We bought our house 6 months ago, found out our well is 305 ft deep, our neighbords (200 yards away) don't have water issues so I know it can't be dry and their well is shallower than ours. If we run our water for 45 min we will have no water in the house at all. (Like wash clothes and water veg garden) then we have to wait an hour or so for the system to fullback up and we will have water again. we have replaced the pressure set on our pressure tank and checked to make sure we had water in the well and had a plumber come out and make sure we had no leaks (he couldn't tell us what was wrong because he doesn't do wells 😒). Any idea why we could be running out of water?

  • Just because it's near another well doesn't necessarily mean you're getting the same water supply. Do you know how deep your pump is sitting? If it's not at the bottom it indeed possible it can pump the water level down to the pump. There's really only two ways to tell for sure: inspection camera or pull the pump up (and warning: 305ft is a very heavy pull, highly advise using pros or at least a few people and someone that's pulled pumps before). – gregmac Jul 24 '17 at 21:52

200 yards is a long way when it comes to drilled wells. I'm probably that far downhill of one that is filled to the top, and mine has a static level 100 feet down. Your neighbors may also use water differently than you do.

You appear to be overpumping your well (taking water out faster than it flows in) - You evidently have one piece of data (305 foot depth) but lack many others: depth of pump setting, information about the pump, flow-rate measured at time of drilling the well, static water level, diameter of well - some of those you may be able to gather, or find from the company that drilled the well in the first place.

On your own, you can shut off everything that uses water, wait a while (preferably several hours or more) to let the well fill to the maximum static level, and then fill buckets as fast as possible to try and determine what your effective storage capacity above the pump is. When the well stops, wait an hour and repeat, and THAT will tell you the effective refill rate:

If you pull 200 gallons the first time and 50 gallons the second, you are getting 50 gallons per hour (more or less - since time passes as you fill the buckets) - which is less than one gallon per minute. That can be plenty of water if you don't overdo it (watering the garden can take a LOT of water, depending how you do that - changing to drip irrigation might cut down the rate of use a lot, .vs. sprinklers, say) and have reasonable storage capacity ( in this hypothetical example, the first 200 gallons, or 4 hours with of inflow) to allow for washing, bathtubs, and refilling toilets, etc.

If you require more flow than your well provides and any water conserving measures you are willing to take are not enough, you can have the well worked on by a well-drilling (or well-servicing - often the same, but not always) company in various ways - hydrofracking being perhaps the most trendy (pumping in high-pressure water to open up cracks in the rock to allow water to flow in faster) - unfortunately, it's usually fairly expensive and results are generally not guaranteed.

  • I would look at the pump overheating first old submersible pump over heating and tripping its thermal overload is a common occurrence. – Ed Beal Jul 25 '17 at 0:32
  • While sitting in 52°F/11°C water? When run dry they should shut down (preferably long-before overheating, but it depends on the controls setup.) Have not personally seen much of submersible pumps overheating in a well with sufficient water in it. Perhaps in a geothermal hot-spot that would be more common... – Ecnerwal Jul 25 '17 at 1:24
  • I have seen many pumps that are failing trip there internal overload. When the bearings start to fail the motor overheats. BTW a sumersible pump in an ice bath can overheat if the motor is close to locked rotor had that happen on a process bath. – Ed Beal Jul 25 '17 at 2:19

You may be exceeding the flow rate of the well. I have seen wells within 100' have vastly different rates. Another possibility is your pump is overheating and shutting down. Did you have a flow test on the well when you purchased the property many loans require 5 gallons per minute for 2-3 hours. A person that performs flow tests can check your water level by dropping a meter down the vent, when they hit water they check the distance.

  • There are also sonic water level meters that don't involve the risk of tangling anything up in the pipe and wires - they just send a "ping" down the well and wait for the echo, converting that to a depth to water surface.) Hmmm. I wonder if there's a phone app for that... – Ecnerwal Jul 25 '17 at 0:10
