Suppose you are washing dishes and notice low water pressure in one faucet. For instance, you must consider what causes low water pressure in only one faucet while the other is okay.
If the problem is related to the water supply line or you have not opened the water valve correctly, why is the pressure lower in one faucet while the other faucet is completely fine? What’s the matter? What are the possible reasons for lower water pressure in only one faucet?
Here we advise you not to panic, not be overwhelmed by the situation, and not call a plumber. Sometimes many things seem complicated but can be solved easily at home.
So here are the cause and treatments of low water pressure in one faucet. Let the party begin.

Reasons behind low water pressure in one faucet:
When a single faucet appears to be the source of a problem, look for flow restrictions, blocked aerators, dislodged washers, or partially closed supply valves. If there is an aerator on a faucet, remove it, clean it, and reinstall it.
Check the supply valves underneath sink faucets and crank them as far counterclockwise as possible to open them fully.
Close the valves, remove the supply tubes, and ensure no rubber washer inside the connection has fallen loose.
When you face the problem of low water pressure in one faucet, it’s possible that dirt and dust are trapped in that faucet pipeline that needs to be cleaned.
When your hot water faucet is causing hot water problems, your problems are likely caused by hard water.
Pressure is not as desired because of a buildup in the pipes that may obstruct flow into and out of the water heater.
Leaky or corroded pipelines:
Your faucet is very old, and the prolonged use damaged its pipeline. The crack or broken pipeline is leaking water that causes low water pressure.
Your water pipes may become constricted by corrosion and become blocked with scale. Older galvanized iron pipe systems susceptible to corrosion due to the pH level of the water.
Unbalanced PH due to hard water is the most frequent cause of corroded pipelines.
Low pH with acidic water can lead to corrosion, resulting in tiny holes and leaks in your pipes. There is less pressure in the faucets when these tiny pores allow water to escape before reaching your faucet.
High quantities of dissolved oxygen may also cause corrosion in water, sulfate, and iron bacteria; high levels of total dissolved solids (TDS), and silt in the water can wear down pipelines.
The faucet structure contains rubber bands and discs. So when the minerals or bacterias accumulate and start depositing on the rubber bands and gaskets. They become mushy, and they clog the water passageway of your faucet. Ultimately lowering the water pressure in one faucet.
It is crucial to check the faucet and fixture itself and the connections, as problems with seals and connections might affect the water pressure flowing out of the faucet.
In addition, hard water from a municipality or a private well can lead to buildup that clogs faucets and fixtures and, in rare cases, even causes them to break completely.
Your water’s hard minerals, such as calcium and magnesium, can build up and cause issues with your fixtures and faucets.
Locked and leaky valves:
When the water valves are leaky or blocked for any reason, your faucet receives low water pressure or stops working. The problem can happen in the old valve damaged by continuous use.
Valve problems may cause low water pressure provided by local municipalities. You should call the municipal community for your lower water pressure.
Two crucial valves are in city homes linked to a municipal water supply. One is located at street level, outside the home, at the water meter, and the other is the main water shut-off valve.
You can notice a variation in the water pressure if one or both of these valves is partially closed.
Although valve problems are rare, it’s recommended to call your local public works agency to have it checked out if there is a rapid shift in pressure.
How to solve faucet-related problems:
It is simple to examine an exterior pipe when there is a pipe issue. The majority of faults, however, are caused by underground or wall-mounted pipes. As a result, you should ask a qualified repairman to handle it. Before repairing it, they will inspect it using specialist equipment to find the leak.
If the valve is partially or entirely closed, you should open it by following the “open” indication on the valve. Change the valve with a new one if it is leaking.
Use a vinegar solution and a toothbrush to clean out a mineral or debris-clogged faucet. Use a brush to clean the faucet after allowing it to soak in vinegar for 10 to 30 seconds.
If a shower is involved, use a vinegar solution and a toothbrush to clean out a mineral or debris-clogged faucet. Use a brush to clean the faucet after allowing it to soak in vinegar for 10 to 30 seconds. You may clean a shower using interdental brushes if it has little holes. Replace the rubber band with a new one if stretching caused the hose to become damaged.
- What causes low water pressure in only one faucet?
There may be an issue with the fixture if you have low water pressure in one faucet.
Furthermore, a clogged aerator or clogged cartridge is the most typical reason for low water pressure in one faucet.
- How to fix low water pressure in one faucet?
You can solve the lower water pressure problem by removing the aerator with the help of pliers and checking the mineral deposits inside it. To get rid of dirt or debris, rinse the aerator in hot water and scrape it with a brush. If this cannot solve the problem, then replace the aerator.
- Why is my cold water pressure lower than my hot water pressure?
Any constraint in the dispersion of cold water flow can cause low water pressure. Perhaps other potential causes include partially closed valves, too small pipes, partially blocked pipes, and excessive use of faucets.
- Why does my bathroom faucet have low water pressure?
Blocked aerators and cartridges are two of the most typical reasons a sink has poor water pressure. The cartridge, located beneath the sink handle, permits you to initiate and stop the water flow. So the clogging in cartridges will cause low water pressure in your bathroom faucets.
- What causes low water pressure in the whole house?
Low water pressure in the home may seem to be caused by leaks and blocked drains. It just makes sense that your water pressure would be decreased if your pipes were dripping large volumes of water.
When you are facing the problem of low water pressure in one faucet, then you don’t need to take professional assistance. You can resolve the issue by shutting off the valves, checking faucet aerators, and cleaning the clogged cartridges.
If you are facing the issue of lower water pressure than your home, then it’s time to take professional assistance.
