Why Does My Shower Lose Hot Water When Someone Turns On the Tap?

There’s nothing better than ending the day with a long hot shower and washing away a hard day’s work. However, if your hot water supply is suddenly interrupted by someone using the kitchen sink, that relaxation can be cut short. Many things can have an impact on the supply of your hot water. All the water pipes and fixtures on your property are connected. This sometimes means, when the water pipes run simultaneously, or other water sources are in use, such as the laundry or even the toilet flushing, loss of heating to your shower can occur.   

Being aware of how your home plumbing system functions is vital to understanding this issue. For example, water is being distributed around the property constantly to various fixtures and fittings, such as taps, sinks and toilets. This means that when another fitting such as a tap uses hot water whilst the shower is running, the hot water supply will be taken from the shower and pumped into the pipe that leads to that tap—leading to the sudden interruption of cold water experienced.  

So, how can you fix this problem?

There are many options to choose from when wanting to preserve the hot water supply in your shower.  

Water flow from shower head in bathroom

Installing water-efficient taps in the bathroom: 

Water-efficient taps allow the speed of water travelling through your pipes to slow down. Now, we understand that replacing the faucets in your shower can be a hassle, so instead, you can opt to install an aerator. Aerators are attached to the tip of the tap head and, as the name suggests, add air to the water stream, limiting the flow of water through the faucet.  

Water-saving showerhead: 

Water-saving showerheads and water-efficient taps are similar in that the showerhead reduces the pressure of the water through the use of air bubbles. It can be attached to the top of the showerhead and removed when desired. We believe that water-saving attachments such as showerheads and faucets are one of the most accessible and affordable plumbing solutions for this issue whilst also helping to regulate water usage, benefiting the environment.   

Correct Pipework 

Incorrect installation of pipework within your home can lead to an insufficient hot water supply. This can also lead to inconsistencies with hot and cold water temperatures. This can be checked and serviced by a licensed plumber. Contact us today to organise a visit to your property.  

Using one fixture at a time: 

This method is pretty straightforward. To ensure the hot water supply to your shower is not interrupted, refrain from using multiple fixtures at one time. Prioritising fixtures is the easiest and most cost-effective option to combat this issue.
