Imagine you’re coming home from a long day, and all you are looking forward to is a long relaxing shower. You turn on the shower taps, and to your surprise, the water flow is weak, and you are left with nothing but a trickle of hot and cold water. It is hard to ignore a low-pressure hot shower, mainly if you are used to your shower head working with extreme shower pressure. If the other taps in your home are working perfectly fine, what causes low water pressure in your shower can be confusing.
Behind a low-pressure shower lies an issue with your plumbing system. It may be an easy fix or a much larger problem; whatever the cause, you must investigate it quickly, as you risk damaging your house and the rest of the plumbing system.
Ignoring a plumbing problem such as low water pressure can further damage or indicate a leak in the main water line. It may be time to get a professional licensed plumber to find the cause and provide a permanent solution to improve your plumbing.
What causes low water pressure in the shower?
You would have difficulty having a shower that doesn’t provide an adequate water flow for several reasons.
Some older style properties could have a flow restrictor device attached. This is to ensure the water flow doesn’t exceed a certain amount, and it is also used as a water-saving device that is great for the environment and your wallet but not so great in giving you a high-pressure shower experience. Check the head to inspect the condition of the shower-saving device. You may need to replace it.
You can easily take your shower head apart and remove the water-saving device. All you need is a pair of pliers to take the showerhead apart carefully. Removing the flow restrictor opens up the pressure in your shower. You may need to buy a newer low-flow device to see which type will suit your needs.
Over time, your shower head can become clogged with mineral deposits, soap and other gunky material. This can create a barrier between the water and the holes in the showerhead. This is a problem as the pressure in the shower can be compromised.
This can be easily fixed by simply cleaning the heads of the shower. First, start by unscrewing the showerhead and taking apart the different compartments. Inspect the showerhead and remove any debris from the water holes. You can use a toothpick, pin or toothbrush to do this. It is also recommended to soak the head in a bowl of vinegar overnight. The flow of water should increase after a good cleaning.
Water main valve
The water pressure regulator’s job is to keep your home within a safe water pressure range (usually 46-60 psi). Unfortunately, this critical component can fail, allowing the pressure to get excessively low or high. The water pressure regulator is typically located on the water supply line before it enters the home and should only be replaced by a qualified plumber.
If you have issues with the pressure in the shower, it may be a problem with the main water valves and the shower valve. These control the pressure and flow of hot water and cold water supply lines throughout your property.
You can inspect the main valve by locating it near your water meter. Alternatively, you can find the shower valve in the basement, crawl space or access panel behind your shower.
Low hot water pressure could be caused by the valves being shut or not opening all the way. Turning these valves counterclockwise can increase water flow and improve water supply through the pipes.
Check your water pipes for any obstruction or failure in the pipe, such as cracks or rust. Healthy pipes installed correctly can improve water supply flow throughout your home.
Hearing noisy banging inside your wall may indicate leaking pipes, clogged pipes, loose pipes, or need replacement.
How do I fix the low water pressure in my shower head?
Finding why your shower pressure is low is the first step in fixing your low-pressure shower problem.
Clean your shower head
Showerheads can easily remove and clean small mineral deposits and soap and scum. It could take some time and a few tries, but you will increase your shower’s lifespan and strengthen your water pressure.
Remove Flow restrictor
You can also check the flow restrictor by dismantling your shower head and removing or replacing it with a newer model.
By inspecting the shut-off valve, you can ensure that the water supply to your bathroom taps and shower is not restricted. Turn the valve anti-clockwise to open it.
The condition of your water pipes is crucial for strong water pressure. Failing this, hot and cold water pipes can cause low pressure and other major plumbing problems, such as leaks, if not appropriately inspected by a professional plumber.
