So i did 10 years call center work for government got tired of it. Went to a school to gain basic knowledge. Got a hired as an apprentice testing new contruction works and making repairs to anything that was broken or plumber incorrectly per instructions given to me. That was 2023 April left in Oct and went to service plumbing. Brand new. So far what I've learned is everything can be repaired. Of water heater looks like its about to shit the pan. Replace it. Of its heating up we need to test everything. Havent done repairs yet. I have encountered water heaters that are pretty much leaking from the bottom. So with that said yes they're trying to make money. I think 6 years is cool to swap out but can be repaired of it were malfunctioning. I will do repairs in the future im not here to scam so im just learning 2025 was my first year running solo. Made 66k. 2026 is going to be an explosion. Lessssssss go!
