Water Pressure Surges After New Water Heater: What You Need to Know

Are you experiencing water pressure surges after installing a new water heater? You're not alone. Many homeowners have reported this issue after replacing their old water heater with a new one. In this article, we'll discuss the possible causes of water pressure surges after a new water heater installation and provide you with some tips on how to resolve the issue.

A week ago, we had our water heater replaced. After the new unit was installed, we were told that there would be some pressure surges due to air in the water lines and that they would last a few hours. However, the pressure surges have continued for several days, and we're starting to get concerned. So, what causes water pressure surges after a new water heater installation?

There are several reasons why you may experience water pressure surges after installing a new water heater. Some of the possible causes include:

Air in the water lines: When a new water heater is installed, air can enter the water lines, causing pressure surges. This is a common issue, especially if the water lines are not properly bled or if the new water heater is not properly connected to the existing plumbing system.
Improper installation: If the new water heater is not installed correctly, it can cause pressure surges. This can happen if the plumber does not follow the manufacturer's instructions or if the installation is not done by a qualified professional.
Clogged or restricted water lines: If the water lines are clogged or restricted, it can cause pressure surges. This can happen if there are mineral deposits or debris in the water lines, or if the water lines are not properly sized for the new water heater.
Leaks in the plumbing system: Leaks in the plumbing system can cause pressure surges. This can happen if there are leaks in the pipes, fittings, or connections, or if the plumbing system is not properly sealed.

Symptoms of Water Pressure Surges

Water pressure surges can cause a range of symptoms, including:

Unpredictable water pressure: Water pressure surges can cause the water pressure to fluctuate, making it difficult to predict when the water will be available.
Leaks in the plumbing system: Leaks in the plumbing system can cause water pressure surges, which can lead to water damage and other problems.
Noisy pipes: Noisy pipes can be a sign of water pressure surges, as the water flowing through the pipes can cause them to vibrate and make noise.
Reduced water flow: Water pressure surges can cause the water flow to be reduced, making it difficult to get enough water for household use.

Resolving water pressure surges after a new water heater installation can be a challenging task, but it's not impossible. Here are some tips on how to resolve the issue:

Check the water lines: Check the water lines for any signs of air, leaks, or restrictions. If you find any issues, have them repaired or replaced by a qualified plumber.
Bleed the water lines: Bleeding the water lines can help to remove any air that may be causing the pressure surges. This can be done by opening the valves on the water lines and allowing the air to escape.
Check the plumbing system: Check the plumbing system for any leaks or restrictions. If you find any issues, have them repaired or replaced by a qualified plumber.
Consider installing a pressure-reducing valve: A pressure-reducing valve can help to regulate the water pressure and prevent pressure surges.
Call a qualified plumber: If you're not sure what's causing the water pressure surges or if you're not comfortable with DIY repairs, call a qualified plumber to help you resolve the issue.

Preventing water pressure surges after a new water heater installation is easier than resolving the issue after it's occurred. Here are some tips on how to prevent water pressure surges:

Hire a qualified plumber: Hire a qualified plumber to install the new water heater and ensure that the plumbing system is properly connected and sealed.
Check the water lines: Check the water lines for any signs of air, leaks, or restrictions before installing the new water heater.
Bleed the water lines: Bleed the water lines before installing the new water heater to remove any air that may be present.
Use a pressure-reducing valve: Consider installing a pressure-reducing valve to regulate the water pressure and prevent pressure surges.
Regularly maintain the plumbing system: Regularly maintain the plumbing system to prevent leaks and restrictions that can cause water pressure surges.

Water pressure surges after a new water heater installation can be a frustrating and costly issue. However, by understanding the possible causes and taking steps to prevent or resolve the issue, you can ensure that your plumbing system runs smoothly and efficiently. Remember to hire a qualified plumber, check the water lines, bleed the water lines, consider installing a pressure-reducing valve, and regularly maintain the plumbing system to prevent water pressure surges after a new water heater installation.
