For a basement home office, the plumbing bill is almost never the expensive part of a water problem. A 1990s South Jersey split level, a finished basement, one sump pump in the corner, and roughly $6,000 of tower, dock and monitors sitting on the only desk in the house that produces income. Price the boring version first: a supply line replacement plus a new sump pump and check valve, scheduled for a Tuesday morning. Example scenario, not a quote: one 1990s split level, one sump pit, one $6,000 desk. The desk only earns on the days it is switched on, and measured against that, a scheduled repair is the smaller number every time.
