Washington's pump specialty plumbing examination is based on the 2015 Uniform Plumbing Code and the amendments adopted by the Washington State Building Code Council, with exam questions drawn from the plumbing-code provisions that apply to domestic pump and pump-and-irrigation work.\u003c\/p\u003e\n\n\u003cp\u003eWashington recognizes two related specialty plumber certifications in this area: \u003cstrong\u003ePump \u0026amp; Irrigation (PL03)\u003c\/strong\u003e and \u003cstrong\u003eDomestic Well (PL03A)\u003c\/strong\u003e. The PSI examination is identified as the \u003cstrong\u003eDomestic Pump or Irrigation Specialty Plumber\u003c\/strong\u003e examination. Candidates pursuing either pathway should understand the differences between the certifications, including the type of equipment and systems each specialty may work on and the experience requirements established by Washington.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ePL03 Pump \u0026amp; Irrigation\u003c\/strong\u003e specialty is limited to installation, maintenance, and repair of equipment used to acquire, treat, store, or move water suitable for drinking or irrigation purposes. The \u003cstrong\u003ePL03A Domestic Well\u003c\/strong\u003e specialty covers qualifying domestic water pumping systems and has additional limits involving pump capacity and electrical characteristics.\u003c\/p\u003e\n\n\u003cp\u003eThe examination is \u003cstrong\u003eopen book\u003c\/strong\u003e and consists of 45 questions with 90 minutes allowed.
