How do operators decide when to retire an older porta potty from the fleet?

Question

I've been running my fleet for over a decade now, and I still see some competitors' units on job sites that look beat to hell, cracks, faded plastic, doors that don't latch right. We all start with used units, but at some point, you have to decide when to pull one for good. My own criteria include structural integrity (no cracks in the tank or base), door and latch function, and overall cleanliness after service. If a unit needs more than minor repairs after every rental, it's costing me time and money. But I'm curious: what specific thresholds do other operators use? Do you retire based on age, repair frequency, customer complaints, or something else? How do you handle the disposal of old units?

Operators retire older portable toilets based on repair costs exceeding replacement value, persistent structural damage, and customer feedback. A [standard unit](https://portapotty.forum/glossary/standard-unit/) with cracks in the tank or base is an immediate retirement candidate because it risks leaks and violates health codes. Doors that won't latch or chronic odor issues after servicing also signal it's time to pull the unit. Age alone isn't the deciding factor; I've seen well-maintained units last 15 years, while others fail in 5 due to harsh use or poor care. The tipping point is when repairs become more frequent than rentals, eating into profits and technician time. For disposal, most operators drain and clean the unit, then salvage reusable parts like doors or vents before sending the plastic shell to a recycler. Landfilling is a last resort, but some municipalities restrict it due to the bulk.
