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.
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.
Old pipes, especially ones made from metal, can corrode or rust from the inside. If mineral deposits are stuck in a water supply pipe, they can disrupt the flow to your shower (or other faucets). Similarly, if you have a small leak somewhere in your plumbing, low water pressure could be a noticeable symptom.
Most low-flow showerheads have a rubber pressure-reducing valve (called a regulator) to maintain a lower pressure. You can increase the flow by simply taking it out. You could also consider enlarging the hole that allows water into your showerhead with a drill to increase the amount of water coming through.
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.
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.
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).
If the water from your showerhead is shooting out in all directions, or your flow has become almost nonexistent, the holes in your showerhead are probably clogged with hard water minerals and soap residue.
Once you've installed your shower head, switch on the cold water supply and allow the water to run for between 10 and 15 seconds. After this, do the same with the hot side. If you are performing a shower valve test with air, simply follow the same procedure.
The shower valve plays a big role when it comes to your showering routine. The showerhead may be where water flows from, but the shower valve controls the water pressure and temperature to ensure an enjoyable shower experience.
Differentiating Between Low Flow And High Flow Shower Heads
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.
Shower and bathtub shutoff valves are usually hidden behind an access panel. That panel can be in the bathroom, the room behind the bathroom or the ceiling of the room below. If you don't have an access panel, it could be hidden behind the wall.
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.
You have leaks or drips
For example, water might seep out of parts of the valve; you may even see some water on the floor under it. This might indicate a faulty seal or a corrosion problem. If you have a TMV in your shower, then a faulty valve can make the shower drip even when it is off.
Clogged Shower Head
Usually, this is a result of a build up of calcium or lime scale. These mineral deposits build up over time, accumulating on shower heads. This often clogs the water coming from the shower head causing lower water pressure or even an entire stoppage of water altogether.
Showerheads clog over time because of a buildup of mineral deposits—specifically calcium. You may notice water spraying out of the nozzle in random directions, part of your showerhead is completely clogged, or poor water pressure.
The good news is that you can easily replace faucet aerators, clean showerheads to remove limescale, or simply buy new fixtures to replace the defective ones, which can improve your water pressure. However, it is important to know that repairing or replacing faucets and fixtures is only a temporary solution.
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).
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.
Step 1: Determine if the low water pressure is limited to your shower or if it's present throughout your home. You can do this by turning on various faucets and observing the pressure. If you notice the same low pressure everywhere… Your main water shutoff valve might be partially closed.
Do different shower heads affect water pressure? Yes, depending on which shower head you choose, they can increase the water pressure at the head itself in order to create a more powerful shower or decrease it to create a more gentle shower.
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.
