How tipping works in this job
Plumbing tips are gratitude for averted disaster: a burst pipe stopped, a blockage cleared before a holiday, a callout answered at 2am. That makes them concentrated in emergency work and almost absent from scheduled installs. Cash at the door is the norm, and on a two-person job it is usually split on the spot.
The regulations say: Assemble, install, alter, and repair pipelines or pipe systems that carry water, steam, air, or other liquids or gases. May install heating and cooling equipment and mechanical control systems. Examples given: Plumber, pipefitter, steamfitter, sprinkler installer.
The thing most likely to disqualify your tips
The emergency call-out premium is a price, not a tip. Doubling the rate for a Sunday night is your company charging more for unsocial hours — the customer had no choice about it once they called. Only what they added afterwards, of their own accord, qualifies.

How this applies to home plumbers
Plumbing gratuities are gratitude for a disaster that did not happen. A burst supply line stopped before it reached the floor below, a blocked main cleared the morning before a family arrives for a holiday, a water heater replaced the same day rather than the next week — these produce cash, reliably and often generously, from homeowners who have just watched a problem they could not solve get solved. Routine installs and scheduled fixture replacements produce almost nothing by comparison.
Because so much of that work happens outside ordinary hours, the emergency premium is the single most common confusion in this trade. A doubled rate for a two-in-the-morning callout is a price your company set for coming out at two in the morning. The customer accepted it as a condition of getting help; they did not choose it as a gesture. Every line on the invoice — labour, parts, the callout, the camera survey, the excavation — is revenue. What the homeowner pressed into your hand afterwards is not.
Two-person jobs are the norm on anything substantial, and cash handed over at the door is usually split on the spot. That split is what governs: your qualifying figure is your half, or your share if the division is uneven, not the amount that was handed over.
The code covers pipefitters, steamfitters and sprinkler installers alongside general plumbing, but the residential framing still applies. Fire sprinkler work in a commercial building, process pipework in a plant and steam systems in an institution are outside the occupation as described, even though the trade skills are identical and the same person may do all of it in a given month.
