Then it sounds like HVAC/Refrigeration it the trade for you. It's kind of funny because we tend to get all the people who dropped other trades for various reasons. I work with ex plumbers who didn't want to deal with shit, I work with journeyman electricians who didn't want to spend 8 years becomming a master electrician, I work with ex building automation guys who got tired of trying to automate busted equipment. A lot of my coworkers started in other trades, went "This fucking sucks" and switched to HVAC-R.

It's not all just poopoo peepee stuff. A lot of plumbers do mechanical work in commercial buildings, boiler retrofits, repiping, construction. I'm in commercial HVAC and work with a bunch of plumbers whose skills and scope of work have great overlap with mine. I've also helped them out doing boiler retros/repipes. We offer similar services, subcontracting each other to our own customers, just they do more of the gas fired work and fix leaks in heating loops and I do the AC/Refrigeration stuff

There’s other hand-craft trades that don’t involve sewage. If you get into the commercial space, there’s a good chance you’d deal with it a lot less if at all since they would need a specialist for biohazards.

You haven't lived the Great Australian Dream?

Plumbing isn't exactly rocket science. And with some infra companies you don't have to deal with any nasty parts.
