PPE practice questions - frequently asked questions

Plain answers about how PPE Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real PPE exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The PPE exam spans 9 domains: General Requirements; Fixtures; Water Heaters; Water Supply and Distribution; Sanitary Drainage; Vents; Traps, Interceptors, Separators, Special Piping, and Storage Systems; Storm Drainage; Health Care Plumbing. Every practice question on this site is tagged to one of these domains.

The PPE exam has 60 questions and is completed in 2 hours 30 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
