How to Wire a Pressure Switch
In this video, we show you the best way to a pressure switch for 115V and 230V pumps. This method will work for any pump that runs directly off of a pressure switch - including jet pumps, well pumps, lake pumps, cistern pumps, booster pumps, and more!
If you're replacing a pressure switch, all water pressure must be relieved from the system before you remove the old switch. With the power OFF, open the nearest tap (usually a hose bib on the tank tee) until the pressure gauge reads 0 PSI, then close it. Leave the power off until you're ready to test the new switch/check for leaks.
Be safe when working on/around electrical devices. Always turn off the power to the pressure switch before you work on it. If you're not 100% confident in your safety do not do the work yourself, instead call an electrician.

Excellent video. You may have covered in another video- but learn from my mistake- a Schneider Square D pressure switch is great. But I first bought one with the LEVER on the side for my well irrigation system. Bad move! Get the one WITHOUT the side lever. Works completely differently. After I got correct one- works great.
I know this is like 2 years after the video was posted, but thank you. You are friggin awesome.
Thank you. I was having trouble figuring out how to wire a pressure switch to my deep well water pump. Your video and expertise pointed me in the right direction. 👍🙏😎 July 17, 2024

good video ... Given how inexpensive the switches are I'll get one to have on hand I think. The 230 VAC wires are 2 120 VAC legs out of the panel or generator that are 120 degrees out of phase from each other with a neutral wire (ground in your video) For testing meter set to volts neutral plus either leg will read 120 VAC, across both legs will read 240. I say this because a trailer snatched out the wires on mine (my fault entirely .. ) After many high volume low quality words, I needed to put a meter across the wires and label so I didn't break something 170' below ground and then complicate the simple repair. I will take your connectors tip as the guys that did mine screwed down bare copper, and not even twisted.. :( Saved all of $.03 cents no doubt.. (more low quality words). Everything that happens teaches something.. Thanks for the video and confirmation of what I had planned.
Finally found video that shows whether or not i can use 220 on switch from 110.

I was following the diagram on my switch purchased locally (Mexico) and it stated L1 M-M L2 so I wrongly believed it was Line(Phase) 1 - Mass(neutral) - Mass(neutral) - Line(phase) 2, and now after checking your video I see what I did wrong, but still believe that the diagram should be clearer, it should read something like: Neutral In - Neutral Out- Line Out - Line In, that way people would without a doubt know the Breaker neutral goes to the first terminal, the pump neutral goes to the second terminal, the third terminal goes to the pump Line and the Breaker line goes to the fourth terminal, after rewiring like in this video my put together hydropneumatic is working like intended, thanks.

I have a submersible pump and a Square D 9013FSG2M4 30-50 230v pressure switch with low pressure lever on the side. 10 years ago a plumber moved the pressure tank to make space for a basement bathroom. I'm not sure if my switch is wired right since then . Wires from my breaker sits on 1st and 3rd screw. Wires to well pump on 2nd and 4th. Is this okay?
@abm2958

Yes, power in and out of each set of contacts for 220v.
Is there anything that can be put on the contacts to protect them? When the contactor lifts off the contacts there is a little spark. Over time that'll leave some build up on the contacts and they'll need to be cleaned or replaced. Just wondering if there is something that can be done to increase the amount of time between cleanings. Turning off the power, spraying some contact cleaner and some canned air to accelerate evaporation isn't too big of deal, but I like the idea of protecting the contacts better if possible? Also, it looks like SquareD makes a contactor replacement kit. It isn't much cheaper than a whole new pressure switch though. Edit: Thanks for the video by the way. It helped me troubleshoot my pressure switch. I was getting 70 volts on the middle two terminals and 245 volts on the outer pair. Helped me figure out that the contacts were dirty. A quick short spray of brake cleaner with the power already off and a can of air to ensure the whole area dried out quickly, and my pump was back in business.

Where to wire a wall light that comes on with the well pump ,220 volts , 110 volts to function light .Goes off when tank gets pressure ,
Hello RC Worst. I'm a big fan of your videos, they've helped me so much. Need some advice- so i am setting up a 2nd pressure tank downstream from my home's primary/standard pressure tank. A well pump supplies water to the primary pressure tank which supplies water to the house faucets, and tees off after the faucet line to feed into secondary pressure tank which supplies water to faraway irrigation hydrants. My plan is to have the 2nd tank's pressure switch control a solenoid valve (normally closed) that will sit between the outlet of the 1st pressure tank and the inlet of the 2and pressure tank. The 1st tank pressure switch controls submerged well pump, and 2nd tank pressure switch controls just the solenoid valve to let water into the 2nd tank as needed. The idea behind this is to be able to stil have pressure in my 300+ ft long irrigation line and irrigate at any output I want at any time without the consequence of robbing pressure/water from my household faucets and causing my well pump to rapid cycle (if I was feeding both the house and the irrigation off just 1 tank, it would have to rapid cycle lot just to keep up with the demand). SO MY REAL QUESTION IS- can I just hookup the 2nd tank's inlet solenoid valve to the same wire terminals on the pressure switch that a well pumps wires would go? So instead of powering a well pump, it powers the solenoid valve to open and let water into the tank when tank reaches low pressure cutoff.
Opinion of a low pressure cutoff switch and overide lever ?
what size fork terminals did you use? great video!
@Vincent_Sullivan
Жыл бұрын
Buzz; There are 2 things that are important for crimp on terminals. The first is the size of the wire they are supposed to work with. In most cases (I am sure there are oddball exceptions) if the insulation is yellow in colour the terminal is intended for use with 10 or 12 gauge wire. Blue insulation is for 14 or 16 gauge wire, and red insulation is for 18, 20, or 22 gauge wire. Mr. Worst was using terminals with blue insulation so he was using wire size 14 or 16 gauge. The second thing is the size of the screw terminal the fork is designed to work with which is basically the size of the gap between the forks. Most electrical equipment screw terminals designed for use with 14 gauge wire will be using a #8 or #10 size machine screw. You would have to look at the screws on the equipment you are planning on using to determine which size terminal to use. I hope this helps...

Incoming power wires are either L1/N for 115V or L1/L2 for 230V.
Looks easy enough but why are my jobs always more difficult? I have a submersible pump with 6 gauge wire on the line and load side. Neither of those wires are pliable enough to wire to the pressure switch and the wires are too big to fit on a wire connector small enough to fit the switch terminals. You are usiing what looks like 10 0r 8 gauge stranded wire which is much easier.
I installed a new jet pump that has its own pressure switch. That being the case, do I still have to hook up my already existing pressure switch?

Hi. I'm using a brand-new A/C compressor to push air (instead of refrigerant), as part of an on-board air system for my Jeep Wrangler.

My second question is for the switch that I've rigged to turn on/off the compressor, where does the power wire hook up onto the Square D?

The tank was only filling about 1/4th its size. I lowered the air pressure in the tank to 10 psi but it still only fills to about half now. I adjusted the switch to raise cut on to 30 and cut off to 75. The thing will cut on at 30 psi and within 3 seconds, reach 75 psi and cut off... I can't figure this out. It must be dirt in the switch right? Why else would it reach max pressure in only a few seconds? the tank has plenty of air in it. Now, it has been in service for decades and I have had to clean the contacts 3 times, so replace the switch right?

@@paulvelte the tank's job is to protect the expensive pump from short cycling. I would recommend that you don't deviate from the proper setup of that pressure tank. If you want a storage tank, then add a storage tank. Sanitization becomes an added complexity though. Water systems put large tanks up high to let gravity produce pressure in the system. There is likely a small scale version of that but watch out for extra maintenance or managing the sanitization of the water.

@RCworstwater
4 жыл бұрын
The only reason you'd need to move your pressure switch from the pump to the tank tee is if the tank is more than a couple feet away from the pump. If the tank is too far away the switch is prone to rapid cycling due to the "wave" action that the pressure tank usually absorbs.
