How Does A Sump Pump Work?

First you need to know how a sump pump actually work.

Sump pump typically installed in a sump (dug) at the lowest point of the basement of your house. The work of sump pump is to remove all the groundwater by pumping it away from your house.

Whenever the groundwater rises to certain level, sump pump activates and pump the water out until the level is lowered once again.

During rainy seasons, flooding events or even water failures in your house, a good sump pump can remove thousands of gallons of water per hour easily.

Types Of Sump Pump

There are two kinds of sump pumps and these are: submersible and pedestal.

  1. Submersible Pumps: Submersible pump sits in the sump all the time and this kind is quieter than pedestal pumps. But as it stays inside the sump it makes the maintenance a messier job.
  2. Pedestal Pumps: On the other hand Pedestal pumps stays outside the sump and they are cheaper and easy to maintain. But they make much noise and you may feel it irritating.

Sump Pump Maintenance Checklist

Now comes the steps to keep your sump pump in good shape. As consequences of a failure sump pump are huge, it’s highly recommended to maintain your sump pump at least once per year.

Note: Before doing anything with your sump pump it’s highly recommended to disconnect the pump from power and wear the gloves and glasses for safety.

1. Check Your Power

Check if your sump pump is connected to powered and is turned on.

Sump pump usually use a lots of power and that’s the reason for ground fault circuit interrupter (GFCI) trips. So if you see any GFCI breaker trips then make sure to check the quality of power cord and outlet.

Make sure there is nothing around the cord that can make the cord wet.

2. Check The Basin

Basin is also important to check as it contains the water. So check if there are any cracks or leaks.

Disconnected the pump and take everything out and fill it with some water. If you see any leaking or crack then you have problem.

Change the basin or see if the old one can be repaired.

3. Disconnect and Clean The Pump

Now disconnect the pump from power source and take it out from the sump pit. Some water may come with it so be ready for that.

Place the pump on able and clean all the accessible parts of dirt and debris. If you can then remove the grate from the bottom of pump and clean it.

Clean all the pump area with cloth and make sure not to destroy anything. Check the product manual to know how to clean the pump more effectively.

Check the manual to know if the gear needs oil or greasing.

Mostly pumps can be cleaned with garden hose, paper towels or a bristle brush. Check the manual to learn if your pumps can be cleaned with any of these too.

Also check the Check Valve, most of the time it also cause failure. You can test it by pushing it up and down and you should inspect the Check Valve once a year.

If the Check Valve is freely moving and does not stick then you are good to go. If not replace the Check valve.

4. Test Your Pump

Now fit the pump in sump pit and connect the power source to the pump.

After that pour a bucket of water into the sump pit. If the pump turned on automatically and pump the water out, then everything is fine.

But if it’s not working then maybe the float is not in place. As sump pump use a float to detect water and maybe while cleaning or because of dirt the float is stuck.

So try to loosen the float or clean the dirt around it (if you see any) and then check again, it will start working.

5. Check The Drain Pipes

This is also another common problem for a failure sump pump.

Sometimes the pipes filled with debris or dirt and backed up. So pump fails to through the water out.

So take hot water and pour it from the upside and dump the water from downside of the pipe. You can repeat the process 2-3 times if water is not coming properly.

If water comes without any problem then your drain pipes are ready to work.

Make sure to make your pipes blockage free by cleaning the dirt and debris from the pipe.

6. Test the Backup Battery

Also check for the backup battery after every 6 months.

You can test it by disconnecting the pump from the main power source and then pour some water into the sump pit.

If it starts everything is fine otherwise you need to change the battery backup.

For more maintenance of battery backup sump pump, check the owner’s manual and follow the instructions written there.

7. Check For Oil Leaks

Sometimes oil can come with ground water, but sometimes there maybe a leak on the body of your pump.

If you see oil in your sump pit, check the body and all the areas from where oil can be leaked. If you see any leak try to stop the leak.

If the leak is big, then ask service guy it can be repaired, if not then replace your sump pump.

8. Test

Now after performing all the above steps you can still run a test flood to double check if everything is working fine.

Just fill your sump pit with water by buckets or run a hose. If pump kicks and start pumping the water out then everything is right.

When You Need To Replace Your Sump Pump?

Well nothing lasts forever and water tools are also need to be replaced by time.

Your old pump could fail due to old age in the middle or major rain. So it’s really important to check for the lifespan or your pump and replace it before it’s too late.

As per experts, submersible pumps near around 6 to 15 years and a pedestal pumps last near around 15-30 years.

But it also depends on the area type too, if you are living in a wet area or heavy rained area, then pump can stop working before that time.

So check the sump pump’s documentations and see how much years it can serve and also take the advice of a professional or service guy.
