Kitchen & Bath Faucet Replacement
| Material | Typical Qty | Notes |
|---|---|---|
| Faucet (kitchen or bath) | 1 | Match hole count to sink |
| Braided supply lines | 2 | 3/8" comp x 1/2" FIP typical |
| Plumber's putty or silicone | 1 | Check faucet instructions |
| Shut-off valves (1/4 turn) | 2 | Replace if gate valves |
| Teflon tape | 1 roll | Always have extra |
| Basin wrench | — | Tool, not material |
Pro tip: Always inspect the shut-off valves while you're under the sink. If they're old gate valves, upsell the replacement to quarter-turn ball valves. It's a 10-minute add-on that adds $40-80 to the ticket and prevents future emergency calls.
Water Heater Installation
| Material | Typical Qty | Notes |
|---|---|---|
| Tank water heater (40 or 50 gal) | 1 | Gas or electric |
| Flexible water connectors | 2 | Stainless braided |
| T&P relief valve | 1 | Usually included with heater |
| Discharge pipe (3/4" copper) | 1 pc | Run to drain or exterior |
| Gas flex connector | 1 | For gas units |
| Drip leg / sediment trap | 1 | Code requirement |
| Expansion tank | 1 | Required in closed systems |
| Dielectric unions | 2 | Prevent galvanic corrosion |
| Pipe dope / Teflon | 1 | For gas connections |
| Venting materials | Varies | B-vent or direct vent |
Pro tip: Check local code requirements for expansion tanks and seismic strapping. Missing these on an inspection means a costly return trip.
Toilet Installation
| Material | Typical Qty | Notes |
|---|---|---|
| Toilet (bowl + tank) | 1 | Elongated or round |
| Wax ring with flange | 1 | Or wax-free seal |
| Closet bolts (Johnny bolts) | 1 set | Usually 2 bolts |
