Can a Bad Water Heater Cause Pressure Loss?

As a homeowner, you've probably experienced a situation wherein you turn on a hot water faucet and only a trickle of water comes out; or turn on the shower, and instead of a strong and steady flow, the shower head spits out a weak drizzle.

These situations are not just annoying; they can also make it impossible to carry out daily household tasks such as cleaning dishes, washing clothes, and showering.

Low water pressure in the hot water outlets in your house could be an indication of a problem with your water heater.

When hot water leaves your water heater, it should flow at the same pressure as cold water enters the appliance. In other words, hot and cold water should flow at equal pressures. When your hot water pressure is lower than usual, you could be dealing with a faulty water heater.

Low hot water pressure should be addressed quickly to avoid inconveniences and further plumbing problems. Mostly, this problem is caused by either faulty water heater components or issues to do with the water supply lines. Ignoring low hot water pressure could cost you a lot of money down the line in costly repairs or replacements.

If you’re experiencing this problem in your house, you can rely on our affordable plumbers at Beall Contracting to fix the problem. At Beall Contracting, we are always ready to help you with all of your water heater issues and plumbing needs.

Let’s look at the possible reasons for low hot water pressure and what you can do to prevent the problem from occurring.

Sediment Build-Up

The minerals and sediments present in water may slowly build up in the outlet pipe leading from the tank, thereby restricting the amount of water that can pass through the pipe and to the rest of the hot water outlets in your house. You’re more likely to experience this problem if you have hard water in your home.

Low hot water pressure can also be caused by the accumulation of sediments in the hot water tank. For tankless water heaters, scale buildup can cause pressure loss.

Sediment build-up may also reduce the efficiency of your water heater and increase your heating costs. To avoid sediment build-up in your tank, you should flush the appliance regularly.

The Shutoff Valve is Partially Closed

In some cases, the shutoff valve that regulates the flow of water may not be open all the way, and this may restrict the flow of water from your water heater.

The Pressure Regulator Is Failing

If your hot water supply lines have a pressure regulator, the device may malfunction due to regular use, resulting in reduced water pressure. In some cases, the pressure regulator may not be configured correctly, thereby causing pressure loss.

Bottom Line

A bad water heater can cause pressure loss but there are other plumbing issues that can this problem.
