About Water Pressure

Water pressure is an important feature of how we live and how we function within our daily activities. The pressure of water as it comes out of our spigots can affect many things including how fast we can shower and how quickly our clothes can be washed.

About Water Pressure

Learning ways to improve water pressure will assist in making life and daily household tasks easier.


Water pressure is determined by how many pounds per square inch (PSI) is being utilized through a water system. Water pressure is important for appliances and household items such as dishwashers, washing machines, toilets, showers and water softeners to be able to function efficiently and properly. If a public water system is being utilized, many times water pressure is high---or over 75 PSI. With a high water pressure most items in the house are able to be used effectively and pressure is able to allow it to push out a large amount of water flow.


Water pressure is generated by either a natural flow such as an ocean, river and natural tributary which feed artesian wells or waterfalls that overflow into other water sources. A steady flow or amount of water pressure can also be created by pumps within the city water system or with a water pump inside a home to pressurize his and force water through pipes where water needs to be utilized. Water pressure is important for pushing through particles or clogs that may form within drains and keep a clear path of flowing water. Many appliances will not work if the water pressure is to low, for example a water softener cannot regenerate itself if the pressure is not above 60 PSI. A fire hydrant can not extinguish water if the pressure is minimal or down to a trickle at around 10 PSI.


For natural pumps or water springs, a trickle or slow flow create minimal water pressure when not pumped by a hand pump or a natural form of water pressure such as a flood or river dumping into the water source. Garden hoses that are over 25 feet long could see a significant reduction in water pressure due to the fact of how far the water has to travel from the pump or pressure source. People with shallow wells generally use a submersible or jet pumps. Submersible are designed for extremely deep wells at around 500 feet and force the water to the surface plumbing of the home. Jet pumps are above the ground and come in either shallow or deep types. The shallow water well pump is perfect for wells that are less than 25 feet deep and the deep well is created for those over 25 feet and the water is pumped into a holding tank and then pressurized to produce a steady flow of water into the pipes of the home.


The closer an appliance is to a natural water pump or a man made pump the higher the water pressure will be. If a home is a great distance away from a main water pump within a city water pipeline, the water pressure will be less than those who live near the water station. If more people hook into a public water system, less pressure will be received through the lines at each residence. If using well water with a water pump, when multiple sources begin pulling from the pump such as a washer, dishwasher and water softener at the same time as someone happens to be in the shower they will have less water pressure than if those appliances were not operating.


For low PSI or water pressure in homes, one first must find the source of low pressure. For those who utilize their water source from their own well, replacing their pressure tank that is attached to pump may be the answer. Buying one that stores more water and provides greater pressure will help more water flow throughout the water lines into appliances. Checking to see if there is excessive hard water or lime scale buildup in water lines may also be the answer or the water lines may need to be replaced. A water softener system will help eliminate rust and hard water buildup which can clog lines and make water pressure seemed slow and sluggish.
