Depending on your current flow rate, you may be able to increase the flow simply by removing the filter or restricting device or replacing the showerhead with a higher-flow model, such as increasing to a standard 2.5 GPM head. Before you change the showerhead, make sure that the new model is legal in your area.
If you're experiencing low shower pressure, take these initial steps to find out what could be causing the problem: First, clean your showerhead thoroughly. Ensure the shower hose isn't kinked or damaged, then check the filter. This might require taking your shower apart, so consider asking a professional to help.
Low pressure in a shower can be caused by a number of issues such as a clogged up showerhead, a worn-out mixing valve, closed valve, leaking pipe, or even a faulty hot water heater.
For water conservation purposes, most plumbing codes require faucets and showering devices to not exceed a certain maximum flow rate. Removing the flow restrictors could cause these devices to no longer meet these codes.
Two big reasons: To help lower utility bills -- and to conserve water. According to the EPA, the average family could save 2,700 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy.
To compensate for variations in pressure, flow restrictors decrease the volume that water flows through when pressure increases. Likewise, the opening will widen when pressure decreases.
Removing the water restrictor from your showerhead can also improve water pressure. Removal might also clear out mineral build-up around the restrictor. It's fine for you to remove one if you live in an apartment unless otherwise stated. Note that your water bill may increase after removal.
Typical household water pressure in the US is between 50 psi~ 80 psi, therefore often times the actual flow rate out of the shower head would be less than the flow rate rating because they are rated at 80 psi and your house setting is likely not.
What does a flow restrictor look like? Before you remove the flow restrictor from your shower head, you need to know what it looks like. A water flow restrictor is usually a flat, circular, plastic piece. The center of the restrictor is shaped like a star, or similarly shaped, and comes in a variety of colors.
If you're looking for the most pressure, go for the 2.5 GPM Flow Rate, unless you are restricted because you reside in California, Colorado or New York. Again, this has been the Maximum Flow Rate since 1992. The step down from there in Flow Rate is 2.0 GPM.
Depending on your current flow rate, you may be able to increase the flow simply by removing the filter or restricting device or replacing the showerhead with a higher-flow model, such as increasing to a standard 2.5 GPM head. Before you change the showerhead, make sure that the new model is legal in your area.
Do All New Shower Heads Have Flow Restrictors? Not all new shower heads come with flow restrictors. While many brands focus on water and energy efficiency, it's not a universal feature. So, before you make a purchase, it's a good idea to check the specifications and ensure they fit your needs.
Anti-scald devices (also called a “hot limit stop” or “rotational limit stop”) are safety features that most faucets have. It's basically a “stopper” that limits how far your shower handle can rotate in the hot water direction.
Fluid flow requires a pressure gradient (ΔP) between two points such that flow is directly proportional to the pressure differential. Higher pressure differences will drive greater flow rates.
Relationship Between Flow Rate And Pressure Drop
The pressure drop is dependent on the flow rate, and vice versa. So if the flow rate is higher, the greater the pressure drop will be. Alternatively, if the flow rate is lower, the pressure drop will also be lower.
Open your main water valve.
Your house has a main water valve, usually located near the meter; the valve controls the flow of water into your home's pipes. Find the valve and check to see if it's completely open. Opening a half-shut valve is one of the quickest ways for increasing home water pressure.
GPM means Gallons Per Minute. Also known as "flow rate", GPM is a measure of how many gallons of water flow out of your shower head each minute. Since 1992, a maximum of 2.5 GPM is the federally mandated flow rate for new shower heads. This means no more than 2.5 gallons of water should flow out each minute.
U.S. government regulations limit the maximum flow rate of shower heads to 2.5 GPM as a measure to save water. Some places that experience droughts and water shortages have even tighter restrictions.
A 2.5 gpm shower head will have a better pressure and shower experience than a 1.5 gpm shower head. A 1.8 gpm shower head would have a better pressure and shower experience than a 1.0 gpm shower head. Another drawback of low flow shower heads boosting the pressure is the temperature instability.
Please keep in mind that all new faucets since 1994 are restricted to conserve water per EPA code mandates. Older faucets had no restrictions. Beyond intentional flow restriction, new installations can sometimes have reduced flow if the lines are not flushed prior to installation of aerators or shower heads.
The flow control valves are used for controlling and adjusting the fluid or gas flow through the system. The pressure control valve is used to regulate the pressure of a fluid passing through the pipe.
