Wayne Water Systems · CDU800
Ready to buy
The retained reference is $158.78 current U.S. retail reference. Confirm CDU800 rather than steel or different-switch relatives and add the exact valve, union, alarm and backup needed by the installation. Commission every pump, float, check valve, alarm and notification path before relying on the installation.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Confirm CDU800 rather than steel or different-switch relatives and add the exact valve, union, alarm and backup needed by the installation. Confirm exact current stock, seller authorization, tax, delivery, battery, valves, pipe, alarm, labor, permits and return terms before paying.
CDU800 is the lower-cost high-flow choice when 3,840 GPH at 10 feet fits the calculated duty and the fixed switch cycle will not expose the inlet or cause rapid cycling.

These are not generic competitors. Each one represents a different way to buy into the same market.

What changed
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.
CDU800 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.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and installer discussion returns to fixed-cycle fit, noise, storm cycling, float behavior, corrosion and replacement dimensions 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.Exact-model owners discuss noise, rapid storm cycling, float operation, replacement fit and corrosion. Self-selected reports do not establish cycle life or reliability.
Measure the real pit cycle volume and head, then observe repeated starts and check-valve closure before deciding that high catalog flow solves the system.

Wayne Water Systems identifies exact model CDU800 as a top-suction primary with fixed vertical switch, strong medium-head flow and a compact 11-inch basin claim.

Wayne publishes 5,100 GPH at zero head, 4,500 at 5 feet, 3,840 at 10 feet, 3,060 at 15 feet and 2,040 at 20 feet; size from total dynamic head, not the zero-head headline Wayne states an 11-inch-or-larger basin and top suction intended to reduce air lock and debris intake; no sewage or grinder solids capability is admitted and sediment still needs removal The integral vertical float turns on near 9 inches and off near 4 inches and needs wall, cord and inlet clearance; provide a 1-1/2-inch NPT discharge, union and separately purchased check valve
The 120 V PSC oil-filled motor uses a grounded GFCI-protected direct receptacle and suitable circuit; there is no battery, charger or outage supply CDU800 has no battery runtime, alarm or connectivity, so a separate high-water alarm and independent backup decision remain Run multiple water cycles, inspect top suction, float guard, check valve and freeze-safe outlet and keep removal clearance; disconnect power before pit work The exact model has three-year limited coverage; float hang-up, short cycling, seal or motor fault, loss of power, check-valve leak, clogged or frozen discharge and excess inflow remain possible
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 can involve electrical shock, sewage and chemical contamination, mold, unstable materials and injury hazards that require appropriate utilities, protective equipment and trained help.
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 coverage, exclusions, documentation and claim outcomes are policy- and event-specific. Equipment ownership or an alarm does not guarantee coverage, insurability or payment.
Independent current comparison preserves the exact 3,840 GPH at 10-foot point, vertical switch, 1-1/2-inch discharge and material tradeoff instead of ranking by horsepower alone.
Exact-model owners discuss noise, rapid storm cycling, float operation, replacement fit and corrosion. Self-selected reports do not establish cycle life or reliability.

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.
