3 Laws of Plumbing Mug
Trade school didn’t prepare you for this level of wisdom.
The 3 Laws of Plumbing Mug lays down the sacred rules of the industry, no apprenticeship required:
💩 Runs downhill.
💰 Payday is Friday.
🚫 Don’t eat with your… yeah. You get it.
It’s crude. It’s accurate. It’s basically a TAFE certificate in ceramic form.
Built for tradies, drain whisperers, pipe legends, and anyone who understands that gravity and poor life choices are undefeated. This mug belongs in the smoko shed, or front and centre in the workshop where delicate ears fear to tread.
Available in 11oz for quick site coffees and 15oz for “this job’s bigger than quoted” mornings. Glossy white ceramic. Dishwasher and microwave safe. Because plumbing is messy enough.
Gift it to your favourite plumber. Or keep it as a daily reminder that some laws are universal. Gravity. Money. Hygiene. In that order.
