The contacts have a ultra thin coating of silver plating when the switch is new. Ants will commonly get in between the contacts and then get fried! They are attracted to ozone that is created when the contact spark. Rather than first useing sand paper, try using electrical contact cleaner. Turn off power! Spray several times. Spray it on a very thin piece of card stock paper, then run it through each of the 4 contacts, while manually closing the contacts, as you spray more cleaner through the contact points. Let this dry well for at least a half hour. Turn power back on, and see if this will work. If no luck, go to 660 grit sand paper, or finer if one can find it. Auto paint supplies has very fine sand paper.

The best explanation on anything i’ve seen and heard

This was very helpful. You talk slow, but thanks to the 1.5x KZfaq speed adjustment I was able to retain my sanity. I kept thinking the contacts were normally open, now I understand. Thank you!

VERY helpful! The pressure switch on my air compressor is acting up. Now I can take it apart, and figure out what is wrong. Thanks very much!

I understood Your explanation so much actually made me fix a problem I was having with my pump. Thanks a lot 👍🏽

Thank you, thank you, thank you, thank you!! I got my girlfriend's pump working again since it was intermittently pissing water at very low pressure, and when the pump engaged it was like a fire hose.

Thanks only had to watch the first two minutes of your video to get the answer I needed very helpful thanks

This is amazing illustration. Thanks and greetings from Sri Lanka. Recently I find the pressure pump starts almost the flow stops and in the gauge it is noticed that the pump starts only when the pressure drops to zero. I messed around the two nuts but no change. I am sure you have a good piece of advice for me. Thank you in advance.

the switch on the side for me helped when i had to prime the pump or if your having issues from pump to well. I prefer the switch because if you run out of water at the well or busted line the switch will shut off your pump when it goes below 10psi, thus not burning up your expensive pump, so for a few dollars more for a switch with a lever is well worth it,

Incredibly helpful, thank you!

Good stuff. thanks for your time. It's appreciated.

That was just great! Appreciate it much- Kudos!

Very well explained. Good belch too!

check to make sure that pressure tube isn't clogged including the tube and the opening on the tank side as it can get clogged up with sediments rust etc.... use a metal coat hanger and make sure the opening on the tank side is clear ... the coat hanger should go inside the pump a few inches... that was my issue

"Because that's how people talk"

U know this mans knows what he is talking about has a coors light next to him

Thanks for this video.. I learned a lot.. 🇵🇭🇵🇭🇵🇭

Good video

Thanks, that was really great!

Loved it, way to keep it light, fun and informative with common problems! Just the info i was needing. 1 question: any lubrication or spray to help extend and minimize oxidation?

Good info on high pressure adjust

You sure saved my ass!

Thanks alot

Lenny; I had to turn my pump off and drain the water so i could change a 5 micron filter, and now the pressure in my tank is at 0. My pressure switch does NOT have a lever, and the pressure is not rising when i turn the power back on. How do I re-start my pump?!? Can anyone help? Everything I find online only describes the method that requires you have a lever!! Any help is greatly appreciated

Thank you!!

If I have two jockey pumps and two main pumps,do I need two pressure switches?

I just changed a pressure switch 30/50. I adjusted to 40/60. I turned turn off 2 turns now it closes but pump don't kick on. Why?

can i.weld.this? i.dont have couplers.and fittings

Thank you!! Very informative video!! I just replaced my tank as well as this device, but am having a problem that is mind boggling. My settings are 40/60. When the pressure drops just past 50, it dives to 40 immediately, contacts clicking twice, then fills the tank. This was the reason I replaced the tank thinking it was the tank, but same problem. Any idea? Thanks, again for the great video!

Will this switch protect the pump if it’s running dry?

Wow, I didn't know those ran 120V Lenny. My zone valves are all DC voltage and they look the same. That's a learning moment for ME.

Good video! I just replaced mine with a new one. But I have a question..... while the water is running, does the switch normally click on and off during the time the the water is being used!?!

i'm not sure if this channel is still active but my question is, can that rubber (diaphragm) be replaced?

Thanks for you information I have same control device for Pump When I turn on the pump switch it didn't contact each other, so I contacted them physically and it worked and maintained the power after 1 minute pume was off Do you think My pump is broken??

hi, my switch contact point don't open and my pump runs for a couple of seconds then stops. I cleaned all contact points but still the same. Help pls.

I want to create a shower loop which recycles 2 gallons of water when taking a shower. It basically fills up a container with fresh water then pumps that water through a water filter and out the showerhead; recycling the water in the container for the duration of your shower. Can I use one of these to measure 2 gallons of water to fill the container?

Is there one that looks at the pressure interning the pump and would opens when pressure drops? I am trying to protect the pump

I would like to have one of these to add to my booster pump that I have hooked up to a water tank with a trigger to release water. My question is, once I let off the trigger, will it turn pump off and once I pull trigger, will it start pump again. Thanks

what will happen if we remove the small spring?

Should the contact points be sparking? The entire pump/motor/switch assembly is brand new and installed by a pro. Thanks

sand paper 250 grit, you're welcome...

I Don't know what happened but I'm not seeing your messages no more for some reason.

Can I purchase a diaphragm for the switch anywhere?

That Stuff will Rot your Brain....

Hey Lenny.....substitute "That's how people talk" with "That's what she said when the bed broke" .....sounds a lot more professional.

Can i use that on air compressor sir?

for how long does the pressure switch last?

My 40 60 works awesome

😂 That Coors has a lot of unnecessary drawn out explaining that would drive an ADHD person to find the next KZfaqr! Luckily, I'm not one of those cases so good job. LOL

Will it work at a 12v pump?
