PipePro Suite
Executive Summary
Vision Statement
Empower every plumber and contractor with instant, reliable, and code-compliant calculation tools—eliminating friction, boosting accuracy, and making professional plumbing accessible anywhere.
Problem Summary
Plumbers, contractors, and DIYers frequently waste valuable time switching between multiple websites, apps, or reference books to perform essential plumbing calculations—like pipe sizing, pressure loss, drain/vent sizing, and equipment selection. This fragmented workflow is inefficient, especially on job sites with poor connectivity, and can lead to errors or delays in project execution.
Proposed Solution
PipePro Suite provides a comprehensive, mobile-optimized web and (optionally) mobile app platform offering a suite of plumbing calculators. These tools cover pipe sizing, pressure loss, drainage and vent sizing, water heater and expansion tank sizing, pump selection, hydraulic calculations, and more. The platform delivers instant, reliable results—offline-capable and free of ads or registration—streamlining the workflow for plumbing professionals and serious DIYers.
Market Analysis
Target Audience
The ideal user is a licensed plumber, plumbing contractor, or field technician aged 25–55, working in residential or commercial construction or maintenance. Secondary audiences include HVAC technicians, building engineers, and advanced DIYers. They value speed, accuracy, and mobile accessibility, often working in environments with limited internet and requiring quick, code-compliant calculations on the go.
Niche Validation
The Reddit post and its comments provide strong validation for the core problem: users express appreciation for a unified, ad-free, mobile-friendly suite of calculators, with several suggesting further feature expansion (e.g., oil/water separator sizing) and even advocating for a mobile app version. The high upvote ratio (0.97) and positive, grateful feedback indicate real demand and pain point alignment.

Market Size Estimation
The Serviceable Available Market focuses on English-speaking professionals in North America and Europe who use digital tools for plumbing calculations—estimated at 1–2 million active users, including contractors, technicians, and advanced DIYers.
The Serviceable Obtainable Market for a new SaaS platform with effective marketing and niche targeting could realistically capture 1–3% of the SAM in the first 2 years, or roughly 10,000–30,000 monthly active users.
The Total Addressable Market includes all professional plumbers, contractors, and building engineers globally. According to the U.S. Bureau of Labor Statistics, there are over 500,000 plumbers in the U.S. alone, with global numbers exceeding 5 million when including related trades and serious DIYers. The broader market also includes students in trade schools and apprenticeships.
Competitive Landscape
Competitors include established web tools like PlumberCalc.com (source), mobile apps such as Pipe Trades Pro and EasyPipe, and general engineering calculators. However, most competitors either require payment, are cluttered with ads, lack offline functionality, or are not mobile-optimized. PlumberCalc.com is currently free, but the lack of a dedicated mobile app and potential for advanced features (like user project saving, code compliance checks, or integrations) leaves room for differentiation.
Product Requirements

Defensibility Moat
Defensibility can be built through network effects (user-contributed calculators or code updates), integration with industry standards and local codes, and a reputation for accuracy and reliability. Building a strong brand and user community, plus offline-first technology, increases switching costs.

Business Strategy
Monetization Strategy
Adopt a freemium model: keep core calculators free and ad-free, but offer premium features (e.g., project saving, PDF exports, advanced code compliance checks, integrations with estimating software) under a monthly or annual subscription. Alternatively, monetize via a white-label B2B offering for contractor firms or trade schools.
Financial Projections
Assuming 2% conversion of 20,000 monthly active users to a $10/month premium plan yields $4,000 MRR. With B2B partnerships or white-label deals, MRR could grow via larger contracts. Growth depends on continued feature expansion and user trust.
Tech Stack
Node.js with Express for rapid API development and server-side rendering. For more computationally intensive calculations, Python with FastAPI could be used for microservices.
PostgreSQL for structured user/project data, with Redis for caching frequently used calculations. If only stateless calculators, a minimal database may suffice.
Next.js for its SEO, performance, and excellent offline/PWA capabilities, ensuring fast load times and mobile optimization.
Stripe for payments, AWS S3 for file/PDF exports, SendGrid for transactional emails, and Sentry for error monitoring. Optionally, OpenAI API for AI-powered code compliance suggestions.
Risk Assessment
Identified Risks
- Free competitors (like PlumberCalc.com) may limit user willingness to pay.
- Calculation errors could harm user trust and reputation.
- Low adoption if not integrated into existing contractor workflows.
Mitigation Strategy
- Differentiate with advanced features, offline-first app, and superior UX. Offer white-label or B2B integrations.
- Rigorously validate all formulas, provide disclaimers, and allow user feedback/reporting for errors.
- Partner with trade schools and associations to drive adoption and integrate with popular estimating/project management tools.
