ExploreAbout this exam
The Master Plumber Licensure Examination (MPLE) is the Philippine licensure examination administered by the Professional Regulation Commission (PRC) for candidates who want to be registered master plumbers. The PRC's official passers list for the Certificate of Board Rating and Passing covers Master Plumber passers from February 2010 to date, which confirms the MPLE as a long-running PRC-regulated examination. This page is an independent study resource for candidates preparing for that examination. It is not affiliated with, endorsed by, or connected to the PRC or the Professional Regulatory Board for Master Plumbers. The review material here is organised around four domains: plumbing code and standards; plumbing system design and installation; plumbing materials, fixtures, and fittings; and plumbing laws, ethics, and professional practice. Each domain carries equal emphasis in this study plan. To prepare, work through the domains in order, starting with code and standards because they anchor design decisions, then move to design and installation, then materials and fixtures, and finish with laws and ethics. Practise applying code provisions to realistic scenarios rather than memorising lists. Verify all official requirements, schedules, and procedures directly with the PRC through its official website and published Citizen's Charter before acting on anything you read here.
What you'll study
About MPLE Board Exam preparation
Who administers the Master Plumber Licensure Examination?
The Professional Regulation Commission (PRC) administers the MPLE. The PRC lists Master Plumber among the professions whose passers from February 2010 to date must secure an online appointment when requesting a Certificate of Board Rating and Passing. Always confirm examination details through the PRC's official website rather than third-party pages.
Is this page officially connected to the PRC?
No. This is an independent study resource and claims no affiliation with the PRC or the Professional Regulatory Board for Master Plumbers. The PRC has warned the public about unofficial websites and Facebook pages that use its logo, and it states it is not involved in producing, selling, or distributing review materials for licensure examinations.
How should I order my study across the four domains?
Start with plumbing code and standards, since code provisions govern design decisions and material selection. Move next to plumbing system design and installation, then materials, fixtures, and fittings, and finish with laws, ethics, and professional practice. Revisit code topics at the end, because later domains keep referring back to them.
What are the most common ways candidates lose points?
Typical failure modes are memorising code numbers without knowing when a provision applies, confusing fixture and fitting terminology, and neglecting the laws and ethics domain because it feels less technical. Practise scenario-based questions that force you to choose between two plausible provisions, and review ethics and professional practice as seriously as design topics.
How do I request a Certificate of Board Rating and Passing after passing?
If you passed in February 2010 or later, the PRC requires you to secure an online appointment before requesting the certificate. Passers from earlier periods are advised to make the request as walk-in clients at any PRC Regional Office and Service Center. Check the PRC website for the current procedure.
Does the PRC sell or endorse review materials for the MPLE?
No. The PRC states it is not involved in the production, sale, and distribution of review materials for licensure examinations, does not endorse or advertise them, and is not affiliated with sellers or distributors, including those near PRC premises. Proximity to the PRC office does not guarantee quality or credibility.
Someone offers to help me pass the exam for a fee. Should I accept?
No. The PRC warns examinees against fixers who pose as or claim to know Board Chairpersons, Members, or PRC officials and employees, and who offer to help examinees pass or facilitate transactions for money. Report such offers to the PRC Licensure Office or Legal Service using the contact details published on the official PRC website.
Where can I verify that a website or page is officially PRC?
The PRC lists its official websites as www.prc.gov.ph, online.prc.gov.ph, cpdas.prc.gov.ph, and crms.prc.gov.ph, and its official Facebook page as facebook.com/professionalregulationcommission. It disclaims liability for information appearing on other sites that present themselves as official. Verify through these channels before relying on any announcement.
Where are PRC public transactions handled now?
Effective October 2025, all public transactions of PRC – National Capital Region are conducted at ETON CENTRIS, Quezon Avenue, Quezon City, with different cyberpods for regulation and registration transactions. The PRC Main Office in Sampaloc, Manila no longer accepts public transactions. Confirm your specific transaction location on the PRC website before travelling.
What should I check before relying on any MPLE schedule or requirement I find online?
Check the PRC's official website and its Citizen's Charter, which sets out requirements and timelines for releasing documents. The PRC disclaims responsibility for the accuracy of information on unofficial sites. Treat schedules, fees, and procedures from any other source as unverified until confirmed through official PRC channels.
