The plumbing system or diagram in residential and commercial buildings is responsible for delivering fresh water and removing wastewater efficiently. This comprehensive system includes distribution pipes, plumbing fixtures, vent pipes, sanitary sewers, and building drains, all requiring proper connections to function correctly.
Every building area requires a well-designed plumbing system to prevent future issues such as water leakage, clogging, hot water shortages, sewer problems, and faulty faucets. Plumbing systems are installed according to a detailed Plumbing Plan that illustrates components, dimensions, sizes, and orientations. EdrawMax provides multiple plumbing plan templates, allowing users to easily modify existing plans or create custom designs using standardized signs and symbols.

- Basic Plumbing Plan Examples
1.1 Water Supply Plumbing System Examples
The water supply system forms a critical component of any plumbing installation, responsible for delivering water to toilets, showers, taps, bathtubs, sprinklers, and appliances including washing machines, steamers, and water heaters. This system incorporates various plumbing components such as pipe fittings, water pipes, connectors, service valves, and faucets. Water pipes are typically constructed from plastic, copper, or galvanized iron materials.
Example 1: Water Supply Plumbing Plan
Water systems are designed to facilitate efficient water flow throughout buildings, with configurations varying based on distribution purposes including drinking, cooking, cleaning, washing, plant watering, animal hydration, and garden/field irrigation. Water distribution extends to kitchens, bathrooms, gardens, laundry areas, garages, and pool areas. Based on these factors, water supply plumbing systems are categorized into four main types:
- Dead-end or Tree Distribution system
- Gridiron Distribution System
- Circular or Ring Distribution System
- Radial Distribution System
This water supply system plan demonstrates water flow from bottom tanks to top tanks and subsequent distribution throughout building sections.
Example 2: House Tap Water Supply Plumbing Plan
This house tap water supply plumbing plan illustrates residential plumbing configuration with different colored lines representing various plumbing pipes. Blue bars indicate freshwater supply entering the house. Residential plumbing divides into two basic systems: clean water delivery and wastewater removal, with fixtures (sinks, showers, toilets, washing machines, dishwashers) connecting between these systems. Once inside, clean water supply separates into cold and hot water systems as shown in this detailed plan.
Example 3: Apartment Plumbing Plan
This apartment plumbing plan demonstrates hot and cold water supply systems for residential units. Apartments require efficient plumbing systems serving multiple units with centralized water distribution. The plan shows coordinated plumbing infrastructure ensuring proper water pressure, temperature control, and waste removal across different apartment levels and units while maintaining building structural integrity and code compliance.
1.2 Drain Waste Vent Plumbing System Examples
The Drain-Waste-Vent (DWV) system represents the most critical component of any plumbing system, also known as the sanitary system. It encompasses all plumbing elements except water supply, designed to carry wastewater from sinks, taps, bathtubs, showers, toilets, and appliances like dishwashers and washing machines to septic tanks or public sewers. This system ensures clean water delivery while efficiently disposing of waste and sewage. DWV pipes and connections are typically concealed underground or within walls. The system facilitates air entry to maintain proper pressure and remove drain waste and greywater from residences, utilizing two pipe types: Drain-Waste pipes and Vent pipes.
Example 4: Drain-Waste-Vent Plumbing System
Drain-Waste pipes transport actual waste from sinks, toilets, showers, bathtubs, and various appliances to main sewers or septic tanks. Vent pipes serve dual functions: ventilating sewage gases through roof exhaust pipes and providing necessary air to drain-waste pipes for smooth, silent sewage drainage. This drain-waste-vent plan illustrates bathroom plumbing connection orientation and configuration.
Example 5: Drain Water Vent Plumbing
Residential properties typically feature at least one main stack as shown in this Drain water vent plumbing plan. The stack is a large vertical pipe (often 3-4 inches diameter) running from above the roof to the main sewer line. Horizontal drain and vent pipes connect from various toilets, faucets, tubs, and appliances into the main stack. Horizontal drain pipes require proper sloping to prevent water accumulation. Venting complexity is balanced by simple principles: vent pipes allow air entry behind drain water facilitating smooth flow. Unvented drain water can gurgle similarly to water exiting an upturned thin-necked bottle.
Example 6: Drain Water Vent Plumbing System
This drain water vent plumbing plan illustrates systems maintaining proper air pressure through air entry, enabling efficient sewage and greywater removal from dwellings. Fixture-produced water from sinks and showers is classified as drain water, while toilet water is designated waste water. Proper venting prevents vacuum formation during drainage, allowing free water flow. Air must enter waste pipes during water drainage through roof vents (external) or internal vents. The system maintains neutral drain air pressure, facilitating smooth water and sewage flow through drains and waste pipes.
1.3 Kitchen Plumbing System Examples
Kitchen plumbing requires careful installation and testing due to potential gas leakage and fire hazard risks. Kitchen plumbing layout plays a vital role in planning safe, efficient systems. Typical kitchen plumbing includes hot/cold water supply lines, sink waste lines, gas range connections, and gas supply pipes. Additional components often connected to sink plumbing include dishwasher disposal hookups, ice maker connections, and instant hot water appliances.
Incorrect kitchen plumbing installation can cause sink malfunction, sewer gas leakage, and damaged slip nuts. Basic kitchen plumbing process steps include:
- Hire qualified plumbing contractors
- Install proper drainage systems
- Place appropriate traps
- Install Air Admittance Valves
- Install pipes and connections
- Establish supply systems
- Install kitchen sinks
- Install garbage disposal systems
Example 7: Kitchen Plumbing System
A kitchen plumbing diagram depicts a complicated network of water supply pipes, drain pipes, vent pipes, and other components. Because plumbing is a complex system that is one of the most expensive to repair or install in a home, it is essential to understand how it works. Understanding the concept of a plumbing system allows you to understand the types of problems better. If you are planning for a remodel or a new home, a Kitchen plumbing diagram can help you in designing a system that will work adequately to pass plumbing codes. In major plumbing work, consider the following: A properly designed system will efficiently deliver water to the faucets, fixtures, and water-using appliances while carrying wastewater away without clogging.
Example 8: Kitchen Plumbing Plan
Following finishing work and kitchen furniture installation, the kitchen plumbing is connected to the water supply and sewerage system, as shown in this Kitchen plumbing plan. Use the flexible piping elements that come with this type of plumbing to connect the dishwasher in the kitchen. As previously stated, the sewer connection is made through a water seal to prevent the formation of unpleasant odors. To avoid gurgling in the sink, connect the dishwasher with a special valve, as shown in this Kitchen plumbing plan. A water filter is usually installed in the kitchen under the sink.
1.4 Bathroom Plumbing System Examples
A bathroom is a room to perform basic body cleaning. So, water supply and plumbing systems are the leading systems installed in a bathroom. The bathroom is where the plumbing system is the most needed. In a bathroom, a plumbing system must deliver clean water and take the waste and sewage out of the dwell. The bathroom plumbing system consists of water supply plumbing and the Drain-Waste-Vent system. The standard size of the sink's pipe is 1.25 inches in diameter.
The standard bathroom plumbing system is usually based on five waterlines:
- Cold waterline for toilet
- Cold and hot water for sinks, showers, and bathtubs
- Flexible lines for hot and cold waterlines
Example 9: Bathroom Plumbing Diagram
The bathroom plumbing plan demonstrates the plumbing connection in a bathroom where tub shower, tub drain, tub trap, vent stack, closet bend, toilet water supply, air chambers, lavatory water lines, lavatory chains, and cold hand ot water pipelines. The vent stack is directly connected to the toilet and indirectly to the bathtub/shower and takes out the waste.
Example 10: Bathroom Plumbing Plan
To create a bathroom plumbing plan, draw all fixtures to scale and ensure that they are not too close together. Mark the drain and vent lines for the institutions before adding the supply lines. Create riser drawings that include vertical pipe runs as well. A bathroom plumbing plan depicts the system that will bring water in and remove waste. Water supply lines, drains, vent pipes, valves, and fixtures such as toilets and sinks are common components. These plans frequently use a variety of official plumbing symbols to denote different elements, and producing plan views and riser drawings by hand or on a computer is fairly simple.
Example 11: Bathroom Plumbing System
Installing a bathroom plumbing system typically entails installing a system of pipes, drains, valves, and other fittings for water distribution. The current trend is to have concealed plumbing, so it is critical to avoid any mistakes, as any minor re-do work will require you to break wall tiles. A general understanding of bathroom plumbing will help you know if you're remodeling or redesigning your bathroom. It will be useful when remodeling or updating your toilet, but it is also useful to know if something goes wrong with your bathroom plumbing - you will know what the issue is and possibly how to fix it.
1.5 Basic Plumbing Plan Examples
A plumbing plan or a plumbing drawing is a technical overview of the system that shows the piping for freshwater going into the building and waste coming out. In most architectural projects, you will learn that a plumbing plan includes drawings of the water supply system, drainage system, irrigation system, stormwater system, etc. At the same time, a plumbing plan drawing will differ from building to building. For instance, a residential plumbing layout plan would differ from a general plumbing layout plan or a commercial complex.
Example 12: Plumbing Plan for House
Plumbing and piping plans and fixtures installed in a building for the distribution and use of drinkable water and the removal of waterborne wastes. A plumbing and piping plan is usually distinguished from water and sewage systems serving a building group. The plumbing and piping plan example shows several types of plumbing systems in building construction: single stack system, partially vented single stack system, one-pipe system, and two-pipe system.
Example 13: Plumbing Plan Layout
This plumbing layout plan depicts fixtures, water supply, waste-disposal lines, equipment, and other sources of supply and disposal. This Plumbing Layout Plan is much easier to understand and is invaluable to those in charge of preparing material estimates and the craftspeople installing plumbing systems. The first stage of any project is the concept and design. The next step is to create construction drawings when everything is in place. When a floor plan is finished, it is given to the mechanical engineer, who will generate plumbing drawings. The illustrations are added to the construction-drawing set. A set of construction drawings' mechanical division will include, in addition to plumbing plans and details, drawings for any heating, ventilation, and air-conditioning systems a building may have.
Example 14: Plumbing Plan Example
A well-constructed plumbing plan drawing in core building setups will depict the housing system that will bring water in and take the wastewater (in liquid and solid form) out of the house. Before you set out to make your plumbing plan using EdrawMax, you should understand what is included in a plumbing plan drawing.
