Tired of a Weak Shower? Here’s How to Fix It
When it’s time for a shower and there’s no water coming out, it’s very disappointing. Low water pressure in the shower is not only annoying, but it can also indicate underlying plumbing problems that could worsen over time.
At UR Plumber, we help people identify and resolve all water pressure issues. It could be caused by old pipes, an outdated hot water system, or even a hidden leak.
This guide will show you how to increase water pressure in shower. It will also help you know when you need the help of a plumber.
What Causes Low Water Pressure in Showers?
Before buying a pressure pump or calling a plumber, it is good to know the cause of the problem. Here are some reasons why a shower has low water pressure:
- Old or rusted plumbing pipes are restricting the flow of water.
- There is a leak in the plumbing system.
- Low water pressure in the house supply is due to a gravity-fed hot water cylinder.
- Or perhaps the main valve is not fully opened.
- Old hot water cylinders
- Clogged showerheads and taps
- Hidden leaks
- Set the wrong pressure-reducing valves
- Council pressure limits
Note: Older systems may have limits in place to prevent bursts. Check with pros for adjustments.
Tips for Low Water Pressure in Showers
Clean the Showerhead
Limescale can block showerhead nozzles. Soak in vinegar, scrub, & use a pin to clear. Get a high-pressure showerhead if too clogged.
Check Pipes for Kinks/Leaks
Small leaks hurt shower pressure. Inspect visible pipes and flexible hoses for leaks or kinks. Repair or replace as needed.
We find leaks behind walls using pressure tests & thermal imaging.
How to Increase Hot Water Pressure from Cylinder Systems
In New Zealand homes, low-pressure cylinders give poor water flow in showers and sinks.
Options to Improve Hot Water Pressure:
- Get a mains pressure cylinder – it provides a strong flow to all taps.
- Have a pressure booster pump – for budget or rented homes to boost flow at a low cost.
- Check the tempering valve – a setting that is too low stops the hot water.
Adjust the Mains Pressure Valve
The PRV at the main water meter protects the plumbing, but if set too low, it reduces pressure in the house.
Only a qualified plumber should adjust this valve to avoid pipe damage.
Install a Shower Pressure Booster Pump
Booster pumps are compact devices that increase water flow directly to your shower. These are especially useful for:
- Mains pressure hot systems
- Mains pressure when taking a shower
- Showering with strong hot water flow
Plumbers offer efficient energy-saving pumps for enhanced showering performance.
Upgrade to Mains Pressure Hot Water Systems
Upgrade from gravity-fed cylinders and get mains pressure hot water systems. It provides a steady water flow everywhere at home – in showers, sinks, laundry, and even outside taps.
We help replace outdated systems with efficient new cylinders for better energy saving and water flow.
How to Increase Water Pressure in New Zealand
Pressure issues differ in city and rural areas due to local setups, home heights and plumbing systems.
We conduct site checks using flow tests and pressure gauges to determine the root cause of your issue before suggesting affordable solutions.
Check for Outdated Plumbing Systems
Old galvanised pipes cause trouble in NZ homes as they rust inside, reducing water pressure. This is a common issue for many houses built between 1960 and 1980. If your pipes are older than 40 years or are still made of outdated materials, consider replacing some or all of them with newer PVC or PEX piping.
Balance Water Usage Throughout Your Home
If the shower pressure decreases when using appliances (such as flushing toilets or running dishwashers), there may be problems with the pipe size and distribution of water flow.
Try these solutions:
- Install pressure-balancing valves to ensure constant flow
- Change narrow pipes for larger ones
- Use high-demand appliances at different times from showers
Replace or Service Your Pressure-Reducing Valve
Pressure-reducing valves (PRVs) older than 10 years may wear out or accumulate deposits that impair their performance. This leads to pressure issues, even when the settings appear to be correct.
Consider a Continuous Flow Hot Water System
Continuous flow units heat water only upon request instead of storing it in tanks. They save energy, take up less space, and work under the central pressure, too.
They are excellent for newer homes or places where water consumption varies significantly at times, providing endless hot water while delivering intense shower experiences.
Conclusion
Strong, consistent shower flows can be restored through simple remedies like unclogging shower heads, although complete system upgrades may be necessary. You should no longer endure weak shower performances!

Frequently Asked Questions
How do I increase water pressure in my shower in NZ
Start by cleaning the showerhead, inspecting it for leaks, and verifying the pressure valve setting. If pressure remains low, consider upgrading your system or installing a booster pump. We can help you assess and address the issue.
How to increase hot water pressure from the cylinder without replacing it?
Adjusting the tempering valve or installing a pump. These are less invasive and budget-friendly options.
Can I increase hot water pressure with a pressure pump?
Definitely! Pumps work well when upgrading the cylinder is impractical. They are quick, efficient and can be discreetly installed.
Why is my shower pressure lower than other taps?
This is often due to a clogged showerhead, a separate pipe issue, or the shower connected to a low-pressure line or cylinder.
How much does it cost to increase water pressure in NZ?
Simple fixes are low-cost or DIY. Booster pump or cylinder upgrades are pricier but provide long-lasting value. We always give clear quotes.
