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.
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.
Check Your Water Line & Valve
If your water valve is completely open, then check your water line and hoses. Flexible lines can easily develop kinks, so work those out to make sure that the water flow is smooth. If the water valve is partially closed, you'll need to open it so water can flow through your pipes easily.
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.
Will buying a new shower head increase water pressure? If you buy the right shower head it will increase how powerfully the water comes out of the showerhead even though it isn't actually increasing the water pressure of the home itself, it does increase the water pressure coming out of the showerhead.
A fast drop in only one faucet means there's a problem with the faucet. Rapid low pressure affecting one area of the house may mean a corroded pipe issue. An abrupt water pressure drop affecting the whole house may mean a water main break (municipal water) or a well pump problem (well water).
Put the showerhead in a bucket or plastic container and cover it with white vinegar. Leave it to soak in the vinegar for at least 30 minutes, preferably around an hour. Don't leave brass shower heads in vinegar for longer than 30 minutes. Take the showerhead out of the vinegar and rinse it with water.
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.
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. If your pressure gauge reading was low, make slight adjustments to your regulator.
If there's an accumulation of sediments in your hot water tank, it can lower your water pressure. The presence of kinks in the flexible water pipes used in water heaters can result in low water pressure. If the shut-off valve isn't fully open, water pressure can drop.
Check Your Aerator
If you have especially hard water, aerators become clogged with hard water buildup, a common cause of low water pressure in kitchen fixtures. Clean your aerator for a quick and easy DIY fix. Remove the aerator from the faucet using pliers and a towel (to prevent scratching).
Too much water pressure can be dangerous but low water pressure has an equal potential for being dangerous. Low water pressure could also mean that you have a clog somewhere in the system that you need to resolve. You want to do it fast because this can lead to issues with leaks that can cause water damage and mold.
Many people don't realize it, but shower heads should actually be replaced every 6 to 8 months.
What is commonly referred to as water pressure is determined by an individual home's water system, pipes, location and other elements. The goal became to create shower heads that provide the best shower experience possible, regardless of external factors.
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.
The adjustment screw raises and lowers the water pressure, but before it can be adjusted, you need to loosen the lock nut below it. Loosen the lock nut by half a turn with the crescent wrench. Turn the adjustment screw counterclockwise to lower the pressure or clockwise to raise the pressure.
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.
Removing a flow restrictor is illegal according to the US Energy Policy Act of 1992, which limits the maximum shower water flow rate to 2.5 gallons per minute (GPM).
The average US household can save about 2,900 gallons of water every year simply by installing a single low-flow showerhead.
