How to Seal a Crack in a Suction Pump

suction pump is an important component in plumbing systems since it helps keep the plumbing system working properly. Moreover, most suction pumps are necessary for the discharge of waste water from your house to the sewage system. Suction pumps greatly rely on the difference of pressure of the pump and its environment. In most cases, the pumps generate a low pressure so that it can suck liquid into the pump and exude it as waste. However, there are times when a suction pump stops working properly and this affects the sucking capability of the pump. A suction pump stops working if it has a crack in it and if you happen to experience this particular problem, then here is a DIY procedure on how to seal a crack in a suction pump.

 Materials Needed:

  • Industrial sealant
  • Applicator or stick
  • Screw driver
  • Rag
  • Industrial oil

Step 1 - Assess the Pump First

It is important to assess where the leak or crack in your pump is located. To do this, turn on the pump first and look for any leaks in the tube or in any parts of the pump itself. Once you have located the crack, turn off the pump and unplug it. Wipe the area that is leaking with a rag and  mark the area using a pen.

Step 2 - Remove the Tubes

In most cases, the part of the suction pump that always leaks is the tube so it is important that you remove the tubes first from the pump. To do this, use a screw driver to unfasten the screws that holds the tube to the pump. Clean the area where you have just removed the tube with a dry rag. Moreover, assess the tube to determine if it needs replacement or not. If not, clean the interior of the tube with a solution of soap and water and let it dry. The suction pump usually develop cracks if there are a lot of debris that adhere on the insides of the tube thus it is important to clean it out first before you apply the sealant.

Step 3 - Apply the Sealant on the Crack

Using an applicator or a stick, apply an industrial sealant on top of the crack. Make sure that you apply ample amounts of the sealant on the crack so that you will be able to stop the leak on your suction pump. Make sure that you have covered the entire crack with the sealant before you let it dry for several minutes or hours depending on the instructions of the sealant.

Step 4 - Put Everything Back

Once the sealant is dry, you need to put everything back in order. However before you connect the tubes to the suction pump, make sure that you apply industrial oil on the hardware of the pump first to make it more efficient. Test the pump this time and check if there are any leaks. If there are, then assess if there are other cracks that you have overlooked or if the tubes are tightly held to the pump.
