How to Test a Pump Float Switch

[@NFPowercat78]

Can't see the settings on the multimeter or where the leads are plugged in. To be helpful to beginners this would be essential. Also cannot tell what prongs on the piggy back plug you are referring to. Thank you for the video prompting further research.

[@sassczar1760]

he put it in the lower flat prong and the lower slot on the back side.

[@kozmikkev474]

Hold that plug so we can see the holes, man I have no idea which prong you are talking about holding it sideways. large prong,small prong or round prong, why not identify it....useless video

[@LygerTheCLaw]

this test doesnt prove either can carry the needed current or that an old float switch has been compromised by arcing. i have a float that tests fine like this, but it won't turn on my sump pump, it's about 2 years old and sees thousands of cycles a year. i can jiggle the float and the pump will turn on, but these often time fail when using 10a or more in current(their upper limits are usually 10-15amps) the bigger your pump is, the shorter their life is, better to convert this to a low amp relay switch at that point.

Might want to show the test lead config on the piggyback switch before testing, you couldn't really clearly see which plug outlet you plugged into.

[@Jack-Surreal_Panes]

Tested mine. I had nothing down but resistance up. I Second float, nothing up or down. Pump float low reading down but when up, I high.

[@travisleddy6887]

Exactly what I needed. Thank you.

Glad it helped!

Hi. My alarm in on but the water isn't touching the alarm float. Please help.

[@Punny1234]

I think he had the meter hooked on to the hot prong and not the neutral one.

[@robtheisen5844]

Great video! Show us plumbers how to dust off the old Multimeter and put it to good use! Keep the videos coming!

[@RCworstwater]

We've got two more multimeter videos coming out next! :)

[@erinjohnson9873]

Total newb here… but is the float inside the septic tank? How do I get at it? Do I actually have to climb inside the tank? 😮

[@christinemarkley]

Very helpful, thank you! Is replacing the float switch something a DIYer could do?

[@RCworstwater]

Yes, absolutely!

[@richardsatterfield4222]

Where do u set it on the ohm meter

[@natetolbert3671]

Pro tip: If you do dot have access to a multimeter, a test light should work just as well.

[@RCworstwater]

Good Tip!

[@ElonMuskX]

What about a power bleed problem in the float. Mine test great but down is send some power through . Does the float need to match the motor HP???

[@andymclemore6193]

Wish I could see which holes you were plugging into, if so it would be a great video

[@linuxcaffe]

.. words .. :) keepit up! I enjoy / learn from yer vids, thanks

[@RCworstwater]

Thanks for watching!

[@BenjaminMaciel21000]

Mine is backwards right now. I just plugged it into the contactor and When I flip my pump switch is up-- its turning on. And when I turn it down-- its off. Any ideas?

[@RCworstwater]

Sounds like you have a normally closed float or contactor.

[@MrRuss58]

when my i move my up inside tank it trip the gfci..any idea ?

[@functionalvanconversion4284]

The breaker at the house subpanel was left off causing a high level water alarm to be triggered (when the tank overfilled). I manually turned the pump on and then tested all three floats, but for some reason the on/off float won't turn on the pump. I tested it for continuity and it works when flipped (it's only 1 year old along with pump and all floats). I tested the switch as well and it works. Any ideas? Thx

[@JonnyA365]

Could've gotten the connections wet when tank overfilled maybe a short in pump wire

[@functionalvanconversion4284]

@@JonnyA365 when I lift the on/off float with a hook it sets off my ohms meter (reads continuity). Low level float and high level float still set off the alarm when I lift them with a hook as well. The pump also runs manually. Do you still think there could be a short in this case? If so I'll take the wire junction box apart as I am testing from the control box.

[@TheAngelin2000]

I'm glad i got to see this. i see this test. 1 was doing the wrong way wrong way

[@maramacs1254]

Hi, thanks for the video. I have a problem with the solanoid float system for a solar hotwater system not responding and suspecting the float switch. There is a voltage running through the float switch whether the float is up or down the magnet shaft in one orientation, but if I turn the float around then there is no voltage through the switch whether the float is up or down the shaft. Does this mean there is a problem with it and if so can I fix it or do I need to get another one? Thanks heaps.

[@jorgemac211]

I have 3 floats, 2 to control pump and one is the alarm. which type I should get in regards of amperage and if the 3 floats are normally open? tks

[@RCworstwater]

That depends on your pump's amperage. Give our experts a call: 855.329.4519

[@556nutt]

Kinda figured that was how to test one but your video was helpful to see it. Thanks

[@RCworstwater]

Glad it helped

[@JamesSathre]

Thanks for making this video! I was able to test my own float switches at home after watching it. All were working perfectly, but I didn't know anything about float switches before this video.

[@RCworstwater]

Great job!

[@matthewdavar]

This video is very useful. Thank you.

[@RCworstwater]

Glad it was helpful!

[@aaronalquiza9680]

Very informative! Thank you!
