Give back to your profession and learn from each other. Members of ASSE belong to an organization represented by all disciplines of the plumbing and mechanical industries, forming a platform to receive, understand and solve industry problems relating to their businesses and professions.

The aims and purposes of ASSE International were proclaimed more than 100 years ago, but they continue to guide our organization’s activities today. Our mission is to continually improve the performance, reliability and safety of plumbing and mechanical systems to support our motto, “Prevention Rather Than Cure.” We encourage you to attend local chapter meetings, as well as our national Annual Meetings, get involved in chapter activities and apply for national committee work.

Whether it’s through planning or participating in local chapter activities and meetings, writing an article for our publications, mentoring a young member, or volunteering on a committee, your involvement is essential to ASSE International’s success.

Why did our members become members?

“ASSE is a leader in the cross-connection control industry and I wanted to be a part of the organization.”

“To maintain a relationship with a cross-section of people in the piping industry and to advance my career.”

“My company partners and relies on ASSE to uphold standards and certification integrity.”

“To become more familiar with my industry, keep up with the latest technology, ideas and discussions, and to be part of keeping our industry safe.”

“The main reason was to stay in front of code changes and new technology, and to share this information with my co-workers.”

ASSE Sustaining Membership for product manufacturers, institutes, societies, associations, and organizations

In addition to the ASSE benefits listed above, ASSE Sustaining Members also enjoy the privileges that come with IAPMO membership, including:
