A Step-by-Step Guide to Replacing a Sump Pump

The process can seem dreadful, but always remember that with ample knowledge and a reliable guide, you will definitely go through the process with ease.

Gear up

Before starting the process, you have to prepare yourself and all the things you need. It is only right to get into gear, wear something you are comfortable with. Wear clothes that you deem to be okay to be dirty after the process and one that you can move around with. A jumpsuit can be a good choice for this.

On the other hand, you also have to prepare things that you may need in the process. You should have the new sump pump, discharge pipe, composite or plastic shims, and check valve ready. Alongside this should be pliers and screwdrivers as these tools are essential to attaching and detaching parts of the sump pump.

Prepare your Area

As always, make sure that you secure your safety first. This is why you have to start by disconnecting the sump pump to be replaced from its power source. Take off any sort of cover placed on top of your basin and if possible, shut off the main power source where the sump pumps are connected. It is essential that you cut any connection to electricity to prevent injuries and accidents.

Detach the sump pump

At this point, you have to check the PVC pipe material that is holding the sump pump and the discharge line together. From there, you can measure the amount length of the PVC pipe material you need for the replacement. You will have to make sure that you get an estimate that will be enough to provide you with enough room to move. Once you have come up with a certain measurement, you can then start cutting the discharge pipe using a hacksaw. Remove the sump pump from the pit.

Create a new line

Now that everything is ready, you can then go prepare your new line. You do this by getting a new PVC pipe material and cutting it according to the length that you measured to be a good length for your replacement. Sometimes, people go for 1 ¼ or 1 ½ inch in terms of measurements. You can also refer to the old PVC pipe material measurement, but it is recommended that you stick to your new measurement especially if you have altered it to make way for more space. A good concept to remember is that it is always better to have a PVC pipe material that is too long rather than one that is too short. An excess can easily be cut off while a shortage can be hard to work around.

Connect the sump pump and pipe

Now that you have your pipe ready, you can then go to the process of connecting your pipe. Start off by finding the discharge outlet in your new or replacement sump pump. Secure this with a male adapter. A common tip by many would be to utilize a PVC glue or purple primer to attach the pipe to the male adapter. After application, make sure to give it a few minutes to dry.

Position the sump pump

After attaching the discharge pipe to the sump pump, you can then proceed to make sure that the sump pump is positioned properly. Check and ensure that the sump pump is has a well-organized and untangled wiring. Position it in a way that it is not leaning on the walls of its basin or too close to the float switch or back-up sump pump.

Level the sump pump

Checking that your pump is positioned properly is one thing. Another thing to make sure is that your sump pump is stable and leveled. Failure to do so may cause the pump to rock on the basin’s bottom. Hence, you should make sure to secure it at a good level. You can use shims to place under the bottom of the pump to help level it.

Mind the float switch

Your pump’s float switch should be checked properly before you proceed. Check and guarantee that the float switch is free of obstructions and is placed in a manner where it is to work properly. If you place the switch in a position that is lower than usual, expect your sump pump to operate continuously. On the other hand, if the float switch is placed higher up than the recommended level, it will have a hard time catering and adjusting its expected operating power and performance to the actual level of the water needing to be pumped. This is why making sure that the float switch is at its proper level is critical.

Attach the discharge line

Now that everything is almost set up, you can go ahead and mend the discharge line. Adding or installing a check valve is ideal. This is a good connector for the sump pump and discharge line because it stops the water from leaking or seeping into the sump pump the moment it is switched off. Some sump pumps have one installed or included, but it happens to be excluded from your unit, you can always buy one outside and have it attached to preserve or prolong your sump pumps’ lives.

Plug the sump pump

Now that everything is ready, find a reliable and well-functioning outlet. Connect and plug the new sump pump into it and then proceed to testing of the unit. Once the sump pump is powered up, you can try powering it up and putting it to use. Collect about five gallons of water in a container and pour it into the sump pit. Observe how the pump operates and make sure that the pump is effectively pumping out the water of the pit and that the discharge line is smoothly directing the water to your desired drainage station.
