FAQs about the life expectancy of a water well:

Questins and answers on how long can a water well of different types (dug, driven, drilled) be expected to deliver a usable quantity of water.

This article series describes factors affecting the Life Expectancy of Drinking Water Wells & Water Tanks, answering the most basic question of: when will the well run out of water? We also discuss how to increase the well yield or water quantity without having to drill a new well.

On 2017-07-04 by (mod) re: loud flushing sound from well pump, piping


I'm not sure I can help much with out more information. But I can guess that there is air in your water piping or well piping.

If you use the search box above to find our article on AIR DISCHARGE AT FIXTURES you'll see the common causes and cures of that problem.

Let me know if that helps and we can proceed from there

My well pump, piping keeps on making a loud flushing sound.

On 2016-06-29 by (mod) re: diagnosing a clogged driven well screen and how to un-clog the point using acid products like Nuwell

Dave: your diagnosis sounds like a good guess.

The National Groundwater Association NGWA has published (unfortunately just part of) an article by David Schafer, "Less Time, Fewer Hazards with Pelletized Acid" (March-April 1971 in an un-named publication) that argues that this approach to clearing well screens can be effective. NuWell pelletized acid is (I think) provided by Johnson Hole Products, having offices across the U.S. and whose products are also distributed by plumbing & well suppliers.

According to the company
NUWELLTM 100 is a pelletized acid designed for pouring directly into the well. NuWell 100 is best for wells with short to moderate lengths of screen at the bottom.

I have a driven point well. I believe point screen has gotten clogged, you can pump water up but it seems to create a vaacum so pump runs longer. Runs out of water and then recharges. Can I put NuWell pellets in to hopefully unclog the screen? It's cheaper than $3000 for new driven point.

On 2016-06-29 by (mod) re: life span of galvanized vs pvc vs stainless steel piping for wells

Mohd, life span depends on the quality of the metal and the water chemistry, flow rates, temperatures and a range of other factors, so no single answer is absolutely right for all situations. Generally black ABS well piping has a very long life span; stainless steel has a longer life span than galvanized iron pipe if all other conditions remain the same and the pipe quality, thickness, gauge, workmanship, etc. are comparable.

On 2016-04-12 by (mod) re: water leaks out of well piping outside

First let's find the leak. If the leak is between well line and house, pulling the pump won't fix a thing.

Look for wet spots or if necessary try a few excavation points along the run of the well line between well and house. Or see if you can find a plumber with a small camera who can scope the pipe.

I have a water well that is more than 30 year old. Now, the water leaks to outside of house and cause the water pressure drop. The pump is currently in a cycle of running 20 seconds and resting 5 min even with no water usage.
I have been given 2 options from well-drilling company to fix the problem.
1. Try to pull the line and the pump/check valve out to replace them. It will cost 2k to 3k. I was told that it has a 75% chance that the pump cannot be pulled out. This will end up drilling a new well. We may not have water for 3 days or a week.
2. Drill a new well that will cost about 5K. The water outage will be short as a few hours for reconnecting the pipe to the new well.
My question is
1. What is the real chance for not be able to pull the pump out well and put a new one back in?
2. What is the best way to go?
Please advise.
Thanks, JZ

On 2016-03-19 by (mod) re: causes of sand and sediment sudden appearance in well water


- a cracked or damaged well casing
- failure of a well screen
- a change in the local water table
- loss of water flow into the well causing more pick-up churning at the well bottom

On 2016-03-19 by Terry

We are experiencing a huge amount of sand and sediment suddenly in our water. Enough to plug the water filters at the tank. What causes this?

On 2015-10-06 by (mod) re: typical warranty period or life of pressure tanks


Using Amtrol's well water tanks as an example, water tanks typically have a 5-7 year warranty period.

If your water tank uses an internal bladder (keeping water separate from the tank's air charge) and the tank has leaked I suspect that the bladder failed.

If your water tank does not use an internal bladder, water chemistry as well as the volume of water usage would be factors in the tank's life.

I have a water well thats six years old and the tank has rusted through ffrom the inside out and leaks. how long does tank last and should there be a warenty on it

On 2015-08-11 by (mod) re: pump keeps running


TURN OFF the system right away to reduce chances of ruining the pump.

At you will find the diagnostic procedure you need - found by searching InspectApedia for "Pump Won't Stop Running" - read that and let me know if questions remain.

On 2015-08-11 by Jerry

Residential , pressure gage will not go pass 30, and pump runs continuously even when water is off.

Question: minimum life of a water well

(Dec 9, 2011) shakeel ahmad said:
you must describe minimum life of water at least


Shakeel, there is no minimum life of a water well. An event can occur the day after a well is drilled or dug that causes it to become dry, while some wells have continued to function for centuries. The article above explains a number of factors that determine the life expectancy of a water well.

Question: well only works intermittently

(Feb 9, 2014) Eddie Pahlavan said:
I have a 45 feet well that works intermittently. While the contacts on the control switch are connected, the pump shuts off, while the pressure gauge stops at 30 or 35 (It usually ends up at 50). the pump start working at intervals, until the tanks fills up (usually in 10 to 30 minutes). while the problem is not the control switch, how can I proceed with diagnose the problem?


Eddie, why do you assume no trouble with the switch? Debris clogging can cause erratic switch behavior. Debris can also cause erroneous pressure gauge readings.

Tell us more about the intermittent pump startup. Is that occurring when no water is being used?

See WATER PRESSURE STOPS, RETURNS for diagnostics of this problem.

Question: why does our well water kill leaves on indoor plants?

Anon, bring a water sample to your local water test lab for analysis.

Question: Can a lightning strike crack our PVC water well casing

(Aug 13, 2014) Anonymous said:

Can a lightning strike crack our PVC water well casing - in three places?


Anon -
A lightning strike anywhere at the well casing or piping can send current that might damage piping in several locations. For example if water was changed to steam it might burst the piping.

Watch out: Before assuming that a water problem is due to the water pump or the water well itself.,
see WATER PUMP REPAIR GUIDE a specific case which offers an example of diagnosis of loss of water pressure, loss of water, and analyzes the actual repair cost.

If you know that your well is performing poorly with a poor flow rate or poor well recovery rate,
