If the plumbing system in your home is old, it’s possible that you will experience low water pressure from time to time. In modern homes, water demand has increased due to the use of garbage disposal, water filter, and other appliances.
Whether you have a brand-new home or an old one, you may face low water pressure in a single faucet. What causes low water pressure in only one faucet? How to increase the water pressure of the faucet? All answers are explained in this guide. Fortunately, there are simple solutions that you can use to increase the water pressure.
What Causes Low Water Pressure In Only One Faucet?
Low water pressure in only one faucet is quite frustrating. Due to low water pressure, you don’t get spray as strong as you were getting. So, the faucet takes more time to fill pots and the dishwasher takes more time to run its cycle.
When water pressure is low only in one faucet, you only need to remedy that faucet or its pipe fitting.
The most likely reason for low water pressure in only a single faucet is a blockage in the line that is connected to that particular faucet. The pipeline gets blocked due to the build-up of hard water or debris. With time, the number of build-up increases and it blocks the way of the water.
Also, a shut-off valve may cause the issue of low water pressure in a single fixture only. In most kitchens, fixtures have a shut-off valve under the sink. It remains generally open. If it is not fully open, the water flow will not remain the same. The flow will be reduced and cause low water pressure in that faucet.
Another cause of low water pressure is a clogged aerator. If the aerator of any faucet is clogged due to build-up or debris, it also slows down the water pressure. You need to clean the aerator to increase the water flow.
How To Fix Low Water Pressure In One Faucet Only?
You go to the kitchen to clean dishes but what you get is only minimal water pressure. You check other faucets in the house and find that only a single tap has a low water pressure issue and others are working fine.
But don’t worry here are some quick fixes which will increase the water pressure of any faucet.
- First, you need to turn on the shut-off valve of the faucet, if it is in the off position. Go underneath the sink. Use a flashlight for better visibility. Turn the valve into the on position and if it is stuck, use a wrench to turn it. If the valve is already in on position, move to the next solution.
- Check the aerator and if it is clogged, you need to clean it. Remove the aerator by using the aerator key. Take vinegar into a bowl and leave the aerator in it for a few hours. Now remove it from the vinegar and clean it with water. If some holes are still clogged, use a toothpick to open them and reattach the aerator to the tap.
- If an aerator is no problem, then remove the connected pipes of the faucet. For this, first, turn off the shut-off valve. Now remove pipelines and fit them with water, if there is no water coming out from the other side of the pipelines, it means they are clogged. To repair clogged pipelines, you need to call a plumber.
- If all things are ok and still you are getting low water pressure, it is time to replace the faucet. Your faucet is not in the right condition to produce normal water pressure.
Why Is My Cold Water Pressure Lower Than My Hot?
This is generally not a common issue. People face low hot water pressure but cold is normal due to problems with the water heater.
Whether low cold water pressure has built slowly or over time, it is not good. It is a clear sign that something is not right with the cold side plumbing of the faucet.
Every kitchen tap has a hot and cold water supply. There would be a different shut-off valve under the sink for hot and cold water supply. First, you should check the cold water supply valve. Maybe any other family member has closed it due to any plumbing work. Turn it on. Another possible cause is a clogged cold-water pipeline.
