float switch wiring diagram for water pump

0000065062 00000 n trailer 0000067502 00000 n When my well pump comes on my line voltage goes down. If the pump won't turn off the cause may be a damaged pump control, a plumbing or fixture leak, or a well problem. ?[42}rLUs>GsRG You can also check resistance between each lead and ground - and to the well casing as sometimes that will show up a short not between wires but between one wire and ground. Tradeshows Meanwhile, I have marked the identity of the wires in your wiring diagram. It's difficult to make an exhaustive check of the wires for leaks or weak shorts to ground without pulling the wiring out of the well since at the wire ends there will be a connection through the pump motor - giving some resistance but not a quantity that we know without help from the pump manufacturer. On 2021-09-23 by inspectapedia.com.moderator (mod). Knowing the context is diagnostic: is this a new indication on equipment previously installed and working properly or has the indicator always been on since installation? I could use a different circuit to test using a combined 40 or combined 60 amp breaker instead.

As with the seal-in relay above, the wiring necessary for the alarm contact will vary based on your control equipment. Thinking carefully about when you want something off, and when it should turn on, will help you as you visualize the wiring and apply the schematic to real world control. Usually it's monitoring current draw or Amps as an indicator that a pump may be running dry (and thus subject to damage). We could regain functionality by manually resetting the switch. When tank is full and float switch breaks power, everything is normal / quiet, except for pump control relay clicking (I assume on and off, but no momentary show of amps comes up. Privacy & Cookie Policy Page top illustration courtesy of Carson Dunlop Associates. The next line up is for a high-high-level alarm (i.e., a higher level than the high-level hysteresis switch). ok the deep well pump i installed 2 years ago quit,,, its a 220 v 3 hp about 100 foot deep,,,. top photo credit: PEO ACWA via flickr cc cropped.

Typically you would use a clamp-on ammeter on the individual leads to the pump.

It took forever [for the water tank pressure] to get past 25 psi, but once it hit 30 psi it took about 2 minutes for it to reach the cut off pressure of 68 psi (my pump and tank are quite a ways from my house and I adjusted the pressure). Appreciate any insight you guys might have. In the Index to Related Articles you will find an article titled "Pump will not start". We've given you the wire sizes that would be required for that run length. On the bottom line you have the wiring terminals for the switches providing hysteresis (wires 1 & 2). It also says the current motor running loaded amps is 5.9 (not sure that's useful) Can I just insulate? What are the brand and model of the old pump? endstream endobj 297 0 obj <>/Filter/FlateDecode/Index[57 186]/Length 29/Size 243/Type/XRef/W[1 1 1]>>stream startxref May I ask are you the same person who I started all this with, or do the moderators change? Help. And now your simple solution has burned up a pump motor. I'm showing 240 on the 2 wires of the relay coming from the power box. As the liquid fills past the first switch, it opens. @Guy Priano, If you are not trained and familiar with proper, safe electrical wiring practices don't try it; On 2018-12-26 by (mod) - how to test a submersible well pump wiring and motor - typical resistance values. Any help would be greatly appreciated thank you in advance. If the pump runs too often the cause may be a control problem, water tank problem, piping problem, or a well problem. I only have three (3) wires at the well head and that continues through out the remainder of my system being the breaker shut off and the pressure switch. Is the motor on the submersible pump bad. 2:t-`yP yqC M+e2MYt($@@0C@23AQaF|,jX*&]IB)9,&Tq3!EOwK 0000021863 00000 n These4-wire well pump wiring connections are typical for a single-phase submersible pump. Thats right. Perhaps having the capacitor blown also can break the blue circuit assembly thing for the capacitor in the circuit box and I need to replace that? StuartI can but make a feeble guess as you don't give the name of equipment, model no. Alright, let me lay it out: Continue readingat WATER PUMP WIRING DAMAGE or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX.

I bought some new property that has a deep well pump which is 375' to 400', it is a old homestead when the previous owners left they cut all the wires in well casing and at concrete slab,why is beyond me. this pump being a 2 wire only has the pressure switch no control box my email is bodyman36@hotmail.com. Where do the black and white wire go on a well pump that has a regulator switch, Anon:Please see your question and my detail reply athttps://inspectapedia.com/water/Well-Pump-Wiring-Damage.php, Why would the wires in my well keep breaking, On 2019-01-17 by Ronnie Neathery COPYRIGHT 2020 Automation Products Group, Inc. close (i.e., turn on) a Normally Open circuit, or it can open (turn off) a Normally Closed circuit, Mount or suspend your switch at the desired level, This cyclical action is called hysteresis. I have suspected the protection device and glad your thinking is along mine.

water tank pump meter is not working Gil How do I fix this please? Swapped out motor control and float switch with same known good components - no change in problem. 0000083397 00000 n 2. check every wiring connection for looseness, overheating, arcing, corrosion, etc. . The low-level switch wires to terminals 1 and 2, the high-level switch to terminals 3 and 4, and the contacts for seal-in relay A to terminals 5 and 6. 0000011933 00000 n Greg, I'll be glad to research this further as from your question and image I'm not confident I can give a correct answer right-off. We can add a second switch to create hysteresis. It took about 5 minutes to fill the 120 gallon tank. Terms & Conditions So not knowing it's particulars, amp reading may or may not help unless it is so far off chart for any average 1/2 hp pump. Watch out: if you are not trained in safe electrical work you could be shocked or killed. Could the problem be a leaky foot valve if the pump doesnt lose prime? For larger motors, inrush current (up to six or eight times full load current) becomes an important factor in the starting and maintenance of the motor, rendering contactors insufficient as stand-alone motor starters. When I touch well casing I feel electric current but pump will not run, On 2021-09-28 TonyaMost-likely yes there is a central underlying issue - either a very low flow rate well or simply a loss of well prime. Edwin Water stopped working. Have you tried disconnecting from power (first turn power off) and then checking the resistance between the leads to the pump? Don't fool with it. 2. Thank you. At that point, both the low-level and high-level switches will be closed, completing the circuit, and activating motor relay P to start the pump. After doing so, he turned the breaker back on and something popped in the fuse box leaving a scorch mark inside of the fuse box and at that point he determined that the pump wasn't running.. so, essentially we paid them $800 for a repair that didn't fix the problem and now are saying that our pump is bad, that they will need to pull and replace it and that will cost me an additional $1000. my questions are numerous.is hardwiring and bypassing fuses standard practice? Vendor Compliance Manual, Automation Products Group, Inc. @Eddie, When I check the power coming to control box L1 the white wire reads 0 and the black wire reads 120. But prolonged rapid on-off cycling might indeed burn up a pressure control switch.

I think the root problem is that you've run a considerably undersized wire, and therefore have so much resistance that the voltage delivered at the far end is completely inadequate and the wiring is at risk of overheating and being unsafe. Keep in mind that motor tests are tricky because once parts start spinning an internal winding can move, changing the electrical properties of the device. With that being said, my power wire from the breaker box to the well is buried underground.

Watch out: don't try electricalwiring yourself if you're not trained as you could be shocked or killed. Yes I agree clamp-on would be best and until this point have not had need for that specialty meter, but should get one. 0000066945 00000 n Do keep me posted. Software Downloads Similarly, once the high-level switch opens, the pump will not run until both switches have closed. @Joe, On 2021-09-25

Illustration: Franklin Electric provides this Pumptec Control Box # 5800020610 that includes a pump protection circuit that prevents the pump from running dry: particularly suitable for low-yield wells. 0000066056 00000 n You could have a damaged wire enroute to the pump or a pump motor winding that's shorting. When current started passing through the wire, there was enough missing insulation to trip the breaker - like a ground fault on a 480V system. The sticker on the motor says 'Model 2801054915' HP 1/2, volts 230, The chart in the box for 1/2 hp 230 volts says "Main BLK-YEL - 4.2-5.2 Ohms" My ohm meter says 1.3 ohms for this. hbb2d`b``3 c ; 0000065780 00000 n 0000065229 00000 n the last one (1) connects the capacitor motor. More details are, at WATER PUMP CONTROLS & SWITCHES - home. 243 56

However, seal-in relay A has been activated and closed, bypassing the now-open switch L (effectively sealing it in), so the pump continues to run until the high-level switch H opens. 0000001890 00000 n A few minutes later it repeats. IF then you find that the pump delivers water normally, the problem is probably poor or low flow rate. I see. @Dan, well flow rate is inadequate + a pump protection switch turns off the pump to protect it from damage should the pump be run "dry", pump pressure control switch pressure sensor port OR the small pipe nipple or tube bringing water pressure to the pump switch is debris clogged, Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the. Lets say a valve downstream of the tank is opened, allowing liquid to drain out of the tank. Do not just insulate and turn power back on.Leave the circuit off to avoid a fire and shock hazard - sorry I know that's not exactly convenient. On 2020-01-19 by (mod) - low-voltage problem. I cut the insulation back and found that the leg I was loosing when the pump came on was damaged. If the air temperature is over 100 degF, the pump may be too hot and its thermal overload switch tripping because of the environment, not a pump problem. He used a piece of wire to jump the blown fuse and we still had spark at the switch, but in his words, not enough voltage to actually turn the pump on because the wire was too small. and let me know what you think. @inspectapedia.com.moderator, Sorry for slow response; I'm working many projects on large acreage. Not exactly what's on the chart inside the box, but not far off. @Eddie, hbbd```b`` qdc d="Y`76;"fFH`? sales@apgsensors.com, Float Switch Installation Wiring And Control Diagrams. ci I reinstalled the device and played with both it's "restart delay/calibration adjustment adjuster" and played with "sensitivity adjuster". septic I'm not sure if the system is water logged or not. WATER PUMP WIRING REPAIR at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. Use a VOM in ohms setting to check resistance across the capacitor. We continued using water while power was out but had no water pressure when power came back.I replaced the old pressure switch with a new one that has the little lever to manually switch on the pump to refill the tank when pressure drops too low. Over used/overworked system? Please tell me the "unit" brand and model, On 2020-12-19 I appreciate your insight on this. This article describes troubleshooting a submersible well pump that was causing tripped circuit breakers and that pumped water only at a slow, reduced rate and pressure. ReallyThe pump may be a 220V motor unit - do you know?

You need to know the normal resistance for your specific well pump brand and model. nG,-tMYe?2S_Dw| u{tKN[EkZz9FKA;H }1% ZJ\EZA gd19NFHOyO8WI/(I*t1G. Some of the well pump troubleshooting suggestions in this list can be found at the Betta-Flo Jet Pump Installation Manual from the National Pump Co. SE CABLE & WIRE SIZES FOR LONG RUNS they are coming tomorrow to change it but seem unsure of the issure, On 2021-12-13 The symptoms that I am seeing is that it it taking my well about 7 to 10 minutes to fill up ( I have a 120 gallon galvanized tank with no bladder). hb```c``c`e`gd@ A([Ua&S0pttt $b~bf:.c V%sf8H%99>A10v)"@;i(` ! There is power when not running??? When I first looked at it, one of the two 120 volt circuits had its breaker tripped, the other didn't. If the meter does not move (no current flows) the capacitor is "open". Replace fuse or breaker - does the pump run and keep running normally? Careers, ISO 9001:2015 Certification Lightning strike Before allowing for wire length, for EXAMPLE, a #10 copper pump wire will have about 0.214 Ohms of resistance for each 100 feet of a pair of leads to the pump. See WATER PUMP SHORT CYCLING CAUSES if the pump is turning on and off too frequently. It sounds like an electrician is needed to trace the circuit to find the break or open connection. *dEGdURI38PrS% -ZP~}@Fp($OJ(^}3u3:^(Bzc6wn)1%4brU=Zu5Hk'126$F~+ Cdd6DO JikIM mSySTqzDj#foMDZhUS-4%t?xWP52h\OCa>MX&Ew{=!9dJZ$#zXFu}39_{w^6'xl$[R +L9iQH `kcN[9;bn9,,=S?}[5SL2$}F9&H^[4BF!y&ZA3Q=2C7zg{0CLW5yKa"z.sIn:0]#61a\.&| 5d?ro e20%X_iKhrx /[[=JK/7PI^B! A test of the pump motor windings for evidence of wear or shorts (abnormally low resistance) Tests of the pump wiring are made by individually connecting between each wire (at the well head) and ground. The problem could be a bad switch (have it replaced) or the pump itself could be bad. I have a submersible well pump that fills a 5000 gal. Watch out: if you're not familiar with safe electrical wiring and practices, don't fool with these tests yourself as you could be shocked or killed.Your electrician can do some simple tests, measuring resistance, to get a clue about what's happening.If the pump is a submersible unit, in the well, it may have to be pulled in any case, as the problem is either the wiring or the pump or its control switch. Sorry to say you may need to pull the pump to check wiring and pump motor I'm a little bit lost on how to proceed, I have a couple ideas: I hooked up new pump and forgot to change the switch from 220 to 110, will this hurt the pump capacity? 0000021187 00000 n Common causes of intermittent pump stopping when power remains are. This discussion has moved to WATER PUMP WIRING DAMAGE, On 2022-01-26 is there any way I can test pump. 0000010381 00000 n So the tech went about replacing the tank and all components. What's not working, Amit: ; endstream endobj 18 0 obj <> endobj 19 0 obj <> endobj 20 0 obj <>stream You have not told me if there is one start/run capacitor or separate individual run and start capacitors. bilge @Cliff, My understanding is we're at 'the motor needs to be replaced'? that has some nice wiring illustrations. %SWGCD.`gD)!ChxV ]f=bc.I9GYQt*G!3K*u/45H>`T!J~WY$sD"KA~,8`pU1%[&fiZ5J}p{FuDC3dz71AXmV With a KARI series 2L float switch, you get the same hysteresis control using one switch and two wires instead of two switched and four or six wires. I ohm ed out the motor and it is open (infinite resistance) to ground both legs and 3.2 ohms between the 2 leads going to the motor. Your repair tech or electrician will do some tests to find out if the problem is a seized pump motor or shorted wires - that's when we will know what repair is needed. It's just too dangerous. Well look at single and double switch arrangements and how to wire them, and then look at equivalent circuits using Kari series float switches. EricThe burned wiring tells us that there was (probably) a short circuit in the wiring and/or a seized pump motor.Watch out: It is of course unsafe.I worry as well that no fuse blew nor circuit breaker tripped.
