Small Electric Pump for Draining 

 Seepage from a Cellar 



HOUSEHOLDERS living on low 

 ground are continually troubled 

 with water seeping into the cellar. The 

 condition is seldom easily remedied, for 

 not even concrete floors and walls are 

 successful in stopping the water's in- 

 roads. For cellars so afflicted a new 

 electric seepage pump is proving highly 

 effective. The idea is to make a tank- 

 like hole in one corner of the cellar into 

 which the water can seep in preference 

 to working its way up through the con- 

 crete of the floor. 



The motor used with this device has a 

 vertical shaft, and is located on the cellar 

 floor. The shaft is connected with a 

 centrifugal pump under water in the 

 hole beneath. The contrivance is en- 

 tirely automatic in operation. A float 

 sets the motor going when water has 

 collected to a certain height and shuts 

 off the current when a sufficient amount 

 has been pumped out. The hole, being 

 at a much lower point than the sur- 

 rounding cellar floor, serves as a Mecca 

 for all the ground-water beneath, leaving 

 the floor dry and sanitary.
