Do you have a basement in your home? Are you facing issues of wet basement? Are you facing the problem of basement flooding? If yes then you are not the only one facing these issues. There are many home owners who are troubled with these problems. One of the solutions of troubleshooting these issues is to have a sump pump installed in your home. In old homes which were built without adequate basement waterproofing, sump pump is the best way to get rid of the basement issues. It would be hidden in one of the deepest corners of your basement and it will be invisible to you but by far it is one of the most essential appliances in your home. The basic function of pump is to remove ground water from underneath the house. Without sump pump, water will keep coming in the house during heavy rain and it can flood your basement or even your entire house. It is usually placed on the pit which is built in your crawlspace or basement floor. Generally the concrete floor is slightly poured downhill when home is built so that the water will flow right into the pit. This water will be ejected out of the house through the pump. The pump is fitted in the bottom of the pump hole and it has a switch which is activated according to the water level in your basement. When there is water in your basement and it flows into the pit, the pump gets activated and it starts pulling the water out of the pit with the help of a discharge pipe. This discharge pipe takes the water and throws it into the designated area or drain, outside of the house. Most of the pump will discharge the water out in your backyard. Make sure to keep the exit place of the water far from your house as keeping it near to the home structure, can damage your walls. Here are some of the types of sump pumps which can be installed in your home.

Types of sump pump

  • Pedestal pumps

Pedestal pumps are considered to be one of the most common types of sump pump. Here, a motor is placed on a small pedestal. The entire unit of the pump is about 30 inches tall. There is a hose or a pipe which extends down from the motor to the bottom of the pit. There is also a float placed on a separate metal rod. Depending upon the high and low of the water level, these float also moves up and down. This is considered as a float switch. When the float is pushed to a certain height due to the water level, it activates the motor and water is sucked through the hose and is ejected through another pipe. The motor placed on this pump is designed in a way where it will always be activated before the water level reaches to a point where the pump gets submerged.

  • Submersible pumps

For locations where the sump pump will need to be under water, another type of pump can be installed in your home. It’s called the submersible pump. This unit is quite smaller, only 12 inches tall. It sits on the bottom of the sump pit. The pumps of this style contain a float switch on a rod which is similar to the pedestal pump but here the rod is only 4 inches long. This electrical switch is encased in to a hard plastic bubble. Depending upon the rise in water level, bubble also starts floating. When it is floating extremely high, it reaches to a vertical position above the sump pump and then the switch gets activated and the pump kicks on. Unlike pedestal pump, submersible pumps don’t have intake pipe which sucks up the water which has to be sent out. Instead of that, the pump is situated just at the bottom of the unit. The water is sucked up right through the bottom of the pump. There are many advantages of this type of pump. First of all, if there is any debris or any loose gravel in the sump pit then the screen or the grate in the submersible pump will prevent the gravel from getting from getting sucked up in the impeller of the pump. The impeller is a rotor machine which creates the suction in the pump. Any damage in the impeller will result in the sump pump being rendered useless. This is the benefit a submersible pump has over a pedestal style pump where the filtration process of the debris or the gravel ensures a long lasting life for the submersible pump unlike the pedestal pump.

  • Ejector pumps

If your home is full of debris and you need a pump which will be able to eject some small amount of debris without damaging the Ejector then you should avail of an Ejector sump pump. If you are having a basement which is not of concrete but just of pea gravel, then, Ejector pump is the best type of pump to opt for. Basically ejector pumps are those which can handle small debris without damage. However these types of pump are bit pricier but they are generally constructed of cast iron and they also have a 2 inch ejector port instead of the usual 1 ¼th inch port which you generally see in most of the sump pumps. This different style of impeller with increased size allows the Ejector pump to process small amount of debris and gravel without affecting the mechanism.

  • Sewage pumps

In certain situations, there’s need of the sewage pumps. In general, you will not see a sewage pump in the new houses as it is not legally allowed to install the sewage pumps without any checks and balances, in this manner. A Sewage pump is generally installed when all the waste water of the house is funneled up into the sump pit. Application of sewage pump is very rare and it needs a sewage crock with a sealed lead. All your shower water, dishwater, washing machine drainage and also your toilet drainage will be directed to the flow into the bottom of the sump pit. If this is your case then you definitely need sewage pump which will be dealing with whatever solids that flow in.

Steps for sump pump installation

  • Decide pump location

Usually your sump pump basin should be in the lowest lying position in your basement so that water naturally flows over there. Make sure that the area is properly sloped downwards. If it’s possible, try and place this slope nearby an outside wall so that the placement of discharge pipe is easy and even close to the GFCI (Ground floor circuit interrupter) electrical outlet so that you can easily plug in the pump. Also check out that this place can accommodate installation of discharge pipes so that they can remove water to a spot which is away from the foundation of the home or usually into a nearby drain. Also check whether your local codes allow you to do so or not. Before starting up with the sump pump installation, check the locations of the sewer pipes and other utility pipes. If they are located under your foundation, you don’t want to break any pipes while digging the ground of the basement and cause a bigger and dangerous problem.

  • Break ground

To measure the hole size which you are going to make, place the sump pump basin liner on the floor and then trace around it by using a permanent marker. Take a jackhammer for breaking up the concrete floor inside the circle. Make holes around the marked circles with jackhammer every couple of inches and then use a large sledgehammer or even a small sledge with a masonry chisel to further break the concrete into small enough pieces which can be easily picked up and disposed of. Make sure while you are doing all these work you are wearing heavy boots and safety glasses, especially while operating a jackhammer. Also you must know how to properly use jackhammer or else you might hurt yourself.

  • Install discharge pipe

The good time for making an opening for discharge pipe is when the concrete around the pump is half way through being set. Check the instructions on the particular pump model for finding out what size of PVC pipe will be needed for discharging the water outside. Make the hole of the size described on the instructions. Install your discharge pipe into the hole and then connect the elbow joint to the discharge pipe with the help of PVC cement. Trim the discharge pipe to an inch or two by using a hacksaw. If possible trim it to the nearby drain. Seal the inside and outside of the pipe with silicone caulk so that it is both water tight and air tight. You can also add an additional pipe to discharge the flow of the water away from your foundation. How you connect the additional pipe depends upon the landscaping and topography features of your property. If water is automatically discharged away from your foundation then you don’t need to have additional pipe connected to discharge pipe.

  • Install sump pump pipes

For installing pipes, you need to install sump pump basin first. Installation of basin differs from manufacturer to manufacturer and also differs from type of pump model. If you are installing sump pump basin for pedestal pumps then you need to install the basin outside and if you are opting for installing submersible sump pump basin then you need to place it in the bottom. Make sure that the float is not touching the sides of the basin otherwise the float might get stuck and render the pump useless.

  • Test the pump

The last step of sump pump installation is to test the pump. For doing so, you need to plug your pump into a GFCI (Ground floor circuit interrupter) outlet and pour bucket of water into the sump pump basin. Activate the pump and see whether the pump is working properly and ensure that the inside pipes are not leaking water. Move outside and have a check whether the water is getting discharged correctly and that too, away from the foundation of your home.
