Evaluate Repairability and Conclude

What happens here

The presenter continues to examine the severely corroded cartridge, noting its deteriorated state. He questions whether it could have been cleaned but then concludes that after trying to reassemble it earlier, it's not worth further effort. Given the extensive internal damage and debris, he determines the valve is beyond repair and decides to scrap the entire brass valve, rather than attempt a cartridge replacement, as it would be more practical and cost-effective to replace the entire unit. This emphasizes that while sometimes cartridges can be cleaned or replaced, severe damage necessitates full component replacement.
