Many modern shower heads are designed specifically to increase the pressure of the water coming out of the showerhead itself. So, while they can't increase the actual water pressure of the home, they do improve the showering experience.
The most common cause of low shower pressure is a blocked showerhead, as a result of limescale build-up. These blockages obstruct the water flow, leading to reduced pressure over time. Most showers are fitted with a filter, protecting the pipework from debris, but this can become partially blocked by scale.
Restrictive valves on the showerhead: A low-flow showerhead may have been fitted to your shower, or your showerhead may have a valve that restricts the flow of water. These restrictors are put in place to help save water. However, sometimes they may limit it too much.
When shopping for shower heads, be sure to compare “apples to apples.” A 2.0 GPM shower head simply will not reproduce the flow rate of your old, 3.5 GPM shower head. Know the Laws. Depending on where you live, retailers may only sell shower heads with a maximum of 2.5 GPM, 2.0 GPM, or 1.8 GPM flow rate.
But when it comes to upgrading your shower routine to make it feel a bit more special, think beyond just the products you're using — like changing out the hardware in the shower itself. Swapping out a run-of-the-mill shower head can make a huge difference when it comes to your time spent under the spray.
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.
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.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter.
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.
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.
If you've just installed a brand-new showerhead and find that the pressure is suddenly lower, it's probably because you've purchased a water-saving showerhead. Check the labels around the rim, or perform the showerhead GPM test as described below.
One of the simplest reasons for the lose of shower pressure is a blocked shower head. Shower heads accumulate mineral residue when the shower head is in use. Once the water has been shut off, over time these mineral deposits will bond together and create a limescale build up inside your pipes or shower head.
Pressure-Reducing Valve
Look on the main supply pipe near your water meter for a conical valve that has a bolt sticking out of the cone. To raise pressure, turn the bolt clockwise after loosening its locknut. Keep an eye on the gauge to make sure the pressure is within bounds, then retighten the locknut.
The short answer is low water pressure in your home arises due to a number of causes. Some include a shut or blocked water meter valve, mineral buildup clogs pipes, corroded pipes, or even a crack in the main city supply pipe to your home.
The Fire Hydrant Spa Shower Head Spa Plaza is a good replacement shower head that is designed to boost water pressure in low flow settings. It has a 4-inch face to provide wide coverage, and this enables the water to reach all parts of your body.
Many people don't realize it, but shower heads should actually be replaced every 6 to 8 months.
When it comes to Shower Heads, you'll typically find 2.5 GPM, 2.0 GPM, 1.8 GPM and 1.5 GPM. 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.
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.
A standard 2.5 GPM shower head uses 2.5 gallons of water each minute. That's 25 gallons for a 10-minute shower. VS. A low-flow 1.8 GPM shower head uses 1.8 gallons of water each minute.
The center of the restrictor is shaped like a star, or similarly shaped, and comes in a variety of colors. It's found behind where the shower head screws off of the pipe coming out of the wall or at the end of the flexible hosing of a handheld shower head.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.
