[Request Service](https://legacyplumbingmo.com/request-service) [636-978-0120](tel:+16369780120) ## Common Plumbing Needs - Grease interceptor installation and repair - High-demand water heaters and booster heaters - Gas piping for ranges, fryers and ovens - Floor drains and indirect waste for equipment - Backflow devices for ice machines and beverage lines ## Planning Plumbing for Restaurants & Food Service Restaurant plumbing combines grease waste, high hot-water demand, gas equipment, floor drains and indirect waste connections. Legacy Plumbing installs and repairs kitchen plumbing for restaurants and food-service operators across the St. Louis metro. A new kitchen or tenant build-out should coordinate the fixture layout and equipment connections with the existing water, waste and gas systems. Service planning should identify whether the issue is inside the trap, in a downstream line or at the water heating equipment rather than treating every symptom as the same repair. For scheduled interceptor service, see our [grease trap cleaning and maintenance](https://legacyplumbingmo.com/facility-services/grease-trap-cleaning) . ## Services for Your Building ### [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. ### [Service & Repair](https://legacyplumbingmo.com/services/service-repair) Legacy Plumbing handles commercial plumbing repairs, drains and maintenance across the St. Louis metro with union plumbers. For an active leak, sewage backup or loss of essential hot water, protect people first and call with the affected system and shutoff status. The office must confirm scheduling. ### [Grease Trap & Interceptor Service](https://legacyplumbingmo.com/facility-services/grease-trap-cleaning) Under-sink and floor-mounted trap pumping, scraping, and reassembly with new gaskets where needed. In-ground grease interceptor pumping, wall and baffle cleaning, and inlet/outlet tee inspection. ### [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. ### [Sewer Camera Inspection](https://legacyplumbingmo.com/facility-services/sewer-camera-inspection) Pre-purchase inspection of laterals and underslab lines so sewer condition is priced into the deal. Documenting line condition between tenants so responsibility for damage is clear. ## Code, Compliance & Maintenance Grease trap and interceptor service includes pumping, baffle and tee inspection, line cleaning, repairs and dated service records for MSD and health-department review. MSD directs food service facilities to clean grease interceptors at regular intervals and when they reach 60 percent of capacity. Maintenance frequency is set from the actual grease and solids load. Backflow protection also applies to connections such as ice machines and beverage lines. Legacy Plumbing has its own Missouri-certified, St. Louis County-licensed backflow testers. Water heating work must account for peak demand, appropriate venting, mixing valves and scald protection. Camera inspection can document roots, offsets, cracks or buildup in a problem drain before a repair scope is committed.
