How to Increase Water Pressure in your Shower

Few things are more frustrating than stepping into the shower, only to be greeted by a feeble trickle of water. Low water pressure can be a daily annoyance, making it difficult to enjoy a refreshing shower and slowing down your morning routine.

Fortunately, there are several expert tips and techniques that can help you increase water pressure in your shower. In this in-depth guide, we'll share eight expert tips to help you enjoy a satisfying shower experience.

Low Water Pressure in Shower

Low water pressure in a shower can be attributed to several factors, both within and outside your control. Common reasons include mineral deposits and debris clogging the showerhead and tap aerators, which restrict water flow. Plumbing issues such as pipe leaks, blockages, or corroded pipes can also diminish pressure. Additionally, a malfunctioning or partially closed water valve or pressure regulator can restrict the flow of water into your home.

In some cases, external factors like high demand on the local water supply or your home's location in an area with naturally low water pressure can contribute to the issue. We’ll help you identify the specific causes in your case so that you can find a resolution.

8 Expert Tips to Increase Water Pressure in Your Shower

Here are some effective ways that you can increase the water pressure in your shower:

1. Check for Clogs in Showerheads and Taps

One of the most common causes of low water pressure is the accumulation of mineral deposits and debris in your showerhead and tap aerators. The water that is supplied to your home usually contains minerals like limescale, which can get clogged up inside the shower head. The sediments are tiny but overtime they become attached to the shower head openings, which obstructs the flow of water.

To address this issue, start by unscrewing your showerhead and tap aerators. You can soak them in a vinegar or descaler solution to dissolve any buildup, but it is advised to only leave them for around an hour, and brass showerheads for only 30 minutes max. In the morning, rinse them thoroughly, brush any excess buildup away with an old toothbrush and reinstall them. This simple maintenance task can often lead to a noticeable improvement in water pressure.

It’s worth noting that our shower sets are specially designed to minimise limescale build-up via our patented cartridge system. Investing in a quality shower head early on can save you some serious headaches in the future.

2. Clean or Replace Your Shower Head

Over time, even with regular cleaning, shower heads can develop clogs that reduce water flow. If cleaning doesn't fully restore water pressure, consider replacing your showerhead with a high-pressure model designed to deliver a stronger stream. 

3. Inspect Water Valves and Pressure Regulators

Check the water valves and pressure regulators in your home's plumbing system. These components can sometimes become partially closed or malfunction, causing a drop in water pressure. Old valves tend to lose their grip overtime and slide shut due to the flow of water pushing it. Additionally, if you have just moved into a new home or have had a bathroom renovation, there is a chance that the main water supply valve is fully or partially closed.

If you're not comfortable checking your water valves or pressure regulators yourself, consult a professional plumber to ensure your plumbing system is operating at its optimal capacity.

4. Address Pipe Leaks and Blockages

The plumbing lines in a home are prone to leakage. Hidden pipe leaks or blockages can significantly impact water pressure throughout your home, even if the leak or blockage is small. You may not notice the leak or blockage elsewhere, apart from the reduced water pressure in the shower. Leakages in your pipes not only cause low water pressure but also increase your energy bills and over time, even impact the foundations of your house.

If you suspect a problem, it's crucial to have your plumbing system inspected by a professional. They can identify and repair any leaks or blockages, which may involve replacing old or corroded pipes.

5. Upgrade Your Water Pump

Homes in rural areas or locations with inadequate local water supply may rely on well pumps or booster pumps to maintain water pressure. If your water pump is old or undersized, upgrading to a more powerful model can make a significant difference in your shower's water pressure. Consult a pump specialist to determine the right pump size for your needs.

6. Install a Pressure-Boosting System

If all else fails, consider installing a pressure-boosting system, such as pressure-boosting pumps or whole-house water pressure boosting systems. These systems are designed to increase water pressure throughout your home and can be particularly beneficial if you live in an area with consistently low water pressure. However, it’s essential to note that these pressure-boosting systems are not compatible with combi boilers

7. Install a Shower Pump

Installing a shower pump can be an effective solution to boost water pressure and ensure a consistent and invigorating shower experience, especially in homes with inadequate natural water pressure or when bathrooms are far away from the main water pump of the house. However, it's essential to note that if you have a combi boiler, installing a shower pump is not advisable.

Combi boilers are incompatible with shower pumps because they are mains fed, and you can’t use a pump directly from the mains supply to provide a boost. Instead, if you have a combi boiler and are facing water pressure issues, you might want to consider installing an electric shower. Electric showers are connected directly to the cold water supply and can operate independently of the boiler, providing a consistent water flow and getting around the water pressure issue.

While installing a shower pump can be a viable method to increase water pressure, it might be an expensive option, and professional installation is advised. 

8. Be Mindful of Water Usage

Lastly, practice water conservation to ensure consistent water pressure. Avoid using multiple high-water-usage appliances (like washing machines and dishwashers) simultaneously with your shower, as this can lead to pressure fluctuations. Also, consider investing in low-flow fixtures for your sinks and shower heads to maintain good pressure while using less water.

FAQs on Ways to Increase Water Pressure in Shower

1. Why is my shower water pressure so low?
