Decreased Hot Water Pressure? Here’s What To Do
Low hot water pressure can turn even the simplest tasks into frustrating experiences. Whether you're trying to take a relaxing shower or wash the dishes, weak water flow can be a real nuisance.
The good news is, decreased hot water pressure is a common problem with several possible causes, most of which are easy to fix.
From sediment buildup in your water heater to clogged pipes or a faulty pressure regulator, there are plenty of reasons why your hot water might not be flowing as strongly as it should.
In this blog, we’ll help you identify the root of the problem and guide you through some simple steps to get your hot water pressure back to normal.
So, if you’re tired of dealing with that weak stream of hot water, read on to discover what you can do to restore your home’s water pressure and enjoy a better flow today.
Common Causes of Decreased Pressure
Experiencing low hot water pressure can be frustrating, but understanding the common causes can help you pinpoint the problem faster.
Here are four of the most likely reasons:
- Sediment buildup in the water heater: Over time, minerals like calcium and magnesium can accumulate at the bottom of your water heater. This sediment buildup restricts the flow of water, leading to reduced pressure. Flushing your water heater regularly can help prevent this issue.
- Corroded or blocked pipes: If you have an older home, your pipes may be corroded or clogged with debris. This restricts water flow and decreases pressure, especially in the hot water lines. In severe cases, you might need to replace the affected pipes.
- Faulty pressure regulator: A pressure regulator helps maintain consistent water pressure in your home. If it’s malfunctioning, you may experience inconsistent or low pressure, especially in your hot water.
- Leaky pipes or water heater: Even small leaks can have a big impact on water pressure. If you suspect a leak, check for damp spots around the water heater or along your pipes. Fixing leaks can restore your water pressure.
Identifying these common issues can help you decide on the next steps to fix your hot water pressure.
DIY Solutions for Low Hot Water Pressure
If your hot water pressure is lower than usual, there are a few simple fixes you can try before calling in a professional.
Here are some DIY solutions that might help:
- Flush your water heater: Over time, sediment builds up in your water heater, which can block the flow of water. Draining and flushing your water heater can clear out these mineral deposits and restore pressure. Check your owner’s manual for instructions, but generally, this involves turning off the power, connecting a hose to the drain valve, and flushing the tank with cold water.
- Clean or replace tap aerators: Tap aerators are small screens that can get clogged with debris and minerals, reducing water flow. Unscrew the aerator from your tap, rinse it, and soak it in vinegar to remove any buildup. If it’s too clogged, you might need to replace it.
- Check the water pressure regulator: Your home’s water pressure regulator may be set too low or could be faulty. You can adjust it by loosening the locknut and turning the screw to increase pressure. However, if you’re unsure, it’s best to leave this to a professional.
These easy DIY steps could save you time and money while restoring your hot water pressure.
When to Call a Professional Plumber
Sometimes, no matter how much troubleshooting you do, the problem of low hot water pressure can persist. That’s when it’s time to call in a professional plumber. While there are a few DIY fixes you can try, like flushing the water heater or cleaning the tap aerators, there are certain signs that indicate a bigger issue is at play.
If your entire house is experiencing low hot water pressure, the problem might be with your pipes. Corrosion, leaks or blockages deep within the plumbing system require professional expertise to diagnose and fix.
A plumber can perform a thorough inspection to pinpoint the issue and recommend the right solution, whether it’s repairing or replacing the pipes.
Another sign that you need a professional is if you notice fluctuating water pressure or hot water that takes too long to heat up. These issues could indicate a failing water heater or a malfunctioning pressure regulator, both of which need expert attention.
Ultimately, calling a plumber ensures that your hot water pressure problem is resolved quickly and correctly, saving you from further frustration and potential damage. If DIY solutions aren’t cutting it, don’t hesitate to bring in a fully qualified plumber.
Preventing Future Decreases in Pressure
Once you’ve resolved your hot water pressure issues, it’s a good idea to take some steps to prevent it from happening again. Here are a few tips to keep your hot water pressure strong:
- Regular water heater maintenance: One of the easiest ways to avoid pressure problems is by flushing your water heater annually. This removes any sediment buildup that can block the flow of water. Regular maintenance also helps extend the life of your water heater, saving you from costly repairs or replacements.
- Check for leaks periodically: Even small leaks can reduce water pressure over time. Make it a habit to check for signs of leaks around your water heater and pipes. Catching leaks early not only prevents pressure loss but also saves water and prevents potential damage.
- Upgrade old pipes: If your home has older plumbing, especially if the pipes are galvanised steel, corrosion could become a recurring problem. Upgrading to modern materials like copper or PEX can improve water flow and prevent future drops in pressure.
- Inspect your pressure regulator: Having your pressure regulator inspected periodically ensures that it’s working correctly. A malfunctioning regulator can cause sudden changes in water pressure, so it’s good to keep an eye on it.
Taking these preventative measures will help ensure consistent water pressure for the long haul.
