Three Generations of Plumbers

In 1971 the first generation of Kowality Plumbing began a legacy of plumbing craftsmanship. Jerry Kowalczyk Sr. (Steve Jr’s grandfather) founded Aquarena Gas in Mesa, Arizona along with his two sons; Steve Sr. and Jerry Jr.

Aquarena provided plumbing and gas services throughout the Valley.

Having learned his skills in the days of coal fired furnaces and pipe joining methods such as lead and okum, Jerry Sr. instilled core values and quality workmanship that continues through Kowality Plumbing today. Our mission is to deliver value to our customers by providing high quality service, with integrity, in a professional manner, at a fair price.

Steve Kowalczyk Jr., owner of Kowality Plumbing, literally grew up in the family business learning everything about the plumbing industry from his grandfather and father. In the early days, this family company focused primarily on gas line installations and repairs and evolved into an integrity-based full service commercial and residential plumbing company.

Steve fondly recalls one of the last “family” projects he worked on with both his dad and grandfather prior to their passing was building the new Show Low High School from the ground up in early 2000, along with his uncles and cousins.
