This addition of Test Your Skills will look at safety concerns related to cross-connection control testing and surveys related to confined spaces and other hazards. We always need to put safety front and center and understand the actual and potential hazards. Let’s dig a little deeper into this part...

This edition of Test Your Skills will look at hydraulics and its relationship to cross-connection control and backflow prevention. How and why water moves, along with what happens in water systems as a result of the installation of backflow prevention valves is knowledge individuals working in the field...

The need for cross-connection control for fire protection systems at times makes for interesting discussions. What, if any protection is required? How do we decide on the correct degree of hazard? Should we look to the plumbing code or is the NFPA Standards the correct reference books we need?  Let’s...

In this installment of Test Your Skills we will look at one of the consequences of the installation of cross-connection protection on water systems. Let’s look at the phenomenon we call thermal expansion. We will dig a little deeper into this part of the cross-connection puzzle. It’s time to pick...

The correct use of field test procedures is how we ensure that backflow prevention assemblies will provide the necessary protection to the water system. Any mechanical device or assembly can fail and a robust testing program is needed in any quality cross-connection program. The industry may disagree...

In this issue’s installment we will look at test procedures used in different parts of the United States. All types of cross-connection control must be installed correctly to provide the necessary protection required. It then needs to be tested and maintained to keep it in good working order. Let’s...
