How Does A Sump Pump Work?

An excellent question! And there is a great video that explains the process in a very swift and understandable way.

Types of Sump Pumps

Pedestal Sump Pump

Pedestal sump pump made by Superior, model 92301

A pedestal sump pump has a motor mounted above the pump on a shaft. This keeps the motor out of the sump basin. This design is less expensive to manufacture and maintain. A shaft extends from the motor to the impeller of the pump, which sits within the sump basin. They are ideal for both shallow and deep sumps. They fit smaller budgets and typically last 25 years or longer. Because of their height, they should be braced or tied to a nearby support.

Submersible Sump Pumps

A submersible sump pump is designed to be completely under the water it is pumping. They need a sump deep enough to completely cover the unit. Due to its compact size compared to a pedestal style sump pump, most people find it easier to handle and like that it is out of sight below the floor. A typical lifespan for a submersible pump is 10 to 15 years.

Portable Sump Pumps

A portable sump pump is used in areas that flood infrequently. They typically are powered by an electrical cord or an attached gasoline motor. Some require priming with water because they are not designed to suck up water but rather to push it. Intake and outlet hoses usually must be provided to transport the water a safe distance away. Running a portable sump pump dry can quickly damage the impeller or burn out the motor so they should be monitored.

Backup Sump Pumps

If the power goes out while a primary sump pump is operating, a backup sump pump that runs on either a battery or water pressure turns on automatically and continues removing excess water. Water-powered sump pumps get their power from the pressure of your city water supply, so can run indefinitely, whereas battery-powered backup pumps run from a lead-acid battery. Backup sump pumps include alarms to indicate when they are operating.

Battery Backup Sump Pumps

A battery-powered backup pump will work as long as its battery has a charge. Typically, a marine-grade, deep-cycle 12VDC battery is used, which is continually charged while the mains power is on. Although these pumps do not come with a battery, they usually have a sealed battery box, a charger, check valve and plumbing connections to insert it in parallel with your existing sump pump plumbing.

Why You Should Invest in a Sump Pump

The purpose of a sump pump is to remove excess water that occurs due to flooding or a high water table. If you have evidence of past flooding or any concern about future flooding, installing a sump pump is a wise idea. It avoids a host of problems:

• Water damage -- Excessive water can damage your home’s structure or finish materials such as carpets or paneling.
• Mold – Excess moisture leads to mold growth in the structure and personal belongings.
• Rot – Other fungi that destroy wood, paper, clothes, etc. also love moisture.
• Rust – Anything metal in your basement can suffer from corrosion by either contact with accumulated water or from excessive humidity.
• Impaired air quality – Mold or other fungi create an unhealthy environment for the home’s occupants.

Why Do You Need a Backup Sump Pump?

Your primary sump pump will stop working during a power outage or due to mechanical failure. A backup sump pump has a power source separate from mains power, its own pump, check valve and plumbing to bypass the primary pump. Unattended, it will kick in and keep moving water when the primary sump pump is out of commission.

Check for these features when selecting a backup sump pump

• For a battery-powered backup pump, be sure it can charge a deep-cycle battery
• It should have a similar pumping capacity as the primary pump
• It must have its own check valve
• A water-powered backup pump is not appropriate for a house that gets water from a well.

Why Should You Listen to Me?

Having owned houses with basements, I have firsthand experience with all the pump types covered in this guide. As a home builder and renovator for two decades, I also installed or replaced sump pumps of all types in dozens of homes. Additionally, for this guide I have consulted over 20 experts including plumbers and sump pump manufacturers to acquire detailed specs and advice about designs, installation techniques and how to avoid maintenance and repair problems. Where any gaps in my knowledge still existed, I filled those by researching product descriptions, review sites and online forums populated by experts in pump technology.

How to Use a Sump Pump

A video from the North Dakota State University Extension Service provides an excellent overview of how a sump pump works and how to test its operation.

You should always test a new sump pump installation to familiarize yourself with its operation and determine that everything is working properly. The same steps should be applied every year:

• Be sure that the circuit from which your sump pump draws power is properly grounded and uses a GFI outlet.
• There is no reason to remove the sump pump when checking its operation, but if you do make sure its electric supply is disconnected.
• Remove the cover from the sump, if any.
• Removed debris from the sump basin. Too much debris plugs the pump’s inlet ports.
• With the pump connected electrically, fill the sump from the bottom with a garden hose or bucket.
• Watch that the float rises smoothly and continuously as the water level rises.
• When the pump turns on, it should not hesitate or cycle on and off quickly.
• There should be no unusual noises such as squealing or scraping when the pump starts or runs.
• Turn off the garden hose and observe the pump’s operation until it turns off.
• After the pump turns off, you should hear the check valve close in the outlet pipe.
• Repeat the entire test one more time to be sure everything works as expected.

The most important adjustment you can make is the length of time the pump runs after it turns on. This is controlled by the float switch. The duration of the on cycle is determined by the length of travel of the float. A longer travel distance allows the pump to operate with fewer on/off cycles, which increases the life of the pump.

Sump Pumps: What to Look for

A pedestal pump is more tolerant of different sump sizes. Most submersible pumps need a wider sump basin. Other than the sump pit size, both kinds of pumps, and other types as well, can be evaluated according to the following characteristics.

Capacity

Be sure to buy a sump pump that has adequate pumping capacity. This is measured either as gallons per minute or gallons per hour. Both of these figures are measured at a specific head height, which is how high the water is pumped. As head height increases, GPH decreases. If a particular sump pump does not list a chart of GPH versus head height, pass it over. If the maximum head height it can pump is less than the distance from your sump to the top of the outlet plumbing, it will not work for your situation.

Power

Sump pump power is measured in horsepower. If you are replacing a sump pump that was working adequately, buy another one with the same horsepower or higher. A 1/3-HP sump pump is adequate for most situations. If you have to pump the water higher than 10 feet or further from the house than 50 feet, then purchase one with a power of at least ½-HP up to 1 HP.

Float Type

Sump pump floats come in different configurations. Pedestal sump pumps have a float on a long rod that rises with the level of the water. They usually have the longest travel of any pump type up to 10 inches. Submersible pumps use floats with shorter travel on a rod of four inches give or take. Some submersibles use a tethered float, which permits up to eight inches of travel. The longer the travel, the fewer times the pump will have to cycle power. Solid floats are superior to hollow floats as they never become waterlogged.

Switches

You should only purchase a sump pump with an automatic switch so it can run unattended. Furthermore, the switch should be mechanical and not a pressure switch. Otherwise, the type of mechanical sump pump switch is unimportant.

Inlet Size

A sump pump impeller that can handle debris up to ½-inch diameter is recommended. Metal impellers will withstand hard debris such as pebbles better than plastic impellers.

Materials

Sump pump motors, especially pedestal style pump motors, can generate a lot of heat if they must run continuously. Thus, the best pump motors have a cast iron core rather than plastic in order to more effectively dissipate heat.

Price

All other things equal, a sump pump of higher horsepower costs more than a smaller pump. Other than power, the price will reflect the cost of the materials used to make the pump such as the type of metal used in bearings, bushings and the housings.

Warranty

Check the length of warranties and what they cover when comparing sump pump brands. Do not expect much, however. Since sump pumps work under unpredictable and adverse conditions, most manufacturers do not grant more than one or two years of warranty.

How We Picked Sump Pumps

Sump pumps have a vital job to perform. They must remove accumulated water in your basement or crawlspace automatically and with high reliability in order to avoid costly damage. Often, they are called upon to perform this function during times of extreme weather. Furthermore, they may pump unclean water containing debris.

Homeowners prefer sump pumps that they set and forget, which sometimes means the pumps must continue to operate even without regular maintenance. Thus, we look for sump pumps that are rugged, made of quality materials and do not play games with their specs. For instance, if a pump hedges the GPH/Head figures in any way, we consider that a sign of a weak pump. The best manufacturers tell you straight up how the pump will perform so that you can judge for yourself whether it is the right pump for your situation.

Tips on How to Maintain Your Basement

• Keep a cover over the sump. If you live in an area where radon in the soil is an issue, cover and seal this lid with plastic and tape.
• Make sure the lot grade slopes away from the house in all areas and water cannot puddle near walls.
• Even during heavy rains, gutters, downspouts and footing drains should handle all the runoff.
• River rock around the basement periphery and in window wells absorbs water that could penetrate basement walls.
• Vent bathrooms and clothes dryers to the outside of the house. Do not hang wet clothes in the basement.
• Insulate cold water pipes so that condensation does not form.
• Install a dehumidifier if humidity remains high after ensuring you have implemented the steps above.

• Measuring tape and felt marker
• A flat blade screwdriver
• One or two rubber couplings with hose clamps the same size as the outlet pipe
• Ratcheting PVC snips or a PVC pipe saw
• PVC primer and PVC cement
• A few 6-inch zip ties
• A portable, bottom-inlet utility pump such as the Superior 91250

If you are replacing an existing sump pump with the same or different model, these are the initial steps to follow:

• Keep a utility pump nearby for cleaning up plumbing water and removing water in the sump basin
• Disconnect power from the old pump
• Set aside the sump basin lid
• Remove or disconnect the existing outlet check valve
• Lift the old pump from the basin using the vertical portion of the outlet pipe
• Remove any water and sediment from the basin

To continue replacing an existing sump pump or for a new installation, follow these steps:

• Add a coupler or adapter to the discharge fitting on the new pump that is the same size as the discharge pipe
• Attach a length of outlet pipe to the pump’s discharge fitting or coupler that extends a foot or so above the top of the sump basin
• Use the outlet pipe to lower the pump into the basin
• Be careful that the pump float does not come in contact with the basin wall
• Mark, cut and dry fit the remaining PVC outlet pipe being sure to include a check valve
• When all the outlet plumbing is assembled dry, mark each coupling and pipe it fits over or into with the felt marker so that it can be re-assembled in the same manner

Assemble the outlet plumbing using PVC primer and glue

• Zip-tie the pump’s power cord to the outlet plumbing to hold it in place
• Re-connect power to the pump
• Test the installation by filling the sump with water and observing pump operation

Making the Decision

Clearly there are many choices with regard to the size, configuration and quality of sump pumps to consider when making your sump pump buying decision.

Your first consideration should be selecting the correct size of primary sump pump that will adequately remove all the water flowing into the sump pit even during the heaviest rains. If you have an existing sump pump that was performing this function well up until its demise, then buy one with at least the same head lift and flow capacity. If you have any doubts at all about the correct size of sump pump, buy one at least one size larger. The little bit extra you pay for, say, a ½ HP pump versus a 1/3 HP pump pales in comparison to the prospect of standing water in your basement.

Next, compare the quality of pumps from different manufacturers. Here, the best information comes with this guide and product reviews by verified buyers. Discount sites with only a few reviews of a particular product. Also, consider the length of the warranty and the type of materials used in each pump. Ask a couple of local plumbers for their opinions about specific pump brands.

Always include in your sump pump budget room to buy either an automatic battery backup pump or at least a good quality portable pump as insurance against a primary pump failure. Sump pumps are generally reliable, but all it takes is one failure when you need it most to cause irreparable damage to belongings or your home’s structure.

Keep in mind that any sump pump should last at least 10 years and many last up to 30 years. Always buy the best basement sump pump possible, since the cost will be amortized over those 10 to 30 years. If you choose a pump because it is a hundred dollars cheaper, is the three to 10 dollars per year you saved really worth the doubts or lost sleep you might suffer?

Whichever pump you finally decide on, make sure it is installed correctly and do not forget to perform maintenance on it at least once a year to keep it running smoothly and reliably.
