasp the fundamental elements of kitchen plumbing.


Dishwashers require both water supply and drainage systems. The supply line, typically a 3/8” pipe, provides hot water to clean and sanitize your dishes. This hot water is usually supplied from your home's main water heater.

The drainage system, on the other hand, carries away the dirty water after the wash cycle. It usually connects to the kitchen sink's drainage system and requires an air gap or high loop installation to prevent backflow or any wastewater from entering the dishwasher again.

Kitchen Sink

The kitchen sink, one of the busiest places in the kitchen, is a crucial part of your kitchen's plumbing system. It includes both water supply and drainage systems. Supply lines provide hot and cold water to the faucet, allowing you to adjust the water temperature as needed for various tasks.

The drain system carries away wastewater. It typically includes a P-trap, a U-shaped pipe that traps a small amount of water to prevent sewer gasses from entering your kitchen. If you have a double sink, both basins will connect to a common drain line.

Garbage Disposal

Garbage disposals are handy kitchen appliances installed under the sink.They're connected to the sink's drain line and require electricity to operate. When switched on, they chop up food waste into tiny pieces, small enough to pass through the drain pipe and prevent clogs.

Garbage disposals need to be used with water running to facilitate the grinding and flushing of food particles down the drain. Overuse or improper use of garbage disposals can lead to plumbing issues, so it's essential to use them appropriately.

Fridges & Ice Makers

Modern refrigerators often come with water dispensers and ice makers, requiring a dedicated water supply line. This is typically a small, flexible tube that runs from a water source to the back of the fridge.

The ice maker uses this water to freeze ice, while the water dispenser provides chilled water on demand. It's crucial to ensure that this line is correctly installed to prevent leaks or water damage.
