VEVOR 800 W macerator pump review

Q: Why does a check valve matter so much on a macerator?

Because a macerator pumps upwards. When it stops, the column of water standing in the discharge pipe — which may be ten feet of it — has nowhere to go but back down into the tank. Without a check valve that happens every single cycle: the pump grinds and pumps the same waste repeatedly, it runs far more often than it needs to, and the tank is left holding more residue, which is what produces the smell people complain about. A check valve holds that column up. Two listings on this shelf publish one — this and the Saniflo Sanishower at $403.92. Four do not.

An 800 W macerator pump with a built-in check valve, a hair-reducing bottom blade and a PP housing.

By Jean-Benoit Buisson

What the maker puts in writing

“This macerator pump features a water-electric separation design to keep water away from the motor, a bottom blade to reduce hair clogs, and a built-in check valve that stops wastewater backflow”
“With an 800W motor and a max flow rate of 200 LPM, this upflush toilet pump handles simultaneous drainage from washing machines, bathtubs, and sinks. With a 32.8 ft / 10 m max lift, it easily pumps wastewater to main drain line”
Compact for tight spaces, for sinks, showers, kitchens and laundry rooms
“Crafted with a pure copper motor, this laundry sink drain pump runs cooler for extended service life. The corrosion-resistant PP housing resists warping and cracking”
“The breathable discharge valve helps block unpleasant smells and keeps indoor air fresh”

The check valve

This is the feature that justifies this page, and four of the six pumps on this shelf do not have it.

A macerator pumps up. When it switches off, the water standing in the discharge pipe — perhaps ten feet of it — has nowhere to go but back down into the tank.

Without a check valve, that happens every cycle. The pump grinds and lifts the same waste again. It runs far more often than it needs to. And the tank is left holding more residue between uses, which is where the smell comes from that people blame on the product.

A check valve holds the column up.

Two listings on this shelf publish one: this, and the $403.92 Saniflo Sanishower.

And a blade at the bottom, for hair

The failure that actually stops a shower-fed macerator is not solids. It is a felted mat of hair that wraps the shaft and stalls the impeller.

A bottom blade to reduce hair clogs.

No other listing on this shelf names the problem. SILENTFLO addresses something adjacent with a “360° shredding structure” for fibrous waste; Saniflo offers hardened stainless blades.

A macerator fed by a shower sees hair every day and solids occasionally. This is the right thing to have designed for.

Water away from the electrics

A water-electric separation design to keep water away from the motor.

Which is a different approach from the maker’s own 500 W and 900 W pumps, where the answer is an IPX8 oil-filled motor — sealed and flooded with oil so water cannot get in.

Both are legitimate. Keeping the water away is arguably better than sealing the motor against it.

And a PP housing — polypropylene, which does not corrode and does not go brittle the way cheaper plastics do in a warm damp basement.

The best watts per dollar here

$0.152 a watt on October 29, 2026, against $0.144 for the maker’s 900 W, $0.220 for its 500 W and $0.332 for the SILENTFLO. The two Saniflos publish no motor power at all.

And the highest published flow of the three VEVORs: 52.8 gpm (200 LPM).

Why the 800 W moves more water than the 900 W

Because it lifts it less far, and VEVOR’s figures are honest about the trade.

Hydraulic work is flow times head. 800 W: 52.8 gpm (200 LPM) at 33 ft (10 m) = 2,000. 900 W: 47.6 gpm (180 LPM) at 39 ft (12 m) = 2,160. The ratio between those, 1.08, is close to the ratio of the motors, 1.125.

So these numbers come from a real pump curve, not from a brochure. That is unusual enough to say plainly.

Long and flat: this pump. Steep climb: the 900 W.

Two things not on this page

No water temperature — which is odd, because VEVOR publishes 75 °C / 167 °F on both its other pumps here, and it is the figure that says whether a washing machine can discharge into it. The bullets mention washing machines without a figure.

No horizontal run. As on both VEVOR siblings, the lift is published and the run is not — and the two pumps on this shelf that give both show that one foot of rise costs about ten feet of run.

No certification either, where the Saniplus publishes CSA and IAPMO.

Strengths, and the catches

Strengths

A built-in check valve: only two pumps on this shelf have one, and it is what keeps the discharge pipe from draining back into the tank
A bottom blade specifically against hair, which is what actually blocks a shower-fed macerator
Fifteen cents a watt, within a cent of the best published rate on this shelf, and the highest published flow of the three VEVORs

Compromises

Publishes no water temperature, where the maker publishes 167 °F on its own 500 W and 900 W pumps
No horizontal run figure, so a long basement run cannot be sized from this page
No plumbing certification, where the Saniflo here publishes CSA and IAPMO listings

Stated horizontal run	NOT PUBLISHED BY THE MAKER. A CHECK VALVE IS BUILT IN, stopping wastewater backflow — one of only two backflow protections on this shelf.
Inlets	Four, draining washing machines, bathtubs and sinks SIMULTANEOUSLY.
Maximum inlet temperature	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.
Discharge diameter	NOT PUBLISHED BY THE MAKER.
Stated noise level	NOT PUBLISHED. What is published is a bottom blade to reduce hair clogs, a water-electric separation design keeping water away from the motor, a corrosion-resistant PP housing resisting warping and cracking, and a breathable discharge valve to block smells.

The questions we get

Why does a check valve matter so much on a macerator?

Because a macerator pumps upwards. When it stops, the column of water standing in the discharge pipe — which may be ten feet of it — has nowhere to go but back down into the tank. Without a check valve that happens every single cycle: the pump grinds and pumps the same waste repeatedly, it runs far more often than it needs to, and the tank is left holding more residue, which is what produces the smell people complain about. A check valve holds that column up. Two listings on this shelf publish one — this and the Saniflo Sanishower at $403.92. Four do not.

What is a bottom blade for?

Hair. A macerator grinds with blades at the impeller, and the classic failure on a shower-fed unit is not solids but a felted mat of hair that wraps around the shaft and stalls it. VEVOR’s answer is a blade at the bottom of the chamber where that mat forms. It is the only listing on this shelf to name the problem, and it matters because a macerator taking a shower drain will see hair every day while it may see solids only occasionally. SILENTFLO addresses something adjacent with a "360° shredding structure" for fibrous waste, and Saniflo with hardened stainless blades.

How can the 800 W pump claim more flow than the maker’s 900 W?

Because it trades height for volume, and VEVOR’s three pumps are internally consistent about it — which is rarer than it should be. Hydraulic work is flow multiplied by head. The 800 W does 52.8 gpm (200 LPM) at 33 ft (10 m), which is 2,000; the 900 W does 47.6 gpm (180 LPM) at 39 ft (12 m), which is 2,160. The ratio of those two, 1.08, sits close to the ratio of the motors, 1.125. So the figures come from a real pump curve rather than from a marketing meeting: this pump moves more water and lifts it less far, which is exactly what the physics requires. If the run is long and flat, this is the better pump. If it has to climb, the 900 W is.
