Ready to buy

Confirm the exact pump, package and installation

The retained reference is $323.25 current U.S. street reference. Confirm 115 V model 287 rather than 287HV or longer-cord suffixes and size the check valve and discharge to the curve. Commission every pump, float, check valve, alarm and notification path before relying on the installation.

System branch

High-flow serviceable cast-iron primary
Checked 6 days agoOur synthesis2 evidence items

Complete-purchase boundary

The 287's larger solids passage is a clog-resistance fact for suitable groundwater or effluent, not permission for sewage, and its eight-amp motor and high curve require circuit and cycle-volume checks
Checked 6 days agoOur synthesis4 evidence items

Head and flow boundary

The current 280-series performance curve places model 287 around 63 GPM at zero head, 55 GPM at 10 feet and 50 GPM at 15 feet with shutoff near 37 feet; select from the exact curve at total dynamic head
Checked 6 days agoOur synthesis2 evidence items

Basin fit and solids boundary

The vertical magnetic float and one-piece body need sufficient basin clearance and the pump passes up to 3/4-inch spherical solids; sewage, fibrous wipes and grinder duty remain excluded
Checked 6 days agoOur synthesis3 evidence items

Switch, check valve and discharge

The automatic magnetic vertical float turns on near 9-1/2 inches and off near 4 inches and needs clean, free travel; provide 1-1/2-inch discharge, full-flow check valve, union and required vent or relief detail
Checked 6 days agoOur synthesis3 evidence items

Power, battery and charger

The 1/2 HP 115 V motor is rated 8.0 A with 23 A locked-rotor current and a quick-connect grounded cord; no battery or charger is included
Checked 6 days agoOur synthesis3 evidence items

Runtime, alarm and connection

No backup runtime, alarm or remote monitoring is present; plan independent notification and backup around actual consequences
Checked 6 days agoOur synthesis3 evidence items

Maintenance, access and service

Water-test the switch, inspect bottom screen, cord seal, check valve and outlet and monitor cycle frequency; use qualified service and disconnect power before pit contact
Checked 6 days agoOur synthesis4 evidence items

Warranty and failure modes

The series carries three-year limited coverage; higher solids clearance does not eliminate float, cord, seal, blockage, recirculation, freeze, power-loss or overwhelming-flow failures
Checked 6 days agoOur synthesis3 evidence items

Shock, flood, mold, sewage and outcome boundary

This system cannot make energized or contaminated water safe, prevent groundwater or sewer backflow, remove mold, authorize confined-space entry, satisfy every electrical or plumbing code, permit or insurance requirement or guarantee flood prevention, runtime, notification, reliability, property protection, coverage or a claim outcome.

Current verdict

The high-flow Liberty primary

Liberty 287 fits a higher-flow pit where the vertical magnetic switch clears the basin and cord serviceability matters.

The 257's serviceable cord and magnetic float do not add backup, alarm or check valve, and its 1/2-inch solids label does not admit sewage to a residential groundwater sump

What changed

The product has a history

Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.

    Current exact pump, package, price and failure boundary retained

    287 was checked against exact manufacturer identity and manual, current U.S. price, hydraulic curve, basin and switch fit, discharge and check-valve path, power or battery system, alarm and connectivity, service, independent evidence and bounded owner or installer reports.

Owner experience

What repeats after the purchase

Owner and installer discussion returns to magnetic float fit, high-flow cycling, start load, cord replacement and professional selection rather than a universal reliability or flood result.

These are self-reported experiences across different basins, inflows, heads, pipe and check-valve layouts, circuits, batteries, chargers, alarms, networks, maintenance, installation quality, weather and service ages. They identify commissioning and service checks and do not establish standardized flow, runtime, notification delivery, reliability, failure rate, flood prevention, mold prevention, safety, code approval, insurability or claim outcomes.
SignalWhat owners reportOur readEvidence

magnetic float fit, high-flow cycling, start load, cord replacement and professional selection

Exact-model purchasers discuss compact switch fit, high flow, installer selection and replacement. The limited sample cannot prove durability or failure frequency.

Check locked-rotor margin, calculate cycle volume and commission the pump at the exterior outlet rather than equating 1/2 HP with adequate system capacity.

Manufacturer identity, exact current U.S. price, current manual or support path, independent editorial, laboratory or professional-market evidence and bounded exact-model owner or installer evidence were checked on August 18, 2026. This desk covers complete current or actively supported residential basement and crawlspace primary sump pumps, battery-backup sump systems and integrated primary-plus-backup packages. It excludes sewage, effluent-tank, grinder and utility pumps; standalone batteries, chargers, alarms and power converters; water-powered backups; commercial lift stations; unsupported or obsolete models; marketplace-only products; and cosmetic bundles or package padding. Pump flow must be read on the exact curve at total dynamic head, including vertical rise and pipe, fitting and check-valve loss. Zero-head flow and horsepower do not size a system. Basin diameter, depth, inlet elevation, usable cycle volume, switch travel, solids boundary, discharge diameter, check valve, union, air-lock relief, exterior termination and freeze or backflow exposure are installation facts. Primary, backup and high-water switches must move freely and be tested independently. Battery chemistry, group size, amp-hours, age, temperature, charger, cable, voltage sag, duty cycle and head control useful backup time; no runtime claim is a site promise. Audible, dry-contact, Wi-Fi, app and cloud alerts have different hardware, power, account, network, service, privacy and delivery boundaries. Keep receptacles, controllers, chargers and batteries dry and above possible water, use direct grounded connections and required GFCI and branch protection, isolate power before contact and use qualified electrical and plumbing work plus required permits and inspections. Never enter a sump, basin, crawlspace or other possible confined space without the applicable competent-person assessment and controls. Floodwater may contain sewage, chemicals, sharp objects and energized equipment. Do not touch water or pumps where electrical or contamination hazards may exist; use emergency, utility, remediation and public-health guidance. A sump system does not stop groundwater, sewer backup, plumbing failure, mold, backflow or contaminated flooding and does not replace drainage, grading, waterproofing, sewer protection, mold remediation, flood cleanup or a site-specific professional design. No product, curve, test, review, alarm, battery, warranty or installation guarantees flood prevention, runtime, notification, reliability, service life, mold prevention, property protection, code approval, permit acceptance, insurability, coverage or an insurance claim outcome.
