Franklin Electric FPS 4400 Tri-Seal 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, 25 GPM thermoplastic-body submersible with a 205 ft max head — the highest flow rating and the only thermoplastic-body pump in this catalog.
Our take
Same manufacturer as the existing franklin-20fv1s4 in this catalog, but a completely different design point: a thermoplastic body instead of stainless steel, and a pump curve tuned for high flow (25 GPM, the highest in this catalog) at the cost of head (205 ft, the lowest). This project also found Franklin Electric's own official submersible-motor warranty document, which states 1 year from installation or 2 years from manufacture, whichever comes first — notably shorter than the flat 3-year figure this catalog's existing franklin-20fv1s4 carries; that existing figure was not independently re-verified this pass and may be worth a second look.
Best for
Shallow-to-moderate wells with high simultaneous demand — irrigation-adjacent households, or larger homes with many fixtures, where 205 ft of head is genuinely sufficient.
Watch out for
Do not pair this with a well whose pumping level approaches or exceeds 200 ft — its head ceiling is the lowest in this catalog. Thermoplastic body construction; confirm impeller/diffuser material separately if corrosion resistance in aggressive water is a concern.
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 1.29 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.
What owners and installers report
Collected from trade forums, owner communities and video reviews. Every report links to the original. We synthesise and quote briefly — we don't republish other people's writing.
Every report below traces back to a single source. The sections are broken out by topic because that's how they read, but treat this as one data point, not independent corroboration across topics — a second source agreeing (or disagreeing) would change that.
Warranty and manufacturer support
What actually happens when owners make a claim.
Franklin Electric's own official limited-warranty document states coverage of 1 year from date of installation OR 2 years from date of manufacture, whichever comes first, for its submersible motors — notably shorter than the flat 3-year warranty_parts_yr figure this catalog's existing franklin-20fv1s4 entry currently carries at 0.6 confidence (sourced only as generic 'mfr_docs', not this specific document). Flagged here as a real finding for the integrator to reconcile, not silently corrected on the existing product.

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.
