[Request Service](https://legacyplumbingmo.com/request-service) [636-978-0120](tel:+16369780120) ## Common Plumbing Needs - Medical gas piping, testing and certification - Dental vacuum, air and equipment hookups - Thermostatic mixing valves and water temperature control - Tenant finish for medical and dental suites - Scheduled maintenance with minimal patient disruption ## Planning Plumbing for Healthcare Healthcare plumbing brings domestic water, sanitary drainage, equipment connections and medical gas into the same project. For a dental suite, rough-in must coordinate with operatories, sterilization areas, lab support and the owner's equipment vendors. In an existing medical building, review the affected zones and planned shutdowns before work starts. Our tenant build-out and preconstruction services cover existing-condition review, fixture coordination and construction planning rather than treating the plumbing as an isolated trade. ## Services for Your Building ### [Medical Gas](https://legacyplumbingmo.com/services/medical-gas) Legacy Plumbing's medical gas installers are ASSE 6010 certified brazers who install, purge and document every system to NFPA 99 before an independent ASSE 6030 verifier walks the job. As a medical gas installer for healthcare facilities across the St. Louis metro, we install and repair med gas piping for dental offices, clinics and surgery centers. ### [Tenant Build-Out](https://legacyplumbingmo.com/commercial/tenant-finish) Tenant finish plumbing connects a commercial shell or existing suite to the fixtures and equipment needed by its new tenant. Legacy Plumbing handles this tenant build-out plumbing, also called tenant improvement plumbing, from existing-system review through rough-in, fixture installation and permit coordination across St. Louis, St. Charles and Jefferson County. General contractors, property managers and tenants hire us for this work, and our crews are UA Local 562 union plumbers. ### [Commercial Water Heaters](https://legacyplumbingmo.com/facility-services/commercial-water-heaters) Gas and electric commercial tanks, storage tanks, and multi-unit banks sized to peak demand. Rack-mounted condensing tankless installs with cascade controls, proper venting, and condensate neutralization. ### [Retrofits & ADA Upgrades](https://legacyplumbingmo.com/facility-services/ada-retrofits) Water closets, lavatories, and urinals moved to compliant clearances and mounting heights with new carriers and rough-in. Insulated supply and drain wraps, lever or sensor faucets, and compliant operating force on every accessible fixture. ## Code, Compliance & Maintenance Medical gas work is governed by NFPA 99. Legacy Plumbing's ASSE 6010 brazers install medical gas copper under nitrogen purge, with pressure, cross-connection and purity testing followed by independent ASSE 6030 verification. Test records, brazer certifications and as-built drawings become part of the facility's documentation. Domestic water systems also need appropriate backflow protection and temperature control; our water heater service includes thermostatic mixing valves and scald protection. Legacy Plumbing has its own Missouri-certified, St. Louis County-licensed backflow testers. ADA retrofits address accessible fixtures, clearances and controls when restrooms are renovated.
