Get a 1- or 2-liter carafe of water, a stopwatch and a calculator (the latter two you can probably get on your phone). Compare that to standard throughputs in the US. For the standard home, a typical GPM looks like this: Your water pressure also varies depending on where your home is at the nearest reservoir or water supply system. So, if you live on a hill, for example, your water pressure is likely to be lower as the water fights gravity to reach your home. On the other hand, if you live at the bottom of a hill, your water flow is likely to be much stronger because gravity helps pull it down the hill to your property. Water pressure determines how much water moves through your home`s pipes and out of your faucets or showers. The amount of tap water pressure you have depends largely on where you are in relation to the nearest supply, usually a tank. Water pressure can be measured in meters per capita, pounds per square inch (psi) or bar, 1 bar = 10 meters per capita = 14.5 psi. Normal water pressure is usually between 40 and 60 PSI, but most homeowners prefer to set it somewhere in the middle around 50 PSI. Once you`ve measured your home`s water pressure, you can adjust it to an ideal setting for all family members and household. Water pressure depends on your water tank and boiler. So, first of all, you need to know what water system you have and how it can affect the pressure and flow of water in your home.
Many whole-home filtration systems have been tested and certified NSF/ANSI to ensure your household has access to filtered water during peak hours or not. For example, our 600,000-gallon whole-house Rhino filter is tested and certified to reduce contaminants by up to 7 gallons per minute. The same goes for the 1,000,000-gallon Rhino Whole House filter – certified to reduce contaminants up to 7 GPM. Because at the end of the day, access to clean, filtered water shouldn`t mean you have to sacrifice a hot bath. In the water industry, we often have conversations that arise from the question: Which filter should I get? The answer really starts with a discussion about water. Often we have to talk about the different types of water that exist. High-performance water filtration reduces chlorine, lead and more from every tap for 1,000,000 gallons or 10 years. Water flow is usually measured in liters per minute, which is the amount of water that flows through a pipe or outlet in a given amount of time.
It differs from water pressure in that water pressure is a measure of the force to move that water through your pipe or outlet. A good example of this is when you compare two open pipe pipes that worked, both seemed to have a similar water flow. However, on the one hand, you can stop the flow of water by placing your hand on the end – the pressure is bad, on the other hand, if you put your hand on the end, the water overtakes it and creates a jet of water – the pressure is good. Another simple tip is to make sure you clean your showerhead, faucets, and pipes frequently to remove limescale, rust, or dirt. Just as your drains become clogged and slow down sinks or toilets, the same can happen to the water supply if it`s not cleaned regularly, resulting in lower pressure. Water pressure, on the other hand, is determined by gravity rather than speed. Your home`s water pressure is the force exerted on the water to get it from point A to point B. To test if your water pressure is too high (or even too low), a water pressure gauge can be used to measure the applied force of the liquid at rest. Water pressure in residential buildings should not exceed 80 psi, so if your meter shows above, you should call a plumber to have it examined by a professional. The pressure reducer takes a high inlet pressure and reduces it to a lower outlet pressure to compensate for your pressure problems. However, be sure not to turn off the faucet during installation, as this can lead to reduced flow and a noisy plumbing system.
Alternatively, you can have a rough guide by measuring the distance or drop between your water tank and the tap in meters (One meter = 0.1 bar) or buy a pressure gauge tool and attach it to a faucet for a more accurate measurement. When you begin your research process, look for a water filter that can handle at least 5 GPMs, and then consider your water quality, the contaminants you want to remove, and your budget. Do you just want to filter from your kitchen faucet? Or do you want to filter your entire house? The easiest way to check your water pressure is to contact your water utility or plumber, as they have commercially available tools to be able to check your water pressure. The second factor that affects your water flow is the square footage of your home. Determining your throughput per square foot can actually be broken down with a simple equation. For laymen, this equation determines the load capacity of your water filter, your media backwash rate, and also helps you understand if and when you`ll experience a pressure drop. The moment you put a bath bomb in the tub and try to relax at the end of a long day is the worst time to reduce your flow. But if you`re in a household of more than four people, or if your dishwasher is running while you`re bathing, then a drop in pressure isn`t just hypothetical, it`s a safe bet. Whether you use well or city water, your home water can contain many natural contaminants. If you have only one proper supply pipe, the first faucet in the house (this is usually the kitchen faucet) should be able to fill a 4.5-liter (one gallon) bucket in 30 seconds, along with all other faucets and appliances turned off. Another way to put it is enough water pressure to fill a cold water storage cistern in the attic of a two-story house.
Your throughput depends on a combination of factors, but the first one is the size of your household. The standard household size is 2 to 4 people. After four people, you are considered a “big cleaning”. This small difference in vocabulary makes all the difference when you`re trying to rinse your cup of coffee in the morning and not rinse it off. Some consider that a flow rate of less than 10 liters per minute is a low water pressure. Between 10 and 15 liters per minute is acceptable, but can be improved. A flow rate of more than 15 liters per minute is considered good. Checking your water pressure can be done in different ways, you can contact your water utility or a plumber, or you can test it yourself with a pressure gauge – most likely what a plumber would do. It is important to ensure that all faucets, showers, and appliances are turned off when you run the test so that your readings are accurate. It`s also a good idea to check your faucets and shower, as both are affected by the available water pressure. Water pressure is measured in “bars” to determine how far water should be pumped around your home. The basic measure for this is that a bar is the force needed to push water up to a height of 10 meters.
In general, anything at 0.3 bar or less requires a faucet or shower at low water pressure, and anything at 1.0 bar or higher requires a tap or shower at high water pressure. If you want to know where your water supply is coming from, check online with your local water authority, who can point you in the right direction. From there, you can determine if your property is higher or lower than the water utility`s, which indicates whether you are more likely to have high or low water pressure. A very easy way to increase your water pressure is to make sure your showerhead is at the right level. Your shower will not work as intended unless there is a minimum height of one meter between the shower head and the water level in the water tank of your accommodation. Known as the “water head”, the higher the head, the higher your water pressure will be. The typical water inlet pressure of a standard sized home is typically between 40 and 45 pressures per square inch (psi). For a standard household, it should never exceed 60 psi – which is why many plumbers automatically set their pressure regulator to 50 psi. But it`s important to remember that no matter how you set up your PSI, not all homes are standard. Therefore, pressure regulators can be changed between 25 and 75 psi without breaking a sweat. In addition, manufacturers have reduced the flow rate of showerheads over time.
If your current showerhead was manufactured in the 1980s or 1990s, your flow could be 3.5 GPM or higher. Thus, water pressure is the measure of the strength of water and water flow is the measure of water volume. However, the two are not completely separated, as good flow is often an indicator of good water pressure, as water flow usually improves as water pressure increases. An alternative method to the measuring jug is the purchase of a weir cup, you just need to place the spillway cup under the faucet or shower and turn it on completely. Water enters the top of the weir cup and flows through the side, where a scale indicates the flow of water from that particular outlet. However, keep in mind that the water pressure in each home is different depending on the domestic water system.
