That little tank is the least of your worries honestly. What matters is what the GROUND does under your house after years of that drip line. A leak that goes unnoticed for a decade can wash out the soil underneath your slab and that becomes a foundation repair that costs more than your whole kitchen redo. The permit guys have their codes but they don't test what the dirt is doing. My advice is to check your neighbor's water bill against yours. If theirs is way lower with the same size household, that drip line is working TOO well and it's going somewhere it shouldn't.

Losing a four figure contract because a laptop died sounds like bad planning more than bad luck. A dead external drive and no backup at a coffee shop means he ignored every warning sign for years. Most remote workers get by fine with a cloud plan and a phone that can hotspot in a pinch. Overhauling your whole setup over one horror story is like buying a bunker because your neighbor's house got struck by lightning. Maybe just test your backups once a month and move on.
