The picks

The exact models the calculators name

Run the numbers first — the Water & Rain-Catchment Calculator filters these to your result. Street-price bands, checked recently, not list prices.

  • Bushman 4" first-flush diverter kit — dumps the dirty first roof-wash before it reaches the tank — the cheapest water-quality upgrade there is. $30–60 · View
  • Bushman Maelstrom filter — 180-micron pre-filter rated to 158 gpm at 96% catchment efficiency. $300–450 · View
  • Norwesco poly cistern — the standard above-ground tank — budget roughly $0.50–1.00 per gallon as sizes grow (500 gal shown). $400+ · View
  • SoftStartUp — clamps your existing 240V pump's start surge so a mid-size inverter can carry it — often the whole fix. $300–340 · View
  • Grundfos SQFlex 6 SQF-2 — 30–300VDC solar-direct submersible with dry-run and overload protection built in. $2,000+
  • Anker SOLIX F3800 — the 240V battery source with the surge headroom this calculator sizes for. $1,999–2,400 · View
  • Zoeller Aquanot 508 — 40 GPM standalone backup that bolts beside the primary you already own. $430–480 · View
  • Wayne ESP25 — the budget backup — up to 10,000 gallons on one 75Ah charge, cast-iron housing. $320–360 · View
  • Deep-cycle AGM, group 27/31 — the consumable every backup pump runs on — plan on replacing it every 3–5 years. $180–260
