Stepping into your shower with low water pressure is not only miserable, but it’s also a sign that your home may be suffering from a much larger plumbing issue.
Low pressure in a shower can be caused by many different factors, including a clogged shower head, an out-dated mixing valve, a closed valve, a leaky pipe, or even a malfunctioning water heater. Don’t let yourself become consumed with stress because FiveStar Plumbing is here to assist you in narrowing down and pinpointing the exact issue of your shower issues.
How to Fix a Shower with Low Water Pressure
The first thing you need to determine is if the low water pressure is a single, localized issue or if it appears to be more widespread. Here are three questions that can help you determine the answer.
- Is the shower’s hot water and cold water both affected?
- Does the sink faucet in the same bathroom also appear to have low water pressure?
- Are there other areas of the home that are experiencing similar issues?
Once you have the answers to those questions in mind, you can start your investigation to find out exactly what is causing the low water pressure in your shower.
Low-Flow Shower Head
Conserving water is wonderful, however old low-flow showerheads can be quite stingy with your water and make it seem as if the pressure is lacking. Fortunately, making a simple switch from the old showerhead to a newer model is a simple do-it-yourself project!
It’s only so long before mineral deposits begin to accumulate inside the small holes of your showerhead, interrupting or blocking the water flow. Removing the mineral build-up is as simple as placing the entire shower head in a container or bag filled with vinegar and allowing it to sit overnight.
Next, you can use a toothbrush to remove any remaining debris or sediment from the holes of the showerhead.
Worn-Out Mixing Valve
If the settings on your thermostat are set to the correct temperature, the fan motor may keep on running If your shower or bathtub has a single-handed faucet, there may be an internal component called a mixing valve that controls the amount of hot and cold water coming through to the showerhead. It’s not uncommon for that valve to get stuck or worn out over time, causing the water’s temperature and pressure controls to stop working properly. The mixing valve can be a bit difficult to access and replace, so the job would be best performed by a highly-trained plumber.
Faulty Water Pressure Regulator
The job of a water pressure regulator is to maintain a safe water pressure range (typically 46-60 psi) throughout your home. Although, it is important to note that this component can stop working, causing your water pressure to reach excessively high or low levels. The water pressure regulator can be found on the water supply line before it enters the home and should be replaced by a professional plumber, should it break down.
Frozen Evaporator Coils:
If your air conditioner is running, but you somehow still feel warm or hot air blowing from your vents, the evaporator coils may be frozen within the indoor furnace or HVAC unit. These types of issues can limit the evaporator coil’s ability to receive enough heat. This causes the condensation pulled from the air to freeze on the surface of the coils while the system continues to try to cool. This layer of ice on the evaporator coils doesn’t allow the refrigerant to absorb heating energy in the hair.
Frozen evaporator coils can be caused by excess buildup on the coils, lack of air flow from a clogged air filter, blocked room vents, or low refrigerant. Evaporator coils also may develop a heavy layer of ice if the condensate drip pan and drain line below become clogged, causing the system to hold excess moisture.
Your plumbing system is made up of several valves. If any of these valves are partially closed off or blocked, often unintentionally, you may experience lower water pressure in your shower. Go ahead and check to make sure that the main shutoff valve and the inline valves are open all the way.
Water Heater Issue
If the low water pressure in your shower only occurs when using the hot water, there is a chance that the problem may have to do with your water heater. Contact a qualified plumber to assess the unit and determine if it needs to be repaired or replaced.
Corroded or Leaking Pipes
Over time, the water pipes in your home, especially metal ones, get rusty and corroded on the inside. If mineral deposits get trapped inside a water supply pipe, it can cause a disruption in the flow of water to your showerhead or other faucets. Another reason your shower may be experiencing lower water pressure could be caused by a small leak somewhere in your plumbing system. It is extremely important to locate and repair a plumbing leak as soon as possible by contacting a professional plumbing company near you.
