VIDEO: How To Install A Sump Pump
FAQs ABOUT SUMP PUMP
Q: What is the advantage of ‘top suction’ design of WAYNE CDU980E pump?
The ‘Top Suction’ design allows a pump to draw water from the top of the cast iron base, not from the bottom of the pump. So, the top suction pump avoids sucking in debris, garbage, sludge, and dirt from the bottom of the basins.
Q: What type of water does WAYNE CDU980E pump handle?
CDU980E pump only works for removing rainwater and clearing groundwater. Its design doesn't allow it to deal with salty, briny, gray, or septic water. A pump must have a specific rating to qualify for working with salty water.
Q: Will Superior 91250 Pump handle dirty or muddy water?
Superior 91250 pump works well on the sludgy mixture, mini algae, and liquidated snow. It will be wiser to place a suitable fabric below the pump to prevent the sucking of mud. Also, the suction screen should be cleaned routinely to prevent motor overheating and avoid a low flow rate.
Q: Is it allowed to let a sump pump suck air or run dry?
Sucking of air will cut short pump life. Exposing the pump to sucking too much air will result in the burning of the pump motor.
Q: What is the least depth of water necessary for sump pump to operate?
Generally, sump pumps having bottom intakes start working at 1 inch to 1.5-inch depth. While taking in water, some pumps might go as low as ¼ inch to ⅛ inch.
Q: Is it ok to submerge superior sump pump in hot tub?
The superior sump pump can bear as high a temperature as humans do. It could be a maximum of 50o Celsius.
Q: Are cast iron pumps preferable or not?
Cast iron pumps have several advantages. The heavyweight of cast iron pumps makes them durable and long life. Weight allows the cast iron pump to run noiselessly with negligible vibration. For underwater use, cast-iron pumps are superior to lighter pumps. Cast iron pumps do not move to reduce the risk of float jamming. Cast iron pumps do not tip over very often.
Q: Will Wayne WSS30VN run if backup pump not connected to battery?
The primary pump will still run even if the backup pump is not hooked to a battery. The backup pump only starts when a power outage occurs. Both are independent of each other.
Q: How to convert Superior 91570/91250 pump into sump pump?
Superior Pump 91570/91250 has provision for installing a float switch. Installing a float switch will transform the pump into an automatic on/off one, then it can be used as a sump pump.
Q: How to differentiate between submersible and sump pump?
In practice, both submersible and sump pumps are submersible. But, they operate differently. A submersible pump remains entirely submerged for the whole duration of work. It might even sit at the bottom of the water body. Alternatively, a sump pump might immerse for a short period, only to emerge gradually as the water level comes down.
SUMP PUMP BUYING GUIDE
If you are aware of frightening basement incidents, you would probably want to prevent such things from happening. Waterlogging in the basement would incur high costs for water removal, damage repairs, and subsequent rehabilitation. The best way to avert basement water problems is by installing a suitable sump pump in your basement. A Sump pump automatically detects basement water level then pumps the water out to a drainage zone to ensure a warm and dry basement and interior of a building. So buying a sump pump is like a one-off investment that will save you from plenty of troubles and unwanted expenses resulting from water buildups.
There are various kinds of sump pumps available in the market, each having pros and cons. So, while purchasing a sump pump, some features need to be given due consideration. Here we have tried to make sump pump buying a smooth experience and drawn up a humble and pragmatic buying guide.
Pump design-
Sump pumps are available in two designs which are submersible and pedestal.
Submersible pump-Submersible pumps sit entirely inside sump pits and work submerged in water, therefore, allowing to place cover overhead. The cover helps reduce the noise also prevents dust from reaching the basin. Their motors are encapsulated by the pump body and sealed from moisture. Submersible pumps run quietly and lower moisture levels in the basement. They are usually self-cooling.
Pedestal pump-As for the pedestal pump, the base, float, and discharge pump sit inside the sump pit, while the motor sits outside the sump pit. Pedestal pumps are usually louder since their motors sit out of the sump pit. It is not suitable to use a cover with a pedestal pump resulting in a humid basement. But they have a longer life since they are not submerged.
Anyway, the best configuration is determined by the size of a sump pit.
Mode of operation-
Both manually and automatically operated sump pumps are available. A Manual sump pump won't start automatically. Manual sump pumps are turned on and off by manually connecting/disconnecting the power cable into an electrical outlet. Whereas automatic sump pumps have an integrated switch mechanism that automatically turns on/off the pump when certain conditions meet.
Power source requirement-
Electrically powered sump pumps are the most common. However, a power outage or disruption will abruptly shut the pump. Conversely, a sump pump with a backup battery will keep running even if a power failure stops the pump. There are also combination sump pumps that bundle together an electrical powered primary pump with a battery backup secondary pump. So, if the primary pump fails for any reason the battery backup pump will start automatically.
Horsepower strength-
1/4 HP (Horsepower) and 1/3 HP (Horsepower) sump pumps are the most commonly used in homes. However, for extraordinary situations like storms, floodwaters 1/2 HP or a more powerful sump pump is better.
Pump core material (Housing)-
Sump pumps core constructed using varieties of materials such as anti-corrosive stainless steel, anti-rusting anti-corrosive thermoplastic, solid cast iron, epoxy-coated stainless steel. All these materials heat up during pump running, which wears them out. However, heavy-duty cast iron will outlast the other materials.
Pump head pressure-
Pump head pressure indicates the maximum distance or height that the pump can discharge water.
Switch-
Two types of switches are available mechanical float switch and sensor-based pressure switch. Mechanical switches with a solid float are preferable.
There are a few more things that could be looked into whilst buying a sump pump they are water level alarm, intake/suction screen, silent check valve also known as "klunkless" valve that prevents noise during pump shut down, alert feature.
Conclusion:
At last, we have reached the end of this best sump pump review. Buying the right sump pump isn't an easy task as you will weigh in several factors like where to install it, how long drainage line you need, what is the discharge height, how powerful motor you need, what configuration pump do you want, and above all what is your budget limit.
We have reviewed some of the most deserving brands and models. Hopefully, this sump pump review has been a helpful guide for you in selecting the perfect model for your specific conditions and requirements. Have a good luck!
