Laundry boiler maintenance is a necessarily uncompromising job. Imagine a pressure vessel on a Melbourne high street, a back room setting that's always loaded with steam. On the outside, the laundromat operates like any other business. The staff do their job, clothes are cleaned, and the hiss of steam fades into the background. Only this is a potentially dangerous site. The boiler, pressurized as it is, won't last long without hourly maintenance.
