Constant water flow into sump pit

Constant water flow into sump pit. A high water table usually causes a constant overflow into the sump pipe. Pipes that leak and burst pipes cause the flow into the sump pump as well.

Discharge lines that have been partially blocked may also be causing the flow of water into the sump pump.

My sump was overflowing as the water kept entering it, and the flow of water in the pump wouldn’t stop either.

I thought the sump pump would reach its limit and the flow inside the sump pump will stop soon, but the sump pump kept receiving water, and the flow remained untouched.

I was worried about the sump pump flow and contacted a plumber.

The plumber fixed the flow of the sump pump and even helped me write this troubleshooting article. My flow was fixed by him, and I can actually fix the flow by myself now.

Constant water flow into sump pit

Having your sump pump burn out prematurely is not great. The burning of the pipe is actually caused by the constant flow of the water.

The float of the sump pump may be stuck at on, and that’s why the water doesn’t stop. The water may be running because there is a leakage somewhere.

A high water table is something that goes matching with the flow of water, meaning the high water table is causing the flow.

The discharge lines that are partially blocked are what’s causing the lines to be flowing. Burst pipes are pretty common. Read more below!

On switch

The first thing that should be checked if the sump pump is letting the water flow or is flowing with the water itself is its valve.

The sump pump has a valve that needs to be turned on for the flow of water, but it sometimes happens that the user turns the valve of the sump pump on, and then vice versa is actually forgotten by the user.

Check the sump pump and make sure the valve of the sump pump is off. The off switch condition will be easy to notice in the sump pump pit.

If you see that the float switch in the sump pump’s pit is on, then the reason for the water in the sump pump is the float switch. Check the float switch of the sump pump, and turn the sump pump off by turning the switch.

Broken float switch

The float switch staying on is one float switch problem, but the other float switch problem is that the float switch is broken or the float switch has gone faulty.

The broken float switch can also be faulty. There can be a leakage in the float switch.

The float switch may not be left on, but the float switch will still give water even in its off state because of the float switch faults and leakages.

The float switch, when flowing with water in the off state, will cause the pipe to burn. The pipe of the float switch will be useless, and even the pit will become faulty.

Check the float switch and see if it is flowing water in the off state. If there are leaks in the float switch, make sure to fix the leaks. The faults in the float switch should be checked, and the float switch should be replaced when broken.

Discharge lines

discharge lines

The float switch was not on, and there weren’t any leaks so that the water would stop, but the water didn’t stop because of the discharge lines. The discharge lines are important parts of the pit as well.

The discharge lines discharge the flow from themselves into the pit and let the pit get the flow from the sump pump.

Sometimes the sump pump has discharge lines that are not working fine. The discharge lines of the sump pit may be partially blocked.

The partially clogged sump pit’s discharge lines are the lines with the disrupted flow, pressure builds, and the lines transfer the water to the pit, and in the end, the pipe burns.

Check your line and make sure they don’t have partial clogs in them.

There shouldn’t be full clogs in the sump pit either. If you find partial clogs in the discharge lines, find a way to open the partial clogs.

The same goes for full clogs. Use baking soda to get the discharge lines free from any clogs. The clogs in the discharge lines can be removed manually by using other chemicals and tools.

High water table

Sometimes the constant flow of water is not because of the parts of the sump pump being faulty or loose. The fill valve may not be faulty either.

The fill valve and other parts of the pit aside, there is still the flow of water in the bit, even without the parts being faulty. The water table of the sump pump can be too high, and because of the height, the water keeps flowing.

The high water table is a big factor in water flow. If you have water flowing without the parts of the sump pit, then check the water table.

Raising the sump pit in case the water table is set too high will take care of the flow in the sump pit. If the high table doesn’t work, then there may be the need for an installation of an extra sump pump.

Burst pipes

burst pipes

If the high water table was not the reason for the water flowing in the sump pit and even the discharge lines were not causing the water flow either, then the pipes of the sump pit are responsible for the flow of water.

The pipes of the sump pump can burst, and the bursting cause a new path of water to open, and through this new path, water flows very fast. Burst pipes are a pretty common reason the water flows into the sump pit.

The pipes bursting don’t mean that the pipes have completely burst, but the pipes may have leaks and holes inside that are causing the water to leave from there.

If you have pipes that are damaged, then fix the damage on the pipes so that they won’t burst. To fix the water flow in the sump pump, replace the pipes.

The pipe that is leaking can be the sewer pipe, and even the sprinkles in the yard can be the ones that have burst and are making the water flow.

The sprinklers and the yard pipe will require replacement, and the sewer pipe should be replaced by a professional.

Mechanical fault

If the button is on, the lines are not clogged, and the setting of the sump pump is not wrong, then there can be a mechanical fault in your sump pump.

The sump can be running even when the pit is dry. The issue with mechanical fault is different from drainage.

The mechanical fault matches the float switch, but there can be other mechanical faults in the sump pump and the pit too.

Check if the sump pump’s mechanical faults can be fixed by you or not. A professional should check the sump pump if there is a mechanical fault.


Having a faulty sump pump can be training. The sump pump usually has drainage issues and the water through the sump pump keeps flowing into the pit and causing the pipes to become faulty.

An expert should deal with the drainage and mechanical issue in your sump pump. Thanks for reading!
