Sump Pump Turns On and Off Quickly: Follow Simple Solutions

As an Amazon Associate, I earn from qualifying purchases.

It often happens that our water pump runs irregularly and starts and stops regularly. It leads to significant wear and tears for the pump and higher electrical consumption, in addition to being able to damage the switch gear contactor. It is a common failure in a pressure group and is usually caused by a perforation of the membrane of the expansion vessel or lack of air in it.

Your installed sump pump turns on and off quickly, even if all the tapping points are closed. How can you fix this? To understand the sump pump won't turn on the problem, we would be happy to explain how domestic waterworks. It helps you better understand what is causing the problem and how to solve it. If you want to know when should the sump pump turn on?  Then you are in the right place. In this article, I'll try to cover this topic.

Causes and the right solutions of sump pump won't turn on (Problems & Solutions)

Here are the few problems & solution of the reason sump pump won't turn on:

why Sump pump turns on and off quickly

1. There is air in the system.

If air escapes at any point, the pump cannot build up the pressure entirely and thus never reaches its switch-on weight.

Consequence: The house waterworks keeps running.

Solution: Make sure that all hoses/lines are checked for leaks and sealed. If there are no leaks, check all connections. This applies to both the suction and the pressure side. Provide all links with Teflon tape to ensure maximum tightness.

2. No check or foot valve installed on the suction side

If no check or foot valve is installed, the water from the domestic waterworks runs back into the source, which the pump perceives as water loss.

Consequence: The house waterworks notices that the pressure in the line drops and switches on to build up the strength again.

Solution: Install a check or foot valve on the suction side of the pump. A check valve/foot valve has the property that the water can only flow in one direction, namely in the course of the pump. As a result, the water level and thus, the pressure cannot drop.


All suction hoses that we have in our range are equipped with a foot valve. If you use a suction hose from our range, this cannot be the cause.

3. Dirt in a valve

Dirt in a valve

If there is dirt in a valve, the water can flow through.

Consequence: The pressure drops, and the domestic water system reacts by switching on.

Solution: Remove the dirt from all valves so that they close again airtight. It applies to the following valves:

  1. Check valve
  2. Foot valve
  3. Both valves of pressure control and BRIO control

4. Drip leakage

A domestic waterworks can supply all kinds of household applications (e.g., toilets, sinks, washing machines) with water. However, drip leakage can sometimes occur (especially in showers). This means that water leaks out of the pipe, for example, in the sink of a toilet. This may not be visible to you, but it is noticeable to the pump.

Consequence: Since water seeps out of the pipe, water is withdrawn, and thus there is a drop in pressure. The switch-on pressure is reached, and the pump switches on. It turns off again as soon as the cut-off pressure is reached. A period of several (two-digit) minutes can elapse between switching on and off.

Solution: Correct the drip leakage on the connected application, for example, by using a more stable float or valve.

Maintenance of water pumps

Many of the failures mentioned above can be avoided with preventive maintenance measures. Cleaning the filters regularly, checking the excellent condition of the connections, or checking the connections are simple measures that we recommend to be done from time to time.

However, the operation of a water pump can be complicated, and given the wide variety of water pumps that exist and their various features, so is its maintenance. 

With the proper maintenance service for water pumps and pressure groups, you can get different tasks:

  • First, you have to check that the air level in the expansion vessels is correct.
  • You have also checked the condition of the panel, the pressure in the network, and the start and stop of the pumps.
  • Besides, you need to check for possible leaks or leaks in joints, keys, and pipes in the room.
  • You have to make sure that the water in the tanks, which is what comes for domestic use, is in good condition.
  • You should also check to monitor abnormal noises as well.
  • Cisterns water cut systems to see that everything works correctly and minimize risks.
  • Supervision of compliance with existing regulations and recommendations of improvements to adapt to it.

We hope we have helped you in case you have a problem with your water pump. If you have not managed to solve the problem yourself, you can request any water pump repair service from an experienced team, and you can follow our blog as well.

Frequently Answer Questions ( FAQs)

How to make a water sump pump work?

To start submersible water pumps, it is necessary first to make the electrical connection.  The height of the buoy they use serves as a circuit breaker that turns drain on and off.   

How to calibrate a conventional hydro pneumatic?

  1. Disconnect or remove the power supply to our pump.
  2. Open a water outlet until the pressure gauge reads zero.
  3. Using a “gauge” or air gauge, like the one we use to check the air in car tires, measure the internal pressure of the pre-filled tank.

How to know if the water pump burned?

The engine runs hot.  The typical sign of a potential problem with the automotive water pump can be seen or noticed from the driver's seat itself.

  • Look for leaks.
  • Unusual Sounds.
  • Loss of air conditioning.
  • Puddles of coolant.

Sump Pump Maintenance Tips and Guide 


Many homeowners tackle the problem of moisture in the basement and water damage using a sump pump - a small pump located in the basement of the home that sends water to a more suitable location, such as a patio with inclination or the municipal drain for rainwater. Sometimes the sump pump turns on and off quickly and faces the problem. That's why we tried to give a proper guideline on this topic. If you have more queries then just comment on our blog.
