float switch wiring diagram for water pump

A water logged pressure tank will quickly if not immediately reach cut-out pressure and turn off the pump (unless the pressure control switch is itself faulty and not sensing that the tank is up to pressure). Suspecting a short, I tested the winding resistances on the motor, and get non zero values across. Thanks, To answer with confidence I would need to know more about how and where you made your tests and also whether or not you have one simple pressure control switch or a switch that is in turn operating a 240 volt relay control showing at the top of this page. 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. That particular situation happens NOT very frequently and intermittently (without any pattern). At the regulator, I see 120 volts to ground on all the leads with both breakers connected. 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. 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. It contains some good diagnostic steps to help you out. Watch out: your pump wiring requirements may differ: consult the IO manual for your pump and pump controller. Stephen Large switching capacity: 5 A at 220 VAC , Water Supply Control with Pump Idling Prevention and Abnormal Water Shortage Alarm Plug-in Type 61F-G1P Dimensions: Page 7 Automatic Water Supply Control with Pump Idling Prevention , interruption, press the pushbutton to momentarily close the circuit to start the pump . Weve got level control, reasonable pump-motor life, everything we could want, right? When the high-level switch opens, the motor relay P opens, stopping the motor, and seal-in relay A opens. 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. When I replace the wire it will be in conduit. Just need to know what kind and size of wire that will perform without problems. 0000002266 00000 n <<2EA28EE467A96042AB7B742BC2F06FCC>]/Prev 546471/XRefStm 1890>> Dan, On 2021-11-27 @Eddie, The burned wiring tells us that there was (probably) a short circuit in the wiring and/or a seized pump motor. As a point of comparison, a dead short will show zero or close to zero resistance. iYF AaronI cannot bet your life or the fire-safety of your building by making a guess at exactly what wiring you're trying to connect - I've got just no information about what your pump and control wires are.Typically in electrical wiring Black = hot and White = neutral, particularly on 120VAC circuits.However if your pump is a 240V pump someone could have run a two wire circuit to it and both wires could be hot.So sorry but I can't give an answer to what wires go where on an unknown switch for an unknown pump. My water pump keeps shutting off. @Don, Watch out: if you do not know how to perform electrical wiring and circuit tests safely you could be shocked or killed or could start a building fire. I appreciate your insight on this. A 2-wire 240V well pump may have the following wires present and connected as given at the control box: A 3-wire pump control box may actually have 6 physical wires present as follows: Above: Example wiring details using the Franklin Electric Pumptec-Plus pump controller - citation and manual links provided below. ? Lets say a valve downstream of the tank is opened, allowing liquid to drain out of the tank. 0000021493 00000 n hb```c``c`e`gd@ A([Ua&S0pttt $b~bf:.c V%sf8H%99>A10v)"@;i(` ! The Type FYG is designed to meet higher horsepower and pressure requirements. So what can we do to protect the pump motor? I am assuming your 5000g tank is not pressurized and that no pressure control switch and loss of air in the tank is causing trouble. Water tank Our Comment Box is provided by Countable Web Productions countable.ca, Click to Show or Hide Citations & References, anytime I put on my water pump, the cucuit breaker Trips, 4" ENVIRONMENTAL E-SERIES PUMPS OWNERS MANUAL, PUMPTEC CONTROL BOX & PUMP PROTECTION DEVICE IO MANUAL, PUMPTEC-PLUS PUMP CONTROL & PROTECTION SYSTEM INSTALLATION GUIDE, PUMPTEC QD CONTROL BOX INSTALLATION MANUAL. 0000003564 00000 n 0000002070 00000 n @Guy Priano, So no more liquid is coming into the tank from this pump. That's why the amps test is useful, to get an idea of the condition of the motor before pulling a pump. We need to wire both float switches back to our control circuitry, plus we have to add the contacts and seal-in relay A. Checked continuity on wires from well head to motor. Weve spent quite a bit of time talking about how float switches can be used to turn pumps on and off, so its worth taking a moment to talk specifically about motor starting and motor control. The Type FRG is reverse acting: the contacts open on falling pressure. On 2021-12-12 by Inspectapedia Com Moderator. Pump is about 5 years old without problems prior to this.What could be causing this issue?? Is there some procedure I've missed for replacing the capacitor that does this? @Sam Smith, I could use a different circuit to test using a combined 40 or combined 60 amp breaker instead. our sumersable pump starts but a few minutes it trips. WATER PUMP WIRING REPAIR at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. So there we have it. `4T5FJmH)s 0000003260 00000 n (far right wire see image) - Valerie. This sounds to me as if the motor is overheating or is damaged and is drawing high current (amps). Daniel. 0000027322 00000 n In general you would not expect to see voltage on the wires to the pump unless the pressure control switch was in the closed position. I'm speaking beyond my competence but from what I've been studying just recently, there are useful relationships between motor current draw and other conditions besides a failing motor. 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. No constriction ( unless caused by low voltage or voltage drop somewhere slowing the pump momentarily and intermittently) that I can not find when looked for. I'm not sure if the system is water logged or not. I reinstalled the device and played with both it's "restart delay/calibration adjustment adjuster" and played with "sensitivity adjuster". In the Index to Related Articles you will find an article titled "Pump will not start".

Here is what I found: I was showing 238V at the cut off box at the control box. maybe it needs a little more current, but is not actually shorted? @inspectapedia.com.moderator, Yes current variation happens in conjunction with growling as I indicated in my previous statement. When I powered the system up nothing happened so I started trouble shooting the system as I always have. Wire on well pump charred. If the well casing is metal then connect the ground lead of the VOM/DMM (be sure it's a good clean connection) to the well casing or metal piping). @Cliff, ok the deep well pump i installed 2 years ago quit,,, its a 220 v 3 hp about 100 foot deep,,,. Careers, ISO 9001:2015 Certification I was thinking that the caps may be bad and it was pulling too much current at start up and tripping the breakers. 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. by inspectapedia.com.moderator (mod). Work with power off and disconnected from the pump circuit. I need to know how to wire my pumptec to my control box and my float switch.the way I have it wired now there is still one twenty going to the pump in all three wires even though the pumptec turned off the pump there is no water coming out of the well. 0000066225 00000 n changing the caps did not help. Take a look at ELECTRIC MOTOR DIAGNOSTIC GUIDE Hi, i need help, anytime I put on my water pump, the cucuit breaker Trips, what could be the problem? 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. Common causes of intermittent pump stopping when power remains are. 0000002324 00000 n If I open up the box containing the wiring for the pump and the starting capacitor, I could get both breakers pushed in. I'm showing 240 on the 2 wires of the relay coming from the power box. by Inspectapedia Com Moderator, @Rob, I know this idea is probably stupid. Damaged wire Do keep me posted; what you find will help others. I noticed a wire was charred and when I started the pump again saw a spark. Probably not, Jose. Appreciate any insight you guys might have. If the well is toast, I think the shortest path to getting water to this house is connect to municipal water rather than repair the well, but if there's something I can do with just the electrical end of this to get it going, that'd be ideal. Usually it's monitoring current draw or Amps as an indicator that a pump may be running dry (and thus subject to damage). Is there a main issue that could be causing these other issues to fail? I may have been hasty (trying to answer too many questions too fast - apologies). I just wanted to be sure problem is not above ground. The third time it happened, we were unable to manually reset the switch. Its the burnt wire on the right), Wire fried on well pump. @Joe, I am an industrial electrician and I'm very familiar with 480V-2300V systems. Tradeshows We had a storm a few days ago and lighting (sounded fairly close) that cut our power off until the utility company fixed things a few hours later. So we could have low voltage, or a failing sensor in the pump protection device itself, or even a constriction in the piping system (you've checked for this). He immediately noticed we had a blown fuse in our service box. 0000004241 00000 n The microswitches inside the float activate at factory-set angles as the float tilts, and the preprogrammed control circuitry responds accordingly. endstream endobj 253 0 obj <>stream Thank you . Not exactly what's on the chart inside the box, but not far off. As the liquid level falls, high-level switch H closes. @Anonymous, However, with a little bit of fundamentals, youll be wiring like an old pro in no time. my meter says 13.3 for this, so both are low, that first one could be a lot too low. @Eddie, Note , I have above ground septic bed with lift pump. septic However, if we add a second switch that is identical to the first, and wire a seal-in relay around one of them, well get the control were looking for. This is a big world water pump 220 volts 2 wire, With the closed circuit on the pressure switch the voltage reads 250 volts on one leg and 0 voltage on the other leg, I checked the voltage on the line and load on the pressure switch one side is 250 and the other side is 0. this doesn't change anything. 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. 0000067069 00000 n 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. jrTT-[!3)AV_ew~-$c640`a88m43!},8BiF ` 7(Z Zp(3 fLhmk.X[H#%;"NUP= cBvqHs0j>2*y|9<>W1f$mLbIfZ'C>5"K`j3Wy!/0_,. the pump switch will not cycle on. Start by identifying the exact pump protection advice installed: brand and model, then tell us that information; let's both read how that device works and what might cause it to short cycle. 0 xref A new motor without the cable will have about 20 MegOhms resistance and a used motor that's still serviceable may drop to 10 Megohms. No seal-in relays, no extra switches, nothing else. Not two additional wires, just two wires. User Manuals I have a 220 volt submersible pump for domestic water. check supply voltage right at the electrical panel. A diagnostic step is to stop using water for as long as you can - several hours or more - to let the well recover (if it can). How do I wire a old well pump . I have a submersible well pump that fills a 5000 gal. JoseThe no. The new series FS-400 vertical float switches and series FS-410 mini vertical float switches feature all stainless steel wetted materials, usher-reversible logic function, and high operating temperatures. There is no low water level. Once the liquid level falls below the low-level switch, the pump will run until both switches are open. Is it worth trying giving it a higher amp circuit? I know I need to go towards the pump to see if there is another junction box and if so if it's showing 240 there. If the pump motor is seized (or overheated and failed) that in turn can be caused by a variety of problems such as well running dry or pump running constantly. How to install & wire a pump control box. 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. Goulds Pumps, an ITT company, offers an excellent submersible well pump diagnostic and service manual. Please find your question repeated along with a detailed reply and our suggestions for wire sizes and an alternative, now found at So this other well pump with problem is unknown make, model, depth, and I can only assume 1/2 hp as indicated by control box (who knows if that is even correct one for pump). startxref My water pump cycles a lot. 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). No affect at all , except if I left it in reset position, then clicking intervals slowed way down. Your electrician or pump installer will perhaps test the pump circuit and may find shorted wires. Also for other readers we provide: hb```06# Check with VOM at the pressure control switch or at the pump wiring, Check that the pump pressure control switch is trying to turn on the pump and that there is voltage at the pump wiring, Check the switch contacts for burning or wear, Check the tubing connecting the pressure switch to the pump housing for clogging, Turn off electric power to pump, see if you can move the impeller or motor - if it won't turn it is jammed or damaged, Pump motor shorted out, jammed, burned up, Fuse blows or breaker trips as soon as the pump tries to turn on. You could have a damaged wire enroute to the pump or a pump motor winding that's shorting. It stopped working. As the liquid fills past the first switch, it opens. During last stay at property during heavy usage the water would recover slowly. Since I will already need to connect the two (2) hot leads together. 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. that has some nice wiring illustrations. Water shut off and when restarted saw a spark. 243 56 It is only a gravity supply to a Goulds booster pump on a separate circuit controlled by Square D pressure switch to supply pressure to bladder tank. That sounds like you might have a low resistance and developing short in the motor run winding or main winding. My water stoped after a bad rain storm I changed the pressure switch and got new control box.
