desired location of the cylindrical body 3 using safety screws 53 to determine the desired height of erection as shown in fig3 an extension brake 49 made of a rigid material such as pvc abs plastics metals etc may be attached the cylindrical body 3 by fastening means such as corresponding treads rivets screws adhesives 43 an sensor extension 51 made of a light and or buoyant material such plastic foam etc is fastened to extension brake 49 using fastening means such as water resistant glue 23 and safety screws 53 as shown in fig3 making the pop up sewer cleanout cap sensor more sensitive to even a slight rise of sewer water lubricant 25 is poured into a reservoir 17 thru aperture 21 the space between the cylindrical body 3 and the cylindrical housing 1 forms the reservoir 17 which holds the lubricate 25 as shown in fig3 cylindrical body 3 is then pushed in a downward direction until top brake 7 meets cylindrical housing 1 and sits in the recess 35 held in position by a brake seat 41 the recess 35 allows my invention to have a flat surface as shown in fig1 a notch 37 also allows a pin 39 made of the same material or a rigid material such as a metal to be located below the flat plain of top brake 7 as shown in fig3 a lubricant 25.
