History of
CP Conway Plumbing


Back in 1929, Charles Patrick (C. P.) Conway graduated from Boy’s Technical School in Milwaukee with a plumbing diploma. It was the first step toward fulfilling his dream of owning a business: C. P. Conway Plumbing, Inc.


In August of 1960, some 30 years after earning his plumbing diploma, C. P. realized his longtime dream and incorporated a business: C. P. Conway Plumbing, Inc. at 5725 W. Vliet St. In July of 1968, the company moved to its present site at 1231 S. 62nd St. in West Allis.


C.P. Conway Plumbing was a one-man operation, so there wasn’t always enough work for all three sons. So Chuck and Harry eventually left for larger companies that offered steadier work. Richard the third son, stayed on and eventually bought the business in 1976.


Rick, Richards oldest son, graduated from college in 1993 with a degree in environmental science, but joined the company due to a shortage of jobs in his field. After working as an apprentice and then a journeyman plumber, Rick obtained his master plumber’s license, which paved the way to buying the company.


In 2005, Richard sold the business to Rick who owns and runs CP Conway Plumbing Inc. to this day.
