My R520-T7 pump hums but will not turn on

sounds like a jammed or detached impeller, located at the bottom of the pump motor. Repairs are unreliable and replacement is inexpensive ($130 for a comparable pump) recommend replacing the pump.

My 912-005 sump pump will not kick on. when plugged in it hums like it wants to work. We tool the cover off as i expected top see a float but we cant see it. Have never dealt with a pump before. ...

When a pump hums instead of working, there are two possible things.
1) Something stuck inside pump impeller. See if there is rust or debris. Move the impeller and see if it rotates freely. Unplug electrical device before working on it.
2) The pump winding has gone bad and pump will never work again.

Motor hums attemps to turn but does not

If motor hums and does not rotate, the motor winding is bad.
Motor is overheating and will stop humming and it will not work again.
30 years ago, motors were rewound at local electric shop.
Today the copper winding and steel parts are recycled or thrown into landfill.
Check warranty papers and then buy new pump.

I have to tap on pipe to get pump to come on when water is pass float

The first thing I would do is unplug pump and disconnect discharge pipe. Then remove pump from pit and check float switch to see if there is anything catching on it that would stop pump from running. While you have pump out of the pit you can wash it off and spray water around base to clean inlet to impeller, also clean float assembly. Install pump and hook up discharge pipe and plug it in. When you put the pump back in the pit make sure that it is sitting so that the float is free to move. If you don't want to remove and clean pump then make sure that float is free to move where it's at. I hope this helps you. Thanks

The pump has gotten where it pumps a few seconds and stops ,I thought maybe it's low on oil

Most sump pumps are sealed so they have no way to add oil. I would see if your pump discharge line has a check valve installed in it.It should have a check valve installed so that waste can only flow away from pump.Otherwise the pump can cycle for a short period,shut off and have water in vertical pipe flow back into sump basin causing pump to cycle again. Also if your pump does have a check valve in it make sure that it doesn't have anything caught in it that would stop it from closing completely. Some pumps have a check valve installed on the pump. It is also possible that you may have something caught in the pump impeller. you will need to remove pump to inspect the impeller. Hope this helps you. Thanks

Will drain water

110-120v motors are designed to run only one direction they cannot be reversed a more likely solution is that something is blocking the line for water to flow out or that the impeller is not turning try taking the hose off the top (be careful not to get wet ) and turn the pump on to see if water comes out top if it does line is blocked, if not time to get new pump

My sump pump hums, but the propeller doesn't turn.

yes the pipe is the same size all the way through, if it is just humming and there is nothing blocking it, the motor could be going bad and doesn't have the power to turn the pump,, did you check to see if the shaft could be bent> like as if a rock may have gotten stuck but broke loose before you took it apart
