Plumbing deductions follow a pattern similar to other licensed trades: a service van, specialty tools, and parts inventory are the core categories. What distinguishes plumbing is the range of specialty equipment: sewer cameras ($5,000-$15,000), pipe locators, press tool systems (ProPress/MegaPress), and drain machines each represent meaningful investments that are fully Section 179 eligible. Parts inventory on the van is a tax consideration: fittings, valves, water heaters, and supply lines on the van at year-end are technically inventory. The de minimis safe harbor and small business exception handle this for most plumbers. Water heaters are the highest-cost single item carried, and whether to stock them or order per-job affects both cash flow and tax timing.

What does a full-year deduction breakdown look like?

Hypothetical example

Round numbers. A solo master plumber. Year 2 (van already depreciated). Revenue $200,000.

Deductions:

Category	Amount	% of Revenue
Parts and materials	$28,000	14.0%
Vehicle operating	$9,000	4.5%
Insurance (GL + auto + pollution)	$5,000	2.5%
Tool/equipment replacement	$2,000	1.0%
Marketing	$5,000	2.5%
Phone/software	$2,000	1.0%
Licensing/CE	$500	0.3%
Home office	$1,000	0.5%
Drain cleaning supplies	$800	0.4%
Total	$53,300	26.7%

Net profit: $146,700

Plumbing runs about 27% expenses for a solo service operator, nearly identical to HVAC and electrical. The licensed trades cluster around 25-28% ongoing expenses.

Water heater stocking strategy: Stocking 2-3 water heaters on the van costs $1,500-$3,000 in inventory.

Advantages:

Same-day installation (customer can’t shop around)
Premium pricing for immediate availability ($200-$400 premium)
2 same-day installs/month at $400 premium = $9,600/year in additional revenue

Disadvantage:

Capital tied up in inventory
Water heaters on van at December 31 = inventory (not deductible until installed)

Solution: install the stocked heaters before year-end. If 2 heaters are on the van on December 31 at $600 each, that’s $1,200 that can’t be deducted this year. For a plumber doing 15 installs/year, this timing issue is minor.

ProPress vs. soldering (cost and efficiency): ProPress fittings cost more than solder fittings:

1/2” copper tee: $0.50 (solder) vs. $5.00 (ProPress)
Per joint material cost: 10x higher with ProPress

But ProPress saves time:

Solder joint: 3-5 minutes (heat, flux, solder, cool, test)
ProPress joint: 15-30 seconds (insert, press)
On a job with 50 joints: 2.5 hours saved
At $100/hour billable: $250 in additional capacity

Annual ProPress fitting premium (200 joints/month x 12 months x $4.50 premium): $10,800 in higher material cost. Time saved (200 joints x 3 minutes x 12 months / 60): 120 hours/year. At $100/hr billable: $12,000 in additional billing capacity. Net benefit: $1,200/year PLUS the ability to do more jobs per day.

The ProPress tool itself ($2,500-$5,000) is Section 179 eligible. ROI: recovers cost within 6 months.
