What is a Responsible Master Plumber (RMP) in Texas?
A Responsible Master Plumber (RMP) is a Master Plumber who has registered with TSBPE to be responsible for the plumbing work of a company. A business must operate under an RMP to pull plumbing permits, and the RMP is verifiable on the TSBPE license search.
