At Dublin Shower Pumps, we know how important it is to have steady, reliable water pressure in your home, especially when it comes to enjoying a good shower. If the water flow suddenly drops or surges, it’s not just annoying—it could be a sign of a bigger issue.
In this guide, we’ll walk you through how to check water pressure at home in a simple, practical way. Whether your shower’s gone weak or your taps are blasting too hard, knowing how to test your pressure is the first step to fixing the problem. And if you’re in the Dublin area, we’re always here to help with expert support and installation.
What Is Water Pressure?
Water pressure refers to the force that pushes water through your pipes and out of your taps and showerheads. It’s measured in bars, with most homes in Ireland needing between 1 and 3 bars for everything to work smoothly. Too low, and your shower might feel more like a drizzle. Too high, and you could be putting unnecessary strain on your plumbing and shower pump.
If your water pressure isn’t in the right range, it can affect everything from your shower experience to how long it takes to fill the washing machine. Understanding what’s normal makes it easier to spot when something’s off.
Signs Your Water Pressure May Be Off
Not sure if you need to test your water pressure? Keep an eye out for these common signs:
Weak water flow: If your shower suddenly feels underwhelming or your taps take forever to fill a sink, you might have low pressure.
Excessive force: On the flip side, water blasting out too hard can also be a sign of high pressure.
Noisy pipes or rattling sounds: Unusual noises when using water could point to pressure fluctuations.
Inconsistent flow: Pressure that changes from strong to weak during a shower or while using appliances is a red flag.
If your shower pump is acting up with odd sounds even when not in use, it could be pressure-related. Have a look at our guide on shower pump making noise when not in use to see what might be causing it.
How to Check Water Pressure at Home
Checking your water pressure at home is easier than you might think. Here are two methods you can try:
Method 1: Using a Pressure Gauge
Turn off all taps and appliances that use water.
Attach a pressure gauge to an outdoor garden tap or kitchen tap (you may need an adapter).
Turn the tap on fully.
Read the gauge—most homes should register between 1 and 3 bars.
Method 2: The Jug and Timer Test
If you don’t have a gauge:
Take a 1-litre measuring jug and place it under your kitchen tap.
Turn the cold tap on full and time how long it takes to fill the jug.
Less than 6 seconds = good pressure. More than 10 seconds = pressure might be too low.
Once you’ve tested your pressure, you’ll have a clearer idea of what’s going on. If it’s outside the normal range, your system could benefit from adjustments—or possibly a shower pump installation.
What to Do If the Pressure Is Too Low or Too High
If your test shows water pressure that’s either too low or too high, it’s best not to ignore it—both can affect your plumbing and appliances.
Low Pressure
Low pressure can result from:
Blocked pipes or valves
Issues with your mains supply
An undersized or faulty pump
Installing a shower pump is often an effective way to boost pressure, especially for upstairs bathrooms or power showers. It improves flow without overloading your system.
High Pressure
While strong flow might seem like a good thing, water pressure that’s too high can wear out pipes, fittings, and appliances over time. A pressure-reducing valve or system balancing might be needed.
Managing pressure isn’t just about comfort—it can help save energy too. For example, if you’re constantly turning up your electric shower to compensate for poor flow, you’re likely using more energy.

Preventing Common Shower Pump Issues
Maintaining steady water pressure not only keeps your showers consistent—it also helps prevent common pump problems. Sudden drops or air in the system can cause a pump to run dry or make loud noises.
One of the most frequent issues we deal with is airlocks, which can happen when air gets trapped in the pipes and restricts flow. This often leads to noise or your pump cutting out.
The good news? It’s preventable. For a quick guide, visit our page on how to prevent airlocks in the shower pump.
A well-maintained system with balanced pressure reduces the chance of wear and keeps your pump running smoothly for years.

Frequently Asked Questions (FAQ)
For most homes in Ireland, normal water pressure should be between 1 and 3 bars. Anything lower may affect your shower performance, and anything higher could strain your pipes or appliances.
Yes, you can use a simple jug and stopwatch method. If it takes more than 10 seconds to fill a 1-litre jug from your kitchen tap, your pressure may be too low.
Low pressure can be caused by partially closed valves, blockages, old pipework, or a weak mains supply. It can also result from a faulty or missing shower pump.
Yes. While it may seem helpful, high pressure can cause long-term damage to plumbing fixtures, lead to leaks, and reduce the lifespan of shower pumps.
We recommend testing every 6 to 12 months, or whenever you notice changes in water flow or pressure. Regular checks help prevent problems before they escalate.
