Simer 2925B Sump/Laundry Sink Pump Reviews

Those familiar with our how to install sump pump guide would know that a substantial part of the procedure involves creating and preparing the sump. Now while many homes come with ready-made sumps, the presence of sump liner, etc. often cannot be taken for granted. Enter the Simer 2925B Sump/Laundry Sink Pump, which comes with an external shell made of foam that makes such liner unnecessary.

At the same time, the unit is capable of providing drainage and durability similar to the who’s who of the sump pump market. However, one may wonder whether the unit is really that durable, or whether the inclusion of an outer shell has led to some corner-cutting. A detailed review will address such concerns.

  • Sturdy outer shell and excellent thermoplastic design allow for a durable producSupport for multiple PVC pipe diameters, default PVC pipe provided with the package.
  • Excellent motor capacity with remarkable shut-off point.
  • Double protection for the motor in the form of hermetic sealing and external shell.
  • Sturdy impeller and fixed nature of unit contribute to enhanced impeller efficacy.


  • Fixed size of the external shell may make the unit difficult to use in tiny sumps.
  • Lack of handle makes unit difficult to move.

At its core, the Simer 2925B Sump/Laundry Sink Pump comes with a standard thermoplastic housing and a somewhat elevated base that allows the impeller to avoid scraping against the base of the external shell. A standard plastic float is located to one side of the unit, such that the unit can be activated when 1/4th of the shell has been filled with water.

Coming to the external shell, we find that it has been made of a durable hard foam that keeps the water at bay while ensuring that fungal growth does not take place. The top of the shell can be completely open, or if used in certain other situations, closed and feature two sets of pipes, one bringing in the water to be removed and the other removing it. In either position, though, the core parts are well protected by the shell, while the shell design ensures less accumulation of debris, thus reducing the frequency of sump pump maintenance procedures.

While some people contend that the presence of a large amount of foam and plastic in the unit makes it vulnerable to damage from floating debris, one has to remember that sump linings are made of the same foam as the external shell, and the use of thermoplastic has become increasingly prevalent in the industry. Indeed, the durable thermoplastic allows the unit to withstand water temperatures of up to 130 degrees Fahrenheit.

Major External Parts (Discharge and Power Cord):-

The unit comes with a standard thermoplastic discharge with a width of 1-1/2” NPT, though pipes with a width of 1-1/4” are also acceptable courtesy of a unique design modification. Interestingly, because the base is elevated, the amount of pipe needed to move the water out of the sump is marginally lower than what normally would be necessary. Further, unless one wants to make specific modifications, one can use the pipe provided by the manufacturer, and then connect this pipe to the outer PVC pipes of the basement. Lastly, the excellent design, coupled with these features, allows the unit to remove solid spherical debris with diameters of 1/8th inch or less.

The power cord, on the other hand, is designed to handle constant water flux and is, therefore, durable and water-resistant. However, the fact that it curls around the top of the unit when it comes out of a dedicated opening in the cover of the external shell, (not to be confused with the sump pump cover, which sits at the mouth of the sump) shortens the effective length of the wire. However, since the cover will rarely be used in sump settings, this is not a criticism that extends to its core sump pump functions.

Motor and Sealing:-

The Simer 2925B Sump/Laundry Sink Pump comes with a 1/3HP motor similar to that used in market leaders like the Zoeller M53 Sump Pump. In the case of this offering by Simer, such power translates into an impressive 2880GPH at 0’ head and 1620GPH at 10’ head. With a shut off point of 18’, this unit is capable of draining the vast majority of basements.

Such efficiency, of course, can only be achieved when the motor is housed in a safe environment, and this is obtained by providing a hermetically sealed, oil-filled chamber for the motor to work in. Coupled with the enhanced security offered by the external shell, this allows the motor to stay insulated from even the worst debris flux.

Switch and Impeller:-

The Simer 2925B Sump/Laundry Sink Pump avoids carrying out any unnecessary innovations when it comes to the switch, offering a traditional float switch with a sturdy switch connector above it. The location of the switch, as mentioned above, allows it to activate the unit when water has filled about 1/4th of the shell, and this allows the motor plenty of time to remove the water.

The impeller has been afforded plenty of space courtesy of the heightened base, and this lets it use its sturdy thermoplastic blades to maximum effect. Further, since the pump is affixed to the base of the shell, there is never any risk of instability, and this helps improve the water removal power of the impeller manifold.


While some bells and whistles are being added to sump pumps by manufacturers, the key features of the best sump pump no doubt include sufficient water removing capacity and a design that allows for large operation and external flux without suffering damage. The Simer 2925B Sump/Laundry Sink Pump excels in these departments, and also, provides a unique external shell design that provides added stability and protection. While this external shell also brings with it a few minor issues, the overall combination of an excellent pump and an equally durable shell make this unit ideal for a broad range of situations.
