20 Most Recent Flotec 1/4 Horsepower Sink Pump System Questions & Answers

It sounds like the float is stuck. Try pulling the wires coming out of the tank(shake them a little) and see if that will free the float and shut the pump off

These units have a "check" valve on the discharge pipe which is a one way flow valve. If debris or sludge get caught in the check valve it gets held open allowing water to backflow. Remove and clean or replace the check valve.

Please review the below web page, it is a troubleshooting guide for your pump. I did not see anything on an internal fuse on your particular pump.http://www.flotecpump.com/ResidentialPage_resource_ts_utility.aspx

One thing I would do is to make sure there is not a check valve installed backwards. Thank you.

If the pump is only pumping for a few seconds at a time it may be a problem with the control board. On two of mine, the 10mf 100v smd capacitor came loose. Resoldered and potted with hot melt glue. One of them is working with the other yet to be tested. Don't recall what the exact symptoms were, only that it wasn't continuously pumping water while submerged.
Unit is oil filled so should be dismantled in the upright position.

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.

Most pool water from the season before usually contain a lot of sediment, leaves and things like that. These pumps were not designed for continuous use, like draining a pool. Either it has a bunch of junk in it, or the motor just gave up.

flotec intellipump does not work,new,out of box.does not detect water under any conditions.as we have flooding in r.i.,i thought i got lucky to find this pump in home depot in dartmouth mass.now i find i have a basement full of water,and a hastle trying to get my money refunded.

If it is not Powering Up Check the Fuse / MCB first

Hi,
Either the float has gone bad or the float is stuck...
give it a kick or a slap and see if that dislodges the float...
If the pump continues to run, open it up and make sure the float has dropped...if it has then the float will need to be replaced...

hi, draino and all those sorts of products only make it worse they will help the blockage solidify best way is to run hot water through the system even if it is boiling water from the kettle and a little bit of a pump with a plunger should do the trick

Please find above a manual for your unit.
You obviously have a clog (partial) in the drain line. The sump pump pushes a lot of water at one time and the clog is making the water back up into your sink. If the pump wasn't going off so often, I would suggest using an enzyme drain cleaner such as Draincare. Problem is, it takes overnight to work. You may have to snake the drain line to get it cleared out in a short amount of time. The sump will have to be turned off while this is done. Good luck.

It actually sounds like you really need an entire nw unit. I fear that this existing one, is beyond repair, you would have to remake the connections through the grommet, and the grommet too. I guess you could remove it and try and refurbish it. replace the wiring to the motor. reassemble and reinstall.

Start by checking float switch

pull the pump you may have a broken pipe in the pit.

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

Even new pumps have faulty parts. It could be that the foot valve is defective.

No, this pump does not natively turn on and shut off based on pressure. You need to add a pressure switch and tank. Flotec has the manual for the FP5172 here: https://www.pumpagents.com/pdf/FlotecPumps/Flotec-FP5172.pdf . I hope this helps. Cindy Wells
