Plumbing Service Agreement Pricing Calculator
Prices an annual residential plumbing maintenance agreement covering water heater flush, PRV check, shut-off valve inspection, and anode rod inspection — the standard recurring-revenue package for plumbing contractors. Builds the recommended annual price from labor cost per visit (technician loaded rate × visit time), parts and consumables, overhead per visit, and a target gross margin applied as a divisor. Compares the result against a competitor benchmark. Benchmarked against PHCC (Plumbing-Heating-Cooling Contractors) residential maintenance agreement pricing surveys.

How this calculator works
This calculator prices an annual residential plumbing maintenance agreement — the recurring-revenue backbone of a growing plumbing operation. It builds the recommended annual price from labor cost per visit (technician loaded rate multiplied by visit time in hours, scaled for multi-system agreements), parts and consumables per visit, overhead per visit, and a target gross margin applied as a divisor. The recommended price is then compared against a competitor benchmark to assess market position.
What a standard plumbing maintenance agreement includes
A standard single-visit residential plumbing maintenance agreement typically covers: water heater sediment flush and anode rod inspection, pressure-reducing valve check and pressure reading, shut-off valve inspection (main, toilet, under-sink), expansion tank inspection on closed systems, and a visual survey of exposed supply lines, p-traps, and drain flanges. The visit typically runs 30-60 minutes for a single-family home with one water heater and one PRV.
The lifetime value logic behind maintenance agreements
The direct margin on a maintenance agreement visit may be modest — $50 to $100 of gross profit on a $149-$199 annual agreement is not a revenue transformation. The financial logic is in the lifetime value multiplier. Agreement customers call their existing plumber for 100% of demand service needs; non-agreement customers call around 60-70% of the time. When the agreement visit identifies an aging water heater, the agreement customer converts to a replacement at 3-5 times the rate of a non-agreement customer. Agreement customers generate 1.5-2 times the number of word-of-mouth referrals. PHCC cost-of-doing-business surveys consistently show that operations with active agreement programs generate 15-30% higher annual revenue per technician than otherwise-comparable operations without programs.

A standard single-visit residential plumbing maintenance agreement typically covers: (1) water heater flush — sediment flush on tank heaters, anode rod inspection; (2) PRV check — measure supply pressure, verify PRV setpoint and function; (3) shut-off valve inspection — main house shut-off, toilet shut-offs, under-sink valves — for corrosion, ease of operation, and seating condition; (4) expansion tank inspection on closed systems; and (5) visual inspection of exposed supply lines, p-traps, and drain flanges for signs of active or pending leaks. Some operations add a drain treatment (enzyme or bio) on the kitchen drain as a consumable-cost add-on. The visit typically runs 30-60 minutes for a single-family home with one water heater and one PRV.
