    There are no obstructions around the float / ball. I will replace the ball and see if this works. Why would it not be the mercury switch????

    Pump was fixed, the breathing pipe was an obstruction. Simple. Thanks

The float has a mercury switch and that is what will make it turn on and off.  this ball sounds like it is not working correctly.  you will have to replace it.  just the ball

Its supposed to be controlled entirely by the float switch in the pit, etc. Its not uncommon for the pump to work or stay on even if the water level drops because the float can get hung up on the pipes, side walls, debris in the pit etc. You need to eliminate all those issues. Other issue is the float switch my be bad, hanging up or need resetting to the proper height etc. If its still a problem try replacing it with a water sensor switch instead.

Sump pump


I am presuming you're asking about a basement sump pump, the kind that keeps your basement dry. Well, those things are not meant to run all the time. They are usually triggered by a float valve. That is a device that moves according to the water level in the sump (in other words, the hole). When the water gets high enough, the float activates a switch, the pump kicks in, the water is flushed away, the float falls and that turns the pump off until the cycle starts all over again. The frequency of the cycle depends on how fast the sump fills itself. I have one that kicks in five times a minute. Another might have a much longer off time. But don't be worrying about yours not being on all the time... that is how they are supposed to behave. Of course, if you have water flowing out the top of the sump, that is a sign things are not right with the pump. Then you really need help.

Do you have a check valve on the discharge line going to the street? This would prevent the backup of water back to the pump making it want to come back on. Things you can try, can you make the holding tank under the sink larger so more water need to be present before it comes on? Also have you tried to put a vacuum break on the system? You can make one easy by razing the outdoor discharge pipe two to three feet high just as it comes out of the house, place a upside down "U" at the top that flows into an open larger pipe that take it to the street. This way if you are getting a back flow you will only get the amount of water between the pump and the upside down "U", however if it was me I would be sure there is a check valve close to the pump so a back flow cannot happen, you can get them at your local hardware or pluming store.
Lastly, the float is adjustable in two locations, one is the location of the float when the maximum water level is reached (turns on the pump) and at the level of water where it turns off the pump, giving a buffer area so if there is flow back it takes more to turn the pump on and less to turn it off, try playing with these two levels on the float.

1 inch of water is probably not enough water to set off the pump. The water level must be high enough to float the switch ball beyond 90 degrees of level before it will activate the pump. The pump will not evacuate all of the water there will always be some water left in the tank this prevents the pump from a dry start.

I have a Flotec pump model #FPSC4550A that will not stop running even though the float falls down. Any ideas?


Sounds like the contact inside the float is stuck. It can be corroded and not letting the circuit open and that will keep the pump running.
If it had been fine but just started doing this, that is what I'd check. If someone could have accidentally wired it incorrectly when they were trying to fix it, perhaps they accidentally bypassed the float switch and have it "running hot" all the time.

Flotec website shows several submersible sump pumps, and pump types:
http://www.flotecpump.com/asp/productapplication.asp?AId=28

Click product, then click on 'parts and literature' to access manual
Here is a Flotec manual:
http://www.flotecpump.com/pdf/FP525%2811-1-06%29.PDF

Manual for this type of sump pump says:
Quote from manual: Automatic float switch is sealed and factory adjusted for
most home sumps. Turn-on water level is 10" - 12" above
pump base. Turn-off water level is 4" - 6".

The manual also says that running the pump when dry will ruin the seals.
This implies that the water level setting is set so the seals will not be damaged

You might be able to dig the sump deeper, but I don't know if that meets your objective.
