We are not affiliated with ASSE, which is sometimes required, especially if testing for AQUA Pennsylvania. Around 25% of water purveyors and localities do have some type of deal with ASSE.
Our course and certifications are based on the TREEO materials, so many water purveyors accept our course due to this, notable Pennsylvania American Water. Many smaller jurisdictions have no real preference and accept our course or anything equivalent.
Some places do list an American Backflow Prevention Association (ABPA) Certification, which our course is valid as a pre-requisite training and prep for this exam. The application and manual are linked below.
Since there is no state level agency regulating testers, each local jurisdiction chooses which backflow testers to accept. Most accept either ASSE or ABPA testers, but many also accept NEWWA, TREEO, or reciprocate with neighboring states.
There are a bunch of options when it comes to testing backflow preventers as far as which procedures to use. We have found that the ASSE 5000 Single Hose Procedures are most efficient if you can use them, and have fewer requirements as far as equipment, connector tees, and number of hoses and adapters needed.
On our YouTube channel, we created a series of videos where we test the four types of preventers using these procedures if you're not familiar with them:
Do you need a backflow test kit or need to calibrate a test kit you already have? We offer both of these, check out our sister company Kruger Instruments for more information:
