Plumbing Shop Drawings: A Critical Component for MEP Contractors
Plumbing shop drawings are a necessary tool in the design and installation of plumbing systems within any construction project. These particular plumbing drawings define every element of the plumbing system, from Domastic water supply and drainage to stormwater control management. At Cadeosys, we Expedite plumbing drafting service, tailored to meet the unique requirements of each project as per required international plumbing code or state to state codes. Our expert team ensures that every pipe, valve, fixture, and material is specified, correctly routed, and installed with highest project as per required international plumbing code or state to state codes
What Are Plumbing Shop Drawings?
Plumbing shop drawings are specific blueprints that illustrate how the plumbing system could be applied in a building or facility to better understand and easy installation by a foreman and even for a layman. These drawings function the roadmap for contractors, offering essential records on:
Pipe Sizes and their routing
Elevations on pipes to make sure there are no clashes between internal piping as well for better positioning sleeves / penetrations.
Plumbing Fixtures like faucets, toilets, sinks, etc.,to match as per the Carrier connections.
Valves and their exact placements as per approved submittals will be helpful for preparing plumbing shop drawing.
Materials used in the plumbing system (such as copper, PVC, or PEX )to match LOD’s and can take BOM/BOQ.
System Specifications such as pressure ratings, flow rates, and types of joints as per approved submittals.
These plumbing shop drawings are essential for ensuring that all components of the plumbing system fit together and operate efficiently, preventing costly errors during construction.
Types of Plumbing Systems Covered in Shop Drawings
Our plumbing shop drawings at Cadeosys cover a wide range of plumbing systems, making sure that each one areas of the constructing are well-prepared and purposeful These include:
1. Water Supply Drawings
Water supply drawings detail the distribution of potable water throughout the building. These drawings cover everything from the main water supply entry point to the final fixture. The key elements in water supply drawings include:
Water main connections
Pipe sizing for adequate pressure
Make sure to keep RPZ, A specialized valve designed to prevent backflow and safeguard the water supply from contamination by creating a reduced pressure zone within the plumbing system; essentially functioning as a backflow prevention device.
Branching systems to supply water to various floors and sections


Hot Water: Ensuring the efficient distribution of heated water for showers, cooking and to keep return pump for maintain hot water and more…
Domestic Water: Supplying potable water for everyday use like drinking and cleaning.
Recalculated Water: Custom-designed systems for high-demand buildings or unique water requirements.
Soft Water: Reducing water hardness to prevent scale buildup and protect plumbing fixtures.
2. Drainage System Drawings
Drainage system drawings ensure that wastewater is efficiently removed from the building, whether from kitchens, bathrooms, or storm water runoff. Drainage systems must be carefully designed to avoid blockages or flooding. Our drainage shop drawings include:
Sewer line routing
Trap placement to prevent odors and maintain a seal
Vent piping for proper air circulation
Slope and grading to ensure optimal flow
3. Irrigation System Drawings
Irrigation system drawings detail the distribution of water for landscaping and gardening purposes. They include:
Pipe routing for irrigation lines
Valve locations for controlling water flow
Sprinkler and drip line placements for efficient water usage
Rainwater harvesting systems for sustainable irrigation solutions
4. Storm water Management Drawings
Storm water management is essential to prevent flooding and water damage. Our storm water drawings include:
Drainage pathways for managing surface water
Catchment basins and infiltration systems
Stormwater pipe systems to direct excess water away from the building and requirement of detention tanks.
Green infrastructure solutions like bioswales and permeable pavements
Our team of experts ensures that all plumbing systems are designed to function efficiently while complying with local regulations and standards. Our drawings ensure smooth integration with other MEP systems, such as HVAC, Fire system and electrical, to avoid conflicts between systems. This helps ensure that the building’s infrastructure works cohesively and efficiently.
