VEVOR ZX30024 Utility Sink Pump: 1/2 HP, 3500 GPH, specs and fit

The VEVOR ZX30024 is an under-sink pump system for places where a sink cannot drain by gravity, such as a basement laundry tub or utility sink below the level of the drain line. Water collects in a basin, and the pump lifts it out through a discharge pipe once the level rises.

How the system works

Drain water from the sink runs into a 6-gallon basin. An automatic float switch rises with the water and starts the pump, then switches it off when the level drops. VEVOR says this avoids unnecessary starts and stops, which saves energy and should reduce wear. There is no manual switch to remember.

What the flow figures mean

VEVOR rates the pump at 1/2 HP and 3500 RPM, with a maximum flow of 3500 GPH (gallons per hour). Maximum flow is measured with little or no lift. The listed maximum head of 28 ft is the greatest height the pump can raise water, and flow typically falls as the lift gets higher. For a basement sink, the vertical distance from the pump to the drain tie-in is the figure to compare against the pump's curve in the manual.

The outlet is 1-1/2 inch NPT, and the pump handles solids up to 3/8 inch. It is meant for sink water such as laundry, not for sewage or large debris.

Motor and materials

The motor is oil-filled with copper windings. In general, oil in the motor helps carry heat away, and VEVOR says the design reduces vibration and noise. The housing is corrosion-resistant cast aluminum. The listing says the pump meets ETL standards, and it is sensible to follow local plumbing and electrical codes and the manual during installation.

Installation

VEVOR describes setup as attaching the pump, the vertical switch and the discharge pipe to the basin. You will still need to connect the sink drain to the basin inlet and run the discharge line to a suitable drain, with a check valve if the manual calls for one. The system is rated for 120 volts.

Who it suits

It suits homeowners finishing a basement, adding a laundry sink or wet bar below drain level, or replacing an older sink pump. Anyone with a flood or sump problem should check that this is the right type of pump, since it is described as an under-sink utility system.

What to check before you buy

• Drain height: measure the vertical lift and horizontal run to the drain, and compare with the 28 ft maximum head.
• Connections: confirm the 1-1/2 inch NPT outlet matches your pipe and fittings.
• Space: check that the 6-gallon basin fits in the cabinet or space.
• Water type: make sure only sink or laundry water goes in, with no larger solids.
• Power: confirm a suitable 120-volt outlet, protected as local codes require.
• Upkeep: check how to clean the float and basin, and what to do if the pump runs dry.

The short version
