Quick answers

- Agree who pulls which permits.
- Schedule overlap or clear handoff times.
When to use this guide
You’re replacing a heater in the next 1–3 weeks and want a clean dual-trade plan.
Checklist before you buy equipment
Fuel type, venting path, drain pan/T&P route, electrical disconnect location, breaker size, and whether the panel can support the load. Photograph the existing nameplate and panel labels for both trades.
Day-of handoff
Power locked out before plumbing demo on electric units. After set and water fill, electrician completes final connections; plumber verifies water-tight operation.
Failure modes to avoid
Plumbing install first, electrical “later”
Later often means days without hot water and frantic change orders.
