Property managers and HOA boards in Addison spend a lot of money on reactive plumbing calls — mostly because the same problems recur. A structured maintenance plan trades a predictable monthly cost for far fewer emergencies.
Here is what a real plan looks like.
The 4 recurring items every multi-family plan should include
1. Quarterly drain inspection
Cable or camera the main-line stacks quarterly. Catches root intrusion, developing bellies, and grease loading before they back up.
2. Semi-annual water heater inspection
For central boilers: check T&P valves, expansion tanks, gas pressure, and combustion. For unit-by-unit: sample inspections rotating through 25% of units per quarter.
3. Annual backflow test + certification
Required by City of Addison for irrigation systems, mechanical rooms, and any multi-family with a common water system. We test, certify, and submit to the city.
4. Grease trap service (restaurant/mixed-use)
Every 90 days pump + every 6 months line jetting for tenants with commercial kitchens. Includes manifest documentation.
The 3 optional items worth adding
- Winterization prep (October) — bib insulation, exterior-line insulation, common-area shutoff testing
- Water heater flushing (unit-by-unit) — rotate through units annually
- Preventive sewer camera (main line) — every 2 years to catch developing issues
Typical plan structure
For a 100-unit Addison multifamily, a plan usually structures as:
- Fixed monthly fee for scheduled inspections and rapid-response prioritization
- Per-unit rate for water heater work
- Time-and-materials for anything beyond scope
- Waived after-hours emergency premium for plan holders
What it should NOT include
- Fixture repairs inside individual units (unless a per-unit rate is agreed)
- Restoration / drying work (separate specialty)
- Owner-caused damage (clogs from misuse etc.)
The reactive vs. planned math
For a typical Addison multi-family, reactive-only plumbing runs 3–5x what a planned maintenance contract costs — because emergency calls come at overtime rates and problems compound.

Belt Line Plumbing expert insight
This guide reflects what our licensed Texas RMP plumbers see on real commercial calls across Addison, Farmers Branch, Carrollton, and the greater Dallas North Tollway corridor. Belt Line Plumbing Co. has served the Addison area since 2007, with 412+ five-star reviews from north Dallas homeowners, property managers, and Belt Line Restaurant Row operators.
Local factors that affect the advice above: North Texas expansive clay soil drives most residential slab and sewer failures; Dallas Water Utilities supply water at 8–11 grains of hardness per gallon shortens every water heater and tankless system without a softener; and the February 2021 Winter Storm Uri freeze exposed attic supply lines across almost every 1970s–2000s Addison home. If your situation includes any of these local realities, factor them in before deciding between repair, replacement, or a preventive upgrade.
