ICTESS’s Pipe Sizing and Head Loss Calculation Training Course provides specialized technical training in the hydraulic sizing of plumbing and domestic hot water (DHW) installations. The program covers fluid behavior fundamentals in piping, professional calculation methods, and how to apply current technical codes.
You’ll learn the hydraulic calculations used in real installation projects: estimating instantaneous and simultaneous demand flows, determining optimal velocities based on pipe material, applying head loss formulas such as Hazen-Williams and equivalent lengths for fittings, selecting commercial pipe diameters, and verifying residual pressures at points of use. The course includes a Capstone Project where you’ll size a complete installation applying everything you’ve learned.
The Pipe Sizing and Head Loss Calculation Training Course addresses a fundamental technical need in the installations field: ensuring proper water supply in residential, commercial, and industrial buildings. Improper sizing leads to pressure problems, noisy pipes, cost overruns from oversizing, or noncompliance with the International Plumbing Code (IPC), which governs water supply installations.
The purpose of the course is to train professionals to calculate hydraulic installations with technical rigor starting at the design stage. You’ll learn to estimate flows based on fixture type and simultaneous use, determine velocities that avoid noise and erosion, calculate linear and minor head losses, select commercial diameters that meet pressure requirements, and verify sizing through field checks.
The course includes hands-on work with the standardized technical tables and hydraulic calculation charts used by professionals in the field, and concludes with a Capstone Project where you’ll develop the complete sizing of a plumbing installation, applying every competency gained in the technical modules.
The Pipe Sizing and Head Loss Calculation Training Course qualifies you for specialized technical roles at plumbing installation companies, engineering firms, technical architecture practices, and building maintenance departments. You’ll be prepared to work as an installation project technician, hydraulic calculation specialist, plumbing technical lead, or self-employed professional specializing in water supply network sizing.
The program prepares you to run complete hydraulic calculations on building projects: developing schematic diagrams with network layouts, calculating instantaneous and design flows per applicable code, sizing pipe runs based on technical and cost criteria, verifying available pressure at every point of use, and technically justifying your design decisions in project reports.
You’ll also gain skills to audit existing installations, diagnose pressure or flow deficiencies, propose resizing improvements, and perform on-site verification with measurement equipment. The program’s hands-on approach lets you apply your knowledge immediately to real-world plumbing projects.

What you'll achieve
Estimate instantaneous and design flows based on plumbing fixture type, applying simultaneity factors under applicable plumbing codes and real-use criteria.
Determine optimal flow velocities by pipe material (copper, PPR, PEX, multilayer, steel), avoiding noise, erosion, and scale buildup caused by improper velocities.
Calculate linear head losses using the Hazen-Williams or Darcy-Weisbach formulas, and minor losses in fittings using the equivalent length method.
Select commercial pipe diameters that guarantee minimum residual pressures at points of use, optimizing the balance between material cost and hydraulic performance.
Verify sizing through on-site checks using pressure gauges and flow meters, interpreting results and proposing adjustments when necessary.
The plumbing and DHW installations sector maintains steady activity tied to new construction, renovations, and remodeling. Plumbing codes such as the International Plumbing Code (IPC) require every water supply installation to be sized with proper technical rigor, which makes hydraulic calculation a required competency for designers and installers who want to meet current code requirements.
Costly errors from a lack of technical training: Improper sizing creates problems that can show up years after installation: insufficient pressure on upper floors, annoying noise from excessive velocities, or oversized piping that unnecessarily increases material costs. These errors lead to complaints, costly repairs, and reputational damage for the professional responsible.
Growing demand for technical justification: Engineers of record and code officials increasingly ask for detailed calculation reports that justify the sizing decisions made on a project. Professionals who master these calculations can produce rigorous technical documentation that backs up their design decisions under any review.
A differentiating skill in the market: While many professionals in the field rely on rules of thumb or simplified tables, mastering hydraulic fundamentals and professional calculation methods positions you as a technical specialist capable of handling complex installations with confidence in their performance.
Completing the Pipe Sizing and Head Loss Calculation Training Course positions you as a technical specialist in a core area of building installations. Correct hydraulic sizing is required on every plumbing project, and companies in the field need professionals who can run these calculations with rigor and independence.
Immediate professional differentiation: Many installers work without mastering hydraulic calculation, just following project specs. Mastering sizing sets you apart, letting you take on higher-level technical responsibilities and help develop projects, not just execute them.
Ability to solve technical problems: Understanding pressure issues, insufficient flow, or noisy installations makes you the go-to professional when no one else can solve it. This diagnostic skill is highly valued at maintenance and building technical services firms.
Independence on your own projects: If you’re self-employed or run an installation company, you’ll size your own installations without outside help, cutting costs and timelines. You’ll also justify your solutions to the project’s engineer of record or the property owner.
Recognized professional certificate: ICTESS’s professional certificate validates your technical specialization in hydraulic calculation, strengthening your position in the job market and confirming your competencies to companies in the installations sector.

Program details
The Capstone Project is the culminating stage of the course and represents the practical integration of every technical competency developed throughout the program. It consists of the complete sizing of a plumbing and DHW installation for a typical building, from the service connection to the points of use, applying professional calculation methods and current technical code requirements.
The project includes preparing a schematic diagram with the complete network layout, estimating instantaneous and design flows for each pipe segment based on fixture type, determining flow velocities appropriate to the selected material, calculating linear and minor head losses throughout the installation, and making a justified selection of commercial diameters that guarantee the minimum residual pressures required by code at every point of use.
The project also includes verifying available pressure at the most unfavorable points, sizing the pressure booster system if needed, and preparing a calculation report in the professional format expected of installation projects. The final documentation must be presented at the technical level and rigor needed for inclusion in a real construction project, demonstrating your ability to produce complete technical justifications that meet applicable plumbing code requirements.
ICTESS’s Pipe Sizing and Head Loss Calculation Training Course teaches you the professional methodologies applied on real plumbing projects. You’ll learn to calculate linear head losses using the Hazen-Williams formula, the most widely used in water supply installations, and you’ll also cover the Darcy-Weisbach equation for cases requiring greater precision. For minor losses in fittings (elbows, valves, tees, reducers), you’ll master the equivalent length method, which lets you add these losses into the linear calculation in a practical way. You’ll also learn to use standardized technical tables, hydraulic calculation charts, and structured spreadsheets that let you size installations quickly and with professional rigor.
An engineering degree isn’t required to take this course. The program is designed for professionals with technical training in installations, construction, or related fields. It’s accessible to experienced plumbing installers, mechanical and fluid systems technicians, construction managers, and any professional who works with hydraulic installations and wants to master the fundamentals of calculation. Basic knowledge of physics (concepts like pressure, flow, and velocity) and the ability to work with simple mathematical formulas is recommended. The course starts from hydraulic fundamentals and progressively builds toward professional applications, so no prior advanced calculation knowledge is required.
ICTESS’s Professional Certificate validates your technical specialization in pipe diameter and head loss calculation, documenting competencies that are highly valued in the installations sector.
