In this month’s column, learn how the term “gaslighting” came about and how gas pressure affects gas lights. Plus, IAPMO is looking for comments on the new versions of the Water Efficiency Standard; the Uniform Solar, Hydronics and Geothermal Code; and the Uniform Swimming Pool, Spa and Hot Tub Code.

The debate continues on whether corrugated stainless-steel tubing is a safe distribution method for fuel gas. The answer depends on the application. Read on to discover the history and uses of this flexible product.

The plumbing and heating industry has several standards covering water temperature in water distribution systems and plumbing fixtures to prevent scalding and Legionella bacterial growth. Read on for an explanation of three new standards focusing on water heaters.

Read on for step-by-step instructions on sizing drainage systems, including how to determine the flow rate of boiler effluent and cooling water, as well as the required pipe sizes.

After a renovation project, a physical plant stationary engineer fell into the overflow of scalding hot boiler effluent; he eventually died of his injuries.

John H. Fitzgerald III was my mentor and taught me everything I know about corrosion, erosion and how they affect water piping systems. 

When metal piping is installed in plumbing systems, soil conditions and water content can affect the piping’s performance. This is especially true when different metals are connected, such as stainless steel and copper. 

Earlier this year, Congress passed the Infrastructure Investment and Jobs Act, a $1.2 trillion investment in our country’s declining infrastructure. 

The American Society of Sanitary Engineering’s (ASSE) 1070 Standard, Performance Requirements for Water Temperature Limiting Devices is an industry standard for a point-of-use or in-line temperature-actuated mixing valve with a maximum temperature limit feature.

In Part 1, published in this magazine’s February 2022 issue, we talked about why buildings lean, how this phenomenon affects plumbing systems and drain lines, and how low-flow fixtures compound this problem.
