How to Replace a Sump Pump?

December 16, 2021

A sump pump is a vital and integral part of any cavity drainage system, and a must have if you are looking to keep your basement dry.

So, if your sump pump has packed in and a repair looks to be off the table, then it could well be time to replace the sump pump with a new one that is poised to work and protect your basement.

So, if it is time for your sump pump to be replaced, then here is the process that will usually be followed in order to successfully replace a sump pump.

Can I Replace a Sump Pump Myself?

Whilst the technical answer here is yes, we do not recommend that any private owner of a sump pump undertake any kind of repair work or replacement action unless they are qualified in sump pump installation, maintenance and repair.

How to Replace a Sump Pump

These are the steps that should be followed when it comes to a sump pump replacement.

We want to remind you before this list once again: We do not recommend DIY sump pump replacement or repair. Please get in touch with a qualified engineer, and we will be happy to help.

Step One: Shut Off the Power

Shut power off in your basement, and make sure that the sump pump itself has no power running to it and that there is no risk of electrical fault or shock from handling the sump pump as its being replaced.

Bear in mind though that whoever is fixing or replacing your sump pump is still going to need an adequate source of light, so make sure you can run a decent lamp or other form of light in the room itself whilst the work is being done.

Step Two: Disconnect the Old Sump Pump

Firstly, the sump pump’s cover will have to be removed, so that access can be made to the inside of the pump itself.

Once the cover has been removed it’s time for the old sump pump to be removed. This can be done in one of two ways.

One option is for the pump to be disconnected from the discharge pipe with the use of a wrench. This way keeps your discharge pipe intact, and removes the pump only. The second option is to use a saw to cut the discharge pipe and remove the pump by literally taking it (and a tiny portion of your discharge pipe) out of your drainage system.

This second option might be preferable if your sump pump is too stubborn to loosen off of your pipes, or if the choice has been made to replace the discharge pipe itself anyway.

It is important to remember though that if the discharge pipe is cut when removing the sump pump, that a measurement will need to be taken so that the extra length between the pump basin and the discharge pipe can be made up with additional piping.

This is usually easily done, and with a clean cut your pipes can be easily connected. Sump pumps use common pipe measurements, and most fall into a category of either 1 ¼ inch, or 1 ½ PVC piping – so it will be easy enough to connect to the rest of the discharge pipe with a connecting valve.

Once all that is done, the sump pump can be safely removed from the sump.

Step Three: Install the New Sump Pump

Once the old sump pump has been removed, the new pump can be inserted. Care needs to be taken in handling the pump as if it’s jostled too much then calibration settings and internal connections could be compromised, making the new pump faulty before its even inserted.

Once the new sump pump has been lowered into the basin, it will be time to connect it to the discharge pipe.

As previously mentioned, this should be easy enough, but it will be important to make sure that any connector valves or other possible holes or cracks are sealed with a PVC quality glue.

Once your new sump pump has been lowered into the sump chamber itself, it’s important that the pump itself is levelled correctly and well secure in its place.

It should also be made sure that the pump itself isn’t leaning against a wall, that the wiring is neat and not at risk of coming loose, and that all the fittings are in free moving order.

Before you turn on the power supply to the pump itself, it would be wise to test the position of the float switch to ensure that it operates in the way that it needs to.

If the float switch can’t work as it needs to, then it will need to be checked to make sure that it isn’t stopped by obstructions or malfunctions.

Step Four: Test Your New Sump Pump

Once the power has been returned to the basement and your sump pump once again has a power supply, its time to make sure that the replacement sump pump works in the way that it should.

An easy way to test if a sump pump is working is by filling a bucket with water, then pour it into your sump pumps collection chamber. As long as your sump pump is capable of removing the water introduced into its drainage system without fault (and that the sump pump engages at the correct level set in the basin itself, and that the float switch works) then your sump pump installation can be deemed a success.

All that will be left to do is an inspection of the connected pipes and valves to ensure that no leaks are present. If there is a leak, it will need to be treated with a proper sealant, but otherwise the sump pump replacement will be complete.

Once Your Sump Pump Has Been Replaced

If you have had your sump pump replaced it’s important that you follow up its replacement with regular health checks and maintenance to ensure that your basement avoids the risk of a flood.

You can consult with our engineers to arrange a visit and ongoing maintenance schedule that works for you, with follow up visits spaced out and arranged to keep your sump pump in perfect working order all year round, avoiding a costly and devastating flood.

This is important if your sump pump has been installed or replaced by a trained engineer, and can often be arranged following the installation itself – if the replacement has come from yourself or another third party, however, a follow up health check is even more important.
