The most common complaint was damage during shipping. Several reviewers state that the device was damaged during shipping due to poor packing. When receiving a damaged pump, contact customer service immediately. Be warned, however, that the company’s customer service department has a bad reputation.
The pump is activated by a float on the side of the device which flips a switch when the water gets to the top. Reviewers like this design over a sensor which could get dirty or a floating cup which could get stuck. Some reviewers complain the water is not completely removed because the float does not go all the way to the bottom of the pump. The small travel distance of the float means the pump will run for short periods of time but will activate more often. The Zoeller 98-0001 Sump/Effluent Pump can easily handle a high volume of water. Reviewers recommend purchasing the extended warranty available through Zoeller.

If you live in an area with frequent heavy rains, where floods constantly occur, a sump pump is an absolutely necessary device in order to keep your basement and the rest of your house dry.
Deciding on the right type of device without advice from a professional can often be a daunting task, not to mention that, by purchasing a product that does not suit your needs, the money you invest in it are wasted.
Pumps used to sump are of two types: submersible pumps and pedestal pumps. Those from the first category are more expensive and they cannot be installed without the help of a professional plumber.
A pump of this type costs more than a pedestal pump, the fee charged by the professional who sets it being added to its price. The pedestal must be placed at the sump hole bottom, completely covered by water. This type of pump has a life duration between 5 and 15 years, and the price you pay for it does not exceed 500 $.
On the other the other hand, pedestal pumps can be as cheap as 60 dollars and they can last for a period of 25 to 30 years, the model being appreciated in favorable terms by many people who post sump pump reviews.
This type of device is also easier to install compared to a submersible pump, as you can perform the entire operation by yourself, without the assistance of a professional being necessary. This model of pump is composed from a motor, placed at its top, and the pump itself, at the bottom. It is placed at the base of the sump hole, without being submerged into the water.
Regardless of its type, you have to be prepared for the eventuality of the main pump’s failure, so you must consider buying a backup pump. One of the two available types of sump pumps for backup can be directly connected to your main plumbing system, functioning with the help of water pressure. The other kind of backup sump pump is powered by a rechargeable, 12-volt battery.
In order for the pump to fit in properly, the sump hole must have about two feet in diameter. A layer of gravel, having the thickness of 3 or 4 inches, must be put on the bottom of the hole, in order to prevent the accumulation of debris and dirt into the pump.
When it comes to choosing the best sump pump, it is always indicated to do an extensive documentation and comparison between the prices and technical characteristics of the two types of devices, as the durability of your home depends on this.
