Ready to buy
Confirm the exact pump, package and installation
The retained reference is $567.36 current U.S. retail reference. Confirm the upgraded N model, battery and check-valve exclusions and return terms, then measure the basin at the switch and inlet elevations before ordering. Commission every pump, float, check valve, alarm and notification path before relying on the installation.

Complete-purchase boundary
WSS30VN needs a wide 15-inch tapered or 16-inch straight basin, a separately purchased 75 Ah battery and an installer-supplied check valve; its audible alarm has no remote connection and both pumps share one discharge assembly
Checked 6 days agoOur synthesis4 evidence items
Head and flow boundary
The AC CDU800 side is rated 5,100 GPH at zero and 3,840 at 10 feet; the 12 V side is rated 2,700 at zero and 1,500 GPH at 10 feet, so outage capacity must be compared at the actual head
Checked 6 days agoOur synthesis2 evidence items
Basin fit and solids boundary
Wayne specifies at least a 15-inch tapered or 16-inch non-tapered pit and an assembly width near 14.875 inches; both pumps are groundwater sump pumps rather than sewage or debris pumps
Checked 6 days agoOur synthesis3 evidence items
Switch, check valve and discharge
The AC vertical float and separate backup reed float require free movement; the preassembled pumps share a 1-1/2-inch discharge and require an installer-supplied check valve above the junction, leaving the valve and outlet as common failure points
Checked 6 days agoOur synthesis3 evidence items
Power, battery and charger
The primary uses 120 V and the backup uses one separately purchased supported 12 V deep-cycle battery, with Wayne recommending WSB1275 75 Ah; charger status does not replace periodic capacity testing
Checked 6 days agoOur synthesis3 evidence items
Runtime, alarm and connection
Wayne's hours-of-protection language depends on battery, head and cycling; the controller sounds an audible alarm when backup runs and has no built-in Wi-Fi or cloud notification
Checked 6 days agoOur synthesis3 evidence items
Maintenance, access and service
Water-test both switches, remove AC power under observation, load-test battery, inspect charger lights, the shared check valve and exterior outlet and preserve room to pull the whole assembly for component replacement
Checked 6 days agoOur synthesis4 evidence items
Warranty and failure modes
Current warranty documentation gives three-year limited coverage for WSS30Vn; dead battery, charger or reed-switch fault, AC switch fault, missing or failed check valve, blocked shared discharge, freeze, overwhelming inflow and unheard local alarm remain
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 tested value combination
WSS30VN is the strongest mainstream value when the basin accepts its broad footprint and local-only alarm is adequate.

Tradeoff
The drop-in assembly still requires a compatible basin, separate battery, code-compliant receptacle and discharge; one preassembled check valve and pipe do not remove shared-path or freeze risks
CITS-50 is preassembled but the battery and BW-WiFi2 remote module are separate; its shared discharge, basin fit and controller generation must be confirmed
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.

Owner experience
What repeats after the purchase
Owner and installer discussion returns to wide-basin fit, drop-in plumbing, check-valve addition, battery choice, local alarm and outage testing 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
wide-basin fit, drop-in plumbing, check-valve addition, battery choice, local alarm and outage testing
Build a cardboard footprint at the inlet and float heights, add the specified check valve and then prove both pump paths and the local alarm with the chosen battery and real discharge.

Mold, moisture and home cleanup boundaryU.S. Environmental Protection Agency · specification
EPA guidance centers moisture-source correction, prompt drying and appropriate remediation. A sump pump does not by itself stop leaks, dry materials or remediate mold.
Flood cleanup electrical and contamination hazardsU.S. Centers for Disease Control and Prevention · specification
Flood cleanup can involve electrical shock, sewage and chemical contamination, mold, unstable materials and injury hazards that require appropriate utilities, protective equipment and trained help.
Confined-space hazard frameworkU.S. Occupational Safety and Health Administration · specification
Pits and restricted spaces can contain hazardous atmospheres, engulfment or difficult rescue conditions. Entry requires an applicable assessment and controls rather than an assumption that a residential space is safe.
Flood insurance policy boundaryNational Flood Insurance Program · specification
Flood insurance coverage, exclusions, documentation and claim outcomes are policy- and event-specific. Equipment ownership or an alarm does not guarantee coverage, insurability or payment.

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.
