VEVOR 900 W macerator pump review

A 900 W macerator pump with 48 GPM flow, 40 ft of lift, a startup delay circuit and four inlets.

What the maker puts in writing

“The upgraded delay feature reduces the frequency of pump startups, resulting in quieter operation and extending the macerator pump’s overall service life”
“With a 1.2 HP/900W motor and 48 GPM/180 LPM flow rate… Its 40 ft/12 m lift capability efficiently drains wastewater, regardless of your space layout”
“Equipped with an IPX8 waterproof, oil-filled copper motor, this macerator sewerage pump handles wastewater up to 75℃/167℉ from washing machines and dishwashers”
“4 water inlets (1 x 89 mm (0.04 × 3.50 in) and 3 x 40 mm (0.12 × 1.57 in)), easily connecting to sinks, showers, and bathtubs”
“A specially designed silver ion water tank has an inhibition rate of up to 99% and effectively prevents the generation of odors”

The delay circuit is the cleverest thing on this shelf

Everything else here competes on hydraulics. This competes on switching, which is what actually wears a macerator out.

A macerator starts when the float in its tank rises and stops when it falls. With tight switching it fires for two seconds every time somebody rinses a cup — dozens of times a day, each start pulling the inrush current of a 1.2 horsepower motor.

Motor starts kill pumps far faster than running hours do. It is why a pump that runs for ten minutes outlives one that runs for ten seconds sixty times.

A delay circuit waits before starting and runs a little longer, so the count falls sharply. VEVOR gives both results: quieter operation and extending the macerator pump’s overall service life.

No other listing on this shelf mentions the switching at all.

Forty feet, with a caution attached

This is the highest lift figure on the shelf, and it should be read carefully against the Saniflo’s fifteen.

Maximum head is measured where the flow falls to nothing. It tells you where a pump stops working, not where it works well.

Saniflo publishes 15 feet vertically or 150 feet horizontally — a working duty with the trade-off stated — and carries CSA and IAPMO certification behind it.

VEVOR publishes 40 feet and no horizontal figure at all.

Both may be truthful measurements of different things. What is reliable is the ratio the two listings that publish both numbers agree on: one foot of rise costs about ten feet of run. On a forty-foot basement route to the stack, four feet of your lift has gone before anything climbs.

Ask VEVOR for the horizontal figure.

Everything the 500 W has, with more of it

Eighty-nine millimeters and three forty-millimeter inlets — the toilet horn and three waste connections, the figures that decide whether existing pipework connects. Two pumps on this shelf publish them and both are VEVORs.

One hundred and sixty-seven degrees Fahrenheit, which is what allows a washing machine or dishwasher to discharge into it. Four of the six pumps here publish no temperature.

IPX8 oil-filled copper motor — a continuous-immersion rating, with the motor cavity flooded in oil to exclude water and carry heat out of the windings.

Which VEVOR, though

All three are internally consistent, so the choice is about the pipe:

900 W — 47.6 gpm (180 LPM) at 39 ft (12 m) — $129.90. The strongest climb. 800 W — 52.8 gpm (200 LPM) at 33 ft (10 m) — $121.90. More water, less height, plus a check valve and a hair blade. 500 W — 29.1 gpm (110 LPM) at 26 ft (8 m) — $109.90.

If the pipe climbs, this one. If it runs mostly flat and a shower feeds it, the 800 W — because a check valve and a hair blade are worth more than two meters of head you never reach.

And the two absences

No check valve. The maker’s own 800 W has one, and without it the standing column in the discharge pipe falls back into the tank at every stop — more cycles, more residue, more smell.

No certification. The Saniplus publishes CSA (IPC, NSPC) and IAPMO (UPC), which is what an inspector asks for. Five of these six pumps publish none, and this is one of them.

Strengths, and the catches

Strengths

A delay circuit that reduces how often the pump starts, which is the thing that wears a macerator out and the noise people complain about
Forty feet of lift and 48 GPM, the strongest duty published on this shelf, with inlet sizes and a 167 °F rating as well
Fourteen cents a watt, with an IPX8 oil-filled copper motor

Compromises

Forty feet of lift is published with no horizontal run, and the two pumps here that give both show one foot of rise costs ten feet of run
No check valve published, where the maker’s own 800 W model has one
No certification and no warranty, against the Saniflo’s CSA and IAPMO listings and four-year warranty

The questions we get

What does the PCB delay function actually do?

It stops the pump short-cycling. A macerator starts when the float in its tank rises and stops when it falls, and if the switching is tight it will fire for two seconds every time a sink drains — dozens of times a day, each start drawing the inrush current of a 1.2 horsepower motor. A delay circuit waits a little before starting and runs slightly longer, so the number of starts falls sharply. VEVOR gives both consequences: "quieter operation and extending the macerator pump’s overall service life". Motor starts are what kill pumps, far more than running hours, and this is the only listing on this shelf that addresses the switching rather than the hydraulics.

Is forty feet of lift comparable with Saniflo’s fifteen?

Not directly, and this is the most important caution on the shelf. Maximum head is measured at the point where flow falls to nothing, and it tells you where the pump stops working rather than where it works well. Saniflo publishes 15 feet vertically or 150 feet horizontally — a working duty, with the trade-off stated — and backs it with CSA and IAPMO certification. VEVOR publishes 40 feet and no horizontal figure. Both may be honest measurements of different things. What you can rely on is the ratio the two listings that publish both numbers agree on: one foot of rise costs about ten feet of run. Ask VEVOR for the horizontal figure before planning a long basement route.

Which of the three VEVOR pumps should I buy?

It depends on the shape of the pipe run, and VEVOR’s figures are consistent enough to choose from. The 900 W does 47.6 gpm (180 LPM) at 39 ft (12 m) — the strongest lift here. The 800 W does 52.8 gpm (200 LPM) at 33 ft (10 m) and adds a built-in check valve and a hair blade for $8 less. The 500 W does 29.1 gpm (110 LPM) at 26 ft (8 m) for $20 less than this. If the pipe climbs, this one. If it runs mostly flat and a shower feeds it, the 800 W, because the check valve and the hair blade matter more than two meters of head you will not use.

An upgraded PCB delay function reduces the frequency of startups.	NOT PUBLISHED BY THE MAKER, and no check valve is published.	Four — one 3.50 in (89 mm) and three 1.57 in (40 mm).	Up to 167 °F (75 °C) / 167 °F, stated for washing machines and dishwashers.
VEVOR 800 W macerator pump	$122	32.8 ft / 10 m, on an 800 W pure copper motor stated to run cooler, flowing 52.8 gpm (200 LPM) / 12,000 L an hour — $0.152 a watt on October 29, 2026, the second lowest published rate on this shelf after the maker's 900 W at $0.144. 13.9 lb (6,300 g).	NOT PUBLISHED BY THE MAKER. A CHECK VALVE IS BUILT IN, stopping wastewater backflow — one of only two backflow protections on this shelf.	Four, draining washing machines, bathtubs and sinks SIMULTANEOUSLY.	NOT PUBLISHED ON THIS LISTING — WHERE THE SAME MAKER PUBLISHES 167 °F ON TWO OTHERS ON THIS SHELF. On a pump sold for washing machines, that omission is the one worth noticing.
VEVOR 500 W macerator pump	$110	26 ft / 8 m, on a 0.7 HP / 500 W oil-filled copper motor, IPX8 waterproof, flowing 29 GPM / 110 LPM — $0.220 a watt on October 29, 2026. 13.2 lb (6,001 g), 16.5 × 6.30 × 11 in (420 × 160 × 280 mm).	NOT PUBLISHED BY THE MAKER — and on this shelf the two listings that do publish one give 150 and 360 ft, so the figure is neither small nor unknowable. NO CHECK VALVE is published either, where the maker's own sewage pump here builds one in.	Four — one 3.50 in (89 mm) and three 1.57 in (40 mm), so a toilet and three gray-water lines.	Up to 167 °F (75 °C) / 167 °F, stated for washing machines and dishwashers — one of two on this shelf that publishes a temperature at all, and the figure that says whether a hot wash cycle will ruin it.
SILENTFLO+ 750 W macerator pump	$249	Up to 36 ft, on a 750 W industrial-grade pure copper motor — $0.332 a watt, THE HIGHEST of the four pumps here that publish a motor rating, more than twice the cheapest (Amazon.com prices of October 29, 2026). 16.0 lb (7,257 g), 15.4 × 6.69 × 10.2 in (390 × 170 × 260 mm). THE FLOW RATE IS NOT PUBLISHED, so the lift figure stands alone.	UP TO 360 FT — THE LONGEST PUBLISHED ON THIS SHELF, more than twice the Saniflo, and the figure that decides whether a basement bathroom can reach the stack at all. No check valve is published.	Four — toilet, sink, shower and kitchen drain, stated for basements, cabins and garages, complete bathrooms and combined utility rooms.	NOT PUBLISHED BY THE MAKER.
