Well Water Pressure

Wondering what causes well water pressure problems? Go through this piece to find out why a well system may be delivering water at a low pressure.
People who live in a region which doesn't have a municipal water supply generally install a private well system. Though the well water pumps that are used in such systems are quite powerful, well water pressure may fluctuate sometimes. Low water pressure generally arises if you are running the water pump every now and then for multiple household tasks.
For instance, the shower head might have a low flow while the washing machine is drawing water. Wondering why does the water pressure peter out? Here's some information on the common problems associated with a well water system and what one can do to solve these problems.

What Causes Low Pressure in Well Systems?

When it comes to the water pressure issues, the size of the pipes, the capacity of the water pump and the pressure control mechanisms may have a role to play. A well water pump should be able to handle the water flow during the peak of your consumption period with ease. Take all the household appliances which you would use during that peak hour.
Then ascertain how many gallons of water are consumed by each appliance per minute. Sum all this up to get the consolidated water usage figure for your household. Can the water pump handle this? If not, then you need to look for an upgrade. The life of a water pump is also dependent on the pressure tank.
Any problem with the pressure tank could be responsible for the fluctuation in the water pressure. The pipes which carry the water all the way into your house must be of the right size. The right size should be determined by taking into account the present as well as the future requirements.

Water Pressure Problems in Well Systems

Water pressure problems in private well systems can generally be traced to the pressure tank. At times, the water lines may become flooded with air. Air tends to seep in during power cuts. This may happen when the water supply from your well has been turned off for long periods of time.
In such a scenario, turn the faucets on gradually so as to allow trapped air to escape. Water pressure problems can also be resolved by looking at the pressure controls. Shut off the main power switch and then open the pressure switch box.
Turn the large nut clockwise to boost the water pressure. Continue to turn this nut until you achieve the desired level of water pressure in your house. If you have never adjusted the water pump pressure switch before, it would be best to call in a plumber.
Also check the pipe quality. With the passage of time, the pipes of the water tank may get damaged or corroded. The water pressure would definitely be impacted under such circumstances. You will have to get them replaced. The tank on the well could become loose, thereby causing a big drop in pressure. This problem usually occurs when it's very humid.
If you live in a region with high humidity, you should check the tank. You would have to tighten the tank to set things right. Do check the connections that bind your well's water supply with that of the tank. A little tightening may be in order if it is loose.
Water pressure tank problems may also be the result of the well water pump losing its prime over normal use or after a power cut. The pump may then need to be checked. If the issue is serious, you might need to replace the water pump.
Check the pressure switch if the water pressure issue persists. Make sure that all the internal connections are in place within the pressure switch.
This was some information on the circumstances under which water pressure problems may arise in a well system. If the well system is not working properly, call a qualified plumber and an electrician to deal with plumbing and electrical issues respectively.
