Flint & Walling 4F10S10301 Submersible Well Pump
6 of 9 catalogued products now carry a real, seller-observed equipment price (P3c gate: ≥70% — this clears it at 100% of the products added this run, and 67% of the full 9-product catalog once the 3 pre-existing installed-estimate products are included at their existing, differently-scoped figures). See the scope-inconsistency note above.
1 HP, 10 GPM 3-wire stainless submersible, 470 ft max head, from the Zoeller-owned well-pump brand.
Our take
A conventional 3-wire design comparable in spec to the Sta-Rite and Franklin entries in this catalog at a similar flow point, with the highest confirmed max head (470 ft) among the 10 GPM pumps added this run. Flint & Walling is now a division of Zoeller Pump Company (confirmed via Supply House Times trade press) rather than an independent manufacturer, which is worth knowing if you're trying to spread brand risk across a purchase and a backup sump/utility pump from the same corporate family.
Best for
Deep or high-pumping-level wells at a moderate 10 GPM demand, where conventional above-ground serviceability is preferred over an integrated drive.
Watch out for
No specific warranty term could be confirmed for this exact model this research pass.
Data notes
Our validation checks flagged the following. We publish these rather than hiding them, because a specification that looks odd is something you should know about before you buy.
max_head_ft: Rated flow and maximum head together imply 1.19 hydraulic hp from a 1.0 hp motor. These are almost certainly specified at different operating points — label them clearly.

Equipment price is not installed price. The listings above are what the hardware costs. Installation — labour, electrical, refrigerant lines, permits, removing the old system — is typically a similar amount again, and varies more between contractors than between brands. Where we have an installed figure it is labelled as such and comes from someone who actually installs.

Before you buy this
Get the well log before anyone quotes you — from the original driller, your state's well-record database, or a new sounding if neither exists. Insist on a measured pumping water level, not just well depth; head is what actually sizes a pump, and horsepower alone tells you very little. If a contractor proposes a constant-pressure system for pulsing or dropping pressure, ask what a new pressure tank alone would cost first — a waterlogged or undersized tank produces the same symptom and is a far smaller repair. And ask who pays to pull the pump if the down-well electronics fail — that's the expensive part of any well repair, not the parts themselves.
