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.
Pipe blockage, corrosion, or a leak
If you have low water pressure throughout your house and you've checked your internal stopcock is open, there aren't any water issues in your local area, you may have: A hidden leak. Blockage in your pipes. Corrosion in your pipes (can be common in houses with very old piping).
Apparent water pressure can be achieved by reducing the size of the holes or orifices in the shower head while maintaining the full volume of water being delivered. This can be achieved alternatively by increasing the whole house water pressure, which may not be advisable. Fewer holes allow more volume at higher rates.
Only your shower has low pressure? In most cases this indicates a fixture specific problem. If the faucet water has good pressure, but not the shower head, the shower head is likely clogged. If your shower head is old, it may be time to replace it.
Most shower valves are made of brass and located directly behind the handle of your shower or bathtub. This essential component opens and closes the hot and cold water lines headed to the shower head or tub faucet. Some showers have a single valve that handles both hot and cold water.
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.
You can tell if your shower valve needs to be replaced when the faucet is shut off but water continues to leak, the water temperature is difficult to control, there are random water temperature changes, or you notice decreases in shower water pressure.
You can increase water pressure in your home by cleaning showerheads and aerators, flushing your water heater, and clearing debris from your pipes. If these DIY fixes don't work, consider calling a professional plumber.
If you've been unable to identify the problem on your own, or if the issue requires a professional touch, such as a water heater repair or leaky pipes, it's time to call your favorite plumber. Not only will they get your water flowing again, but they can also verify that no other issues are at play.
If you're not sure if your shower head is low-flow or not, you hold a 1-gallon bucket beneath your showerhead, turn the faucets to the setting you would normally use, and see how long it takes to fill up the bucket. If it takes fewer than 24 seconds, it's not low-flow.
Flow restrictors are usually found in the neck or threaded end of the shower head exposed when the shower head is removed from the shower arm as shown in the image below. They would appear in the opening of the aerator when it is removed from a lavatory or kitchen faucet.
Drain clogs stemming from several common culprits are often the cause of low water pressure: Accumulation of hair, soap scum, and debris - Hair, dirt, grime, and soap deposits can gradually coat pipe interiors, contributing to low pressure over time.
Like testing your water pressure, you'll need a one-litre measuring jug and a stopwatch. Place your jug under the shower and turn it on. Then, time how long it takes to fill the jug. If it takes longer than six seconds to fill the jug, your shower is running at a low water pressure.
If you notice that your shower isn't dispersing hot or cold water, it may mean that your shower check valves are clogged. This video will show you how to clean them and restore the performance of your shower. For more home advice, please visit our help center: https://support.signat...
