Do Whole House Water Filters Decrease Water Flow?

The whole water pressure filter can reduce the water flow in your plumbing systems. Water flow depends on the pressure exerted on the water.

Therefore, since an entire house water filter can reduce water pressure, it will also affect the water flow.

Pressure is reduced by using the incorrect size of pipes in your plumbing system and clogging in your filters. Once pressure is reduced, the water flow in your home will decrease.

Understanding The Flow Rate And Water Pressure Formation

Understanding water pressure and water flow are essential to diagnose why the water filter system in your household is experiencing a pressure drop.

Water pressure and water flow may look similar on most occasions and confuse many. However, for those who understand, water pressure and flow are two completely different things.

Let’s find out what they both mean and how they are, and the impact they have on your plumbing system. Water flow otherwise can be flow rate, which is the amount of water that flows through a given outlet per unit of time.

The units of measurement of water flow in gallons per minute. Keenly monitor how water is ejected from your faucets to see any fluctuation in water flow.

Also, you can measure this phenomenon on your own by leaving the tap fully open, placing the cup beneath it, and after measuring time accurately, closing the tap.

Multiply the number of cups with its capacity, convert them to gallons, and divide by time. On the other hand, water pressure is the force behind the flow of water.

It can be defined as how much force pushes water through a faucet. Often, pressure is created by using the height and weight of water. This pressure is sufficient to distribute water to the entire delivery system.

Once allocated to households, water pressure is delivered via a pressure regulator. However, if you are using groundwater, you are wondering, how is my water pressure created or regulated?

A good pump is behind your water pressure. The good pump works in conjunction with additional booster pumps or a pressure tank to develop and maintain constant pressure.

Now you know how different water flow and water pressure are. How do they operate? The pressure exerted on the water is very much related to water flow. When the pressure exerted on the water is high, then the flow of water is high.

On the other hand, a low-pressure water filter can result from intense pressure delivery. They are not the same, but water pressure significantly impacts water flow.

Usually, Pressing Need To Remove Toxins From Water

Using clean and healthy water is essential. Therefore, eliminating water contaminants is necessary for the well-being of the household.

Water always contains toxic chemicals such as fluorides and other heavy metals that need to be removed for water to be considered safe.

Currently, most people use water from plastic bottles. Although it can be considered safe depending on the treatment method, the heap of waste plastic bottles from bottled water is alarming.

For that reason, a large population finds it suitable to shift to using water filters. Water filters come in different calibers but effectively eliminate the contaminants found in water, such as fluorides and heavy metals.

Among the trusted water filters include reverse osmosis and carbon filtration systems. However, these filters can lead to dropping in water filter pressure.

The outbreak of waterborne infections puts pressure on communities to find effective water filtration mechanisms. Therefore, having an effective house water filtration system in your household is essential to be on the safer side.

What Are The Factors That Influence Water Pressure And Its Flow?

Are you wondering why your water pressure and flow are low and high sometimes and how to reduce filter flow? Water pressure and flow are significant for every household.

If your water pressure might be high or low, factors lead to that. Below, I have covered for you factors that primarily affect the rate at which water flow and its pressure around your household.

Water Demand/Requirement

Water demand refers to the amount of water required to carry out everyday activities. The demand for water in your family can be one of the main factors influencing the pressure and flow of water around your home.

To understand how you should pay attention to the amount of water you consume per day and monitor the flow. How does water demand affect water pressure drop in houses?

A household with a high water demand tends to consume much water per time given. Therefore, an increase in water requirement around your home is likely to lower the water in your reservoirs.

This phenomenon will lead to water pressure drop and, consequently, water flow since the two go hand in hand. On the other hand, a household with a bit of water demand will experience high pressure and hence water flow.

The reason behind it is reservoirs hold water for an extended time. Therefore, more pressure is exerted on water, and thus, water flow increases.

Water Quality/Type

The water type affects the water pressure and flows by its contents. For instance, the minerals and salts in the hard water are responsible for clog formation within pipes.

Clog formation will translate to a decrease in water pressure and flow. Soft water, however, passes through pipes without causing clogs. Therefore, the pipe size is not affected. A pipe without clogs will have sufficient water pressure and flow.

Time of The Day

The time of the day is critical in water pressure and flow around your home. This is evident from the fact that there is high demand for water at times and low demand at other times.

During peak hours, more water is required, and thus water pressure is low, and so is the water flow. When it comes to odd hours, there is little demand for water, and this ensures that more water is available for use.

When more water is open, water pressure goes up. Since water pressure and flow are related, an increase in pressure translates to a rise in its flow.

Different Water Outlets Running At The Same Time

Have you ever opened two or more water outlets in the same household? What happens? Exactly, when more outlets are left running, the pressure and water flow are low compared to when one outlet is left open.

The reason behind this is that, as more outlets are left running, each one takes a fraction of the pressure and flow of water. When only one outlet is left running, all the stress and water flow are channeled to that particular outlet.

Fault Size of Pipes

Getting the wrong size of pipes around your plumbing system will significantly affect your water pressure and flow. The pipes in your system should correspond to the water demand in your household.

Pressure is usually the victim of having smaller pipes against your water demands. Also, clogging within pipes will affect the size of the pipes, and more often than not, they harm pressure limiting the water flow.

Home Height/Ceiling

While some houses have lengthy heights, others are shorter. How does the height of the home affect the water pressure in your household?

For more transient houses, water takes a short time to reach the outlet; therefore, the pressure exerted on the water is evident when the flow of water is high.

Conversely, water takes longer to arrive at the outlet with lengthy heights. Therefore, the pressure exerted on the water is reduced when water runs out of the outlet. A drop in water pressure and flow is experienced in more extended heights.

Filter Quality

In every product, quality is paramount for its performance. A water filter that will give excellent results will automatically be of excellent quality.

The water pressure and flow of your home are dependent on the quality of the filter you have. You are guaranteed ideal water pressure and flow for a quality water filter.

However, if you don’t pay attention when selecting the right filter for your home, you might land on a low-level filter which will give you low water pressure for the whole house.

The Flow Rate of The filter

Different filters are made in a way that accommodates different types of pressure. Selecting the water filter with the desirable water flow for your home is essential for your home.

A water filter with a high flow rate is most likely to have a high pressure compared to the filters with a low flow rate.

If you have a high demand for water, a high-pressure water filter is ideal for your home. The low demand for water requires filters with a low flow rate.

Formation of Your Choice For Whole House Water Filters

Typically, everyone wants what is best for their home. You ensure that your household has access to the safest and healthiest water possible when it comes to water.

However, it does not happen overnight; there are things to consider before setting off to buy a water filter for your home.

An ideal whole house water filter meets your requirements and gives you comfort in the water you consume. Below are vital factors to consider to get the best whole house water filter.

What Does It Filter Out?

There is a wide range of contaminants that require removal from water. Therefore, understanding the contents to be eliminated in your water is crucial when choosing a filter for your household.

Standard water filters only remove taste, chlorine, dust, and poor smell in water using activated carbon fiber filters. Now you wonder how heavy metals, fluorides, and other contaminants are.

Don’t scratch your head because other filtration systems such as reverse osmosis effectively eliminate a high range of contaminants making your water the safest to consume.

Once you understand the type of water you use and its contaminants, it shouldn’t be a big deal to choose the water filter that fits your household requirements.

Is It N.S.F. Standards?

National sanitation foundation (N.S.F.) is a body tasked with ensuring all the water filter solutions in the market maintain high standards. N.S.F. ensures that your filter solutions are safe to handle the water you consume.

Therefore, knowing the body that certifies the best water filter solutions, you should consider getting a filter that meets N.S.F. standards. Having such a filter gives you top-notch performance around your household.

A whole house water filter system attains N.S.F. standards and uses a heavy-duty polypropylene cartridge essential in reinforcing filter containers. Filters with polypropylene meet N.S.F. standards and have F.D.A.’s approval.

Need Attention To The Filter Life

The life of your whole house filter is critical. You don’t want to be ordering filters like groceries. Installing an entire house water filtration system is a complex and time-consuming process.

If you are not used to handling your plumbing system, you will have to engage an expert since even the simple filter cartridge requires expert skills to install, fix and replace.

Getting a long-lasting water filtration system is vital to avoid the hassle of all these. Having a water filtration system that is not durable will have you replace the filters quickly.
