If you are having trouble with your water pressure when turning on a sink or shower faucet, it might be time to troubleshoot the problem. It might be that there is a very minor issue causing the lack of water pressure, or you may need professional assistance. Here are some common reasons to lack good water pressure.
The Fixtures Have Buildup
Many issues with low water pressure are related to the plumbing fixtures themselves. Since this is an easy thing to check, it is a good way to start troubleshooting the low water pressure issue. For example, if the water pressure in the rest of your home seems to be working just fine, but the pressure in your shower feels low, that shower nozzle is likely the problem. If it looks worn, it may just be time to have a new shower nozzle installed. However, if the nozzle is relatively new and looks to be in good condition, a buildup of mineral deposits might be the culprit. Try removing the shower head and soaking it in hot water and vinegar. Clean the fixture with an old toothbrush or scrub brush to remove buildup, then screw it back on. If you still have a water pressure issue, it is time to call a plumber.
Your Pipes Are Clogged
Having clogged pipes or blocked drains is another common problem associated with low water pressure. You might have already noticed that your drains are running slow. If you have tried to clear the drains with an auger but nothing changed, the problem likely exists a little deeper in the pipes. The pipes might have buildup caused by hair, soap residue, dirt and a variety of different pollutants, depending on how far down the pipes the problem exists. You might also have mineral deposits that have built up in the pipes or corrosion in the piping. With these types of issues, it is typically too far down the plumbing system than what you can handle on your own. You will need to call a plumbing professional to have it repaired.
There is a Water Leak
When you have a water leak somewhere in your plumbing system, that leak could cause other plumbing fixtures to have lower water pressure. Check all plumbing fixtures in your home, including the bathroom and kitchen sinks, toilets, showers and exterior plumbing areas. If you find any pools of water around the fixtures themselves or if you find flooring or walls with obvious signs of water damage, you probably have a leak. This is also something that often requires help from a professional.
