Low Pressure in Your Upstairs Shower? Here’s What to Do
Why Upstairs Showers Often Have Low Water Pressure Let’s be honest — few things are more annoying than stepping into your upstairs shower and getting barely more than a trickle of water. If you’re dealing with low pressure in upstairs shower, you’re not alone. It’s a common issue, especially in older Dublin homes with traditional gravity-fed plumbing systems. Most of the time, the problem comes down to basic water flow physics. The higher your bathroom is from the water tank, the harder it is for the water to reach it with enough pressure. That’s why upstairs showers are often the first place you notice weak flow. At Dublin Shower Pumps, we see this a lot. Whether you live in a terraced home in Clondalkin or a two-storey house in Dundrum, water pressure upstairs can be a real issue — but the good news is: it can be fixed. Signs Your Upstairs Shower Has a Water Pressure Problem Here are a few signs that you’re dealing with low water pressure — especially upstairs: Your shower head barely sprays, even when turned fully on It takes forever to rinse shampoo or soap The water flow weakens even more when another tap is running You hear humming or vibrations when using the shower If any of this sounds familiar, it’s a good idea to have a proper look at your setup. In some cases, it might be something simple — like an airlock. You can learn more about that in our guide on how to prevent airlocks in your shower pump. But in many situations, especially when the issue keeps coming back, installing a shower pump might be the most reliable solution. What You Can Try Before Calling a Technician Before jumping into a full installation or upgrade, there are a few simple things you can check yourself: Make sure your isolator valves are fully open. These small levers control the flow of water to different parts of your home — sometimes they’re partially closed without you realising. Clean your shower head. Limescale build-up is very common in Dublin water and can make the pressure feel weaker than it really is. Check for trapped air. If you hear gurgling or the water spurts out unevenly, it could be an airlock in your system. If your low pressure in upstairs shower isn’t due to a blockage or valve issue, chances are your home’s water system just isn’t strong enough on its own. That’s where a professional solution comes in. When a Shower Pump Is the Right Solution In many Dublin homes — especially ones with older gravity-fed systems — water simply doesn’t have the force it needs to reach your upstairs bathroom at a usable pressure. That’s where a shower pump comes in. A shower pump works by boosting the flow of water between your hot water cylinder and your shower, giving you a stronger, more consistent spray. It’s a straightforward and highly effective fix for low water pressure in upper floors. We often recommend this option when: The bathroom is on the top floor and far from the tank The home has an older heating/plumbing layout You’ve already tried cleaning and checking for airlocks We work with trusted, quiet-running pumps from brands proven to handle Irish water systems. If you’re unsure what type is best for your setup, have a look at our guide on the top brands for shower pumps, which covers reliable options based on home size and layout.
