It's about 4 ft. long and it fits in a 4" dia. pvc pipe in my floor. There's a rubber donut shaped bladder that fits in the pipe opening and rests adjacent to the pipe when it's installed (the bladder is not pressed tight against pipe however). Some of the shaft and motor (on top) stick out above the pipe about 2 ft. There is a side discharge above the pipe and below the motor that hooks to a pvc outlet that goes up the wall and out of the house (where the water is supposed to exit). The rest of the shaft (about 2 ft.) is below the floor's surface where the basin water collects and it sucks the water up. It works by water pressure..not a float.
There is a test button (no on/off switch) on top to manually test periodically. This may allow it to turn on or start if there is water below to be discharged. Otherwise it will not turn on when water is not present. When the on and off clicking occurs, I sometimes hold down the test button to see if I can get it to catch and stay on. Sometimes it does and sometimes it doesn't. Sometimes doing that stops the lengthy clicking.
My point is that this 60-70 revolutions of clicking on and off without engaging in a smooth running of the motor and subsequent pushing of the water up the pvc pipe (about 6 ft.) and out of the house into the city drainage system is not always happening and soon I'm confident that the motor will burn out (as before).
The pump is supposed to detect water pressure and turn on...it does not always, but clicks on and off 50-60-70 times. The pump has failed to turn on and my basement floods.
