The Simer 2925B is a popular sump and laundry pump system that comes with a 1/4 HP pump, 6 gallon basin and 1.5″ discharge pipe. In this article we reviewed the self contained system to see if it is a good choice for your home or if you would be better off going with another option.

All in one systems like this Simer model offer many advantages over piece meal systems because you know each part is going to work together. There is nothing worse than buying a new part for your basement drainage system and getting home and realizing it does not fit with your pump or drain lines.

Pump Information

The pump on the Simer 2925B is only a 1/4 HP which is not as powerful as some of the larger pumps on the market but is still a good option if you don’t need a very powerful pump. The pump has a max head height of 18 feet and can pump 1620 gallons of water per hour at 10′ head.

Another advantage is that it can pass small solids though the motor without causing damage. Some basins receive lots of small particles and rocks in the sump water and that can damage and destroy weaker pumps – especially once they touch the internal impeller.

Basin Information

The basin on the Simer 2925B holds 6 gallons which is good for small to medium-sized homes. It is made of solid plastic that holds up well to the stress and pressure of being in the basement elements. The basin cover provides protection for the sensitive pump and keeps extra particles from falling into the pit.

There are three holes in the top, two for the drain lines and one for the power cord which means it is not airtight.

Drain Line and Other Parts

Drain Lines
The drain lines on this unit are the standard 1 1/2″ NPT drain lines. This is good because you will not need to retro fit your system with new size piping, they can handle a high flow rate and can withstand seasonal elements in the basement.

Float Switch
This Simer pump is activated by a vertical float switch inside the basin. Vertical switches are highly reliable and will turn the pump on and off as the water level rises and falls. The only risk is the float switch getting stuck!

Check Valve
Check valves keep water flowing in one direction and prevents backflow into the basin. This unit has a built in check valve so you will not need to attach a separate part to your drain line.

Power Cord
The power cord is one of the most important and most often forgotten about parts of a sump pump. A good power cord should be at least 10′ long so it can reach across the room, waterproof and well insulated. Without a working power source even the most powerful pumps can cause a flood. The power cord on this model attaches to the top of the pump and runs through a small hole in the middle of the lid.

Internal Impeller
The impeller is responsible for pushing water inside the motor. The impeller on the 2925B is well built and can pass small objects like rocks and pebbles without causing any internal damage which is a common source of failure in other pumps.

Our Final Say

We think the Simer 2925B is a great choice for a sump pump or laundry pump in small to medium sized houses. Since it is an ‘all-in-one’ system both installation and maintenance are easy. The only downsides to be aware of are that the motor is only 1/4 HP and the unit does not include a backup battery or alarm
