    Backflow Prevention Device Worker Test Prep Study Guide

    Posted by David Warner / REAL PLUMBERS on Jun 17th 2019

    I am completely astounded that PSI would offer such a useless product. The book does not have any worthwhile study information in it . They took an archaic general study guide for Plumbing, Oil Heating, and Electrical ,and repackaged it as a Backflow Prevention Device Worker Study Guide. It contains no relevant information on the subject. I want my money back !!
    To make matters worse, I bought 2 of these useless guides. I expect a full refund for both books.

    I thought it would actually be a study guide with information but it’s pretty much a bunch of practice quizzes. Not worth $50
