Short cycle alarm
Got water again. SHMBO is happy. I guess I'll never teach her to crap
in a bucketVBG I feel kind of dumb. The control box has motor overloads. Only had the pump since '82 and didn't know that. At least it was a cheap fix. OK, the problem was short cycling. Air bladders out of air and pump running 15 seconds to make pressure. I'd like to build a better mouse trap. I'm thinking of a short cycle alarm. Get a timer relay that trips when power is applied. If power drops before timer runs out, apply power to buzzer. Should be just a few relays and wiring. But my brain is pea size when it comes to EE logic. Can somebody draw this up? Or, I'm open to another idea. Karl |

The water well system on this place is about the same age as yours. The first owner replace the pump once due to pipe freezing at top of well. We replace pump two years ago due to sand blocking. The pressure tank has never been replaced. My neighbor has replaced his tank twice in the same time frame but used cheap tanks. I can look up the name/part number if you are interested. Paul |

Two 120 gallon tanks at $800 each. Plus, I can see the plumbing would never come apart. I'm guessing a couple hundred here for new fittings and pipe. This is a five horse well and two inch plumbing. Anyway, keeping them topped with air will have to do for a while. I've been doing this 1/year with no trouble. I might have forgot last year. Karl |

Came from the local wholesale supplier where he still had an "in". The farm I worked on many years ago... just hooked up a light to the pressure switch. When the light was on the pump was running (Doh!) and it was pretty easy to deduce that something wasn't right when the light was going on-off in a funny pattern. A simple delay switch might do the trick too. -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

Karl You got me curious, so I got the brochure from the well file. It is a WELL-X-TROL by Amtrol, Inc. Probably their WX-251 unit. They are permanently pressurized at the factory. Ours has been emptied many times for various reasons and have never had a problem. Paul |

The one time I worked on a well pump, it had some kind of
gadget that "regulates the air". I think I finally figured it out. Diaphram, and a couple check valves. Every time the pump went on and off, it injected a bit of air into the well tank. Made perfect sense, to me. Bit metal air compressor, and blow the water out of the tanks. That works too. Twice a year, with clock changes and smoke detector batteries. -- Christopher A.

Better replace the start capacitor and relay. It will not be long
short cycling and age are sure signs to me. Grainger or an equivalent will have the parts. Make sure the run caps are good too. You should have 10.5 amps on the RED or start leg. If it is less add the appropriate capacitance. Scott |

I think I'd use a 555 timer configured for whatever you think a minimum run time should be, use the circuit from the app note that starts the timer on rising voltage. power the timer from a wall wart running on the primary power, trigger it (start it) with pump start. Use a standard latch circuit to set an alarm if the power to the motor is off when the timer expires. |

They can be set up in many modes. They would handle the pump relay (not the pump direct). I use one of these in a similar manner to protect my air compresser so it doesn't run too long or too often. http://ab.rockwellautomation.com/Relays-and-Timers/Dial-Timing-Relays http://literature.rockwellautomation.com/idc/groups/literature/documents/br/700-br020_-en-p.pdf |

When the light was on the pump was running (Doh!) and it was pretty easy to deduce that something wasn't right when the light was going on-off in a funny pattern. A simple delay switch might do the trick too. Bingo! Get a Vaportight outdoor wall fixture ('Jelly Jar' with a protective cage) and put a 4O Box up on a Rigid conduit riser over the well building (use a roof jack for the shingles) so you can see it from all around. Do NOT get the 'lantern' style Vaportight where the jar is pointed straight up - those depend on there being a good gasket at the base of the jar to keep the water out, worst case it runs down the inside of the conduit and does nasty things to your pump panel. With the jar mounted Open End Up gravity keeps the water out of the fixture, the gasket is only there for washdown circumstances. Put a Green or Amber globe on it, and a ~40W 130V A Lamp. It will catch your eye from anywhere when the pump is running, and if the light is blinking and fluttering you know something's up. You could add a second Red one and hook it to a pressure switch if it can't get enough pressure up - you might be overdrafting the well and it's running dry. Or better, you get a Warrick Relay (Warrick Controls Co.) - they have a low-voltage electrode that looks like a sparkplug, you drill and tap a hole in the side of the well output pipe. When the pump starts sucking air the detector electrode goes open to ground, and it will trigger the Warrick to shut down the pump until reset. If you get a deal on an 'Indicator Stack' light that's outdoor rated, go for it. You can then have a White indicator for Power On, Amber or Green for run, Red for Failure, and a Blue for a Heating Alarm - the pumphouse heater or stat has failed and it's below 45F in there. But then again, let's not... What am I saying?? R.C.M ALWAYS over-thinks these things!! -- Bruce -- |
