Where it may fit

  • Comparing manufacturer-documented crawl-space, basement options for a matching installation.

Before you buy

  • Confirm exact SKU and generation against the current installation manual.
  • Check access dimensions, operating conditions and the complete drain route before purchase.

The tradeoffs

  • The PDF scalar dimension table has an axis-label error; use its drawing for cabinet height and confirm the exact horizontal footprint. The body contains stray pump wording although product drainage is gravity.
