TIPS TO KEEP A SUMP PUMP DISCHARGE LINE FROM FREEZING

What to do to prevent the pipe from freezing

 

the pipe is frozen
Frozen Garden Hose and water pipe connection

Well or borehole of a country house, as a rule, is located a few meters from the house. Sofmetimes, the well is made in the basement of the house, but even then the measures against freezing of the pipeline must necessarily be observed.
If the hose of the a sump pump discharge line from freezes, the pump will work harder and eventually will fail due to overheating. This means that it will not be able to drain the water that accumulates around the foundation.

 

Typically, the water in the pipe does not freeze in the underground section of the pipeline, but at the border with the ground, buried in the yard, then the crystallization goes through the air section of the pipe. Another “weak” section of the pipeline is located on the border above ground level with a downward slope. Because of the inevitable in this place of a draught along the contour of the pipe, to get rid of which is quite difficult.What can be done with a frozen pipe :

 

Passive precautions A SUMP PUMP DISCHARGE LINE FROM FREEZING

pipe from freezing
1 /The material of the supply pipe itself should be heat insulating. It can be polyethylene, polypropylene, metal-plastic. Metal pipes specialists do not recommend using.
2 /It is desirable to choose a larger diameter of the supply pipe. The larger the diameter of the pipe, the greater the volume of water in it, the thicker the wall of the pipe (additional insulation), the longer will cool the water to freezing point.
3 /The pipe should have a slope to the well or well, and must be insulated. The slope should not be steep, but continuous, so that the force of gravity will help water flow (standing water in the pipe is more likely to freeze)
4/All places where the pipe passes through walls and ceilings (floors, ceilings, sump pressure pipe and suction part,) must be sealed ! To avoid the formation of even the slightest drafts of cold air in these places.
5/ It is forbidden to pour automobile antifreeze into the sump. If there is no possibility to put the pipes outdoors it should be well insulated and their at least occasional heating (heating cable, heat from the house, HTW or heating pipes) should be envisaged.

Active precautions.

 

  • pipe from freezing1/ It is necessary to provide easily detachable pipe connections at the exit from the well or borehole and at the entrance to the house or basement, for possible inspection of the underground pipe mouth and removal of ice plugs.
    2/ In severe frosts, if you are at home, pour, i.e. turn on the water, at least once every two hours. Then you only need to heat the pipe, turn on the heating cable, once a day – in the morning.
    3/ The best active protection is to run the heating cable through the supply pipe. The sump pressure pipe and the suction part should be insulated for frost protection.
    4/ If submersible pumps are used, a small hole can be made in the pipe (1-3mm) 3-5cm from the pump for constant water flow. The flowing water will never freeze. Unfortunately, when using pumping stations it is impossible to do this.

  • Conclusion.

  • As practice shows, compliance with only passive measures against freezing of pipelines ensures their trouble-free operation up to 20-25 degrees of frost. If all measures are observed – in any frost.
