Why Consumables & Disposal Wreck Plumbing Profits

A $1,850 tankless water heater seems straightforward, but solder, flux, gas, copper fittings, venting adapters, and gas piping easily add another 8–12% ($150–$200). If you also pay $60 to haul away the old tank and $60 for the city plumbing permit without adding them to your cost basis, your profit drops by more than $300.

Job Profit Kit separates materials, consumables, loaded labor burden, and flat job overhead so you always bid with complete financial clarity.
