Mar 28, 2012 · I've noticed that after using a lot of hot water, if you wait about 10-15 minutes then turn on the hot water there's almost an explosive blast of pressure as the water heater is heating cold water. Letting a faucet drip hot water usually prevents the pressure release valve from going off.
Oct 1, 2024 · If you have too much pressure in your hot water heater, it’s important to take action to reduce the pressure. This can help to prevent the tank from rupturing or exploding, which could lead to serious problems.
- Leaking expansion tank. Water can leak from an expansion tank at one of three places: Pipe fittings. If the pipe fittings at the top of the tank are loose, water may leak out.
- Tank pressure loss. An expansion tank can lose pressure if air leaks from the valve or the diaphragm itself. If the leak comes from the valve, more air can be added to the tank using an air compressor pump or a manual tire pump.
- Tank pressure too high. If the pressure inside the expansion tank is too high, it can be corrected by opening the Schrader valve at the top of the tank.
- Air blockage. An air blockage occurs in an expansion tank when the air inside the tank becomes trapped. The role of an expansion tank is to regulate pressure within your hot water system, but, when an expansion tank fails, the air inside can block water from flowing.

The good thing about an expansion tank is that it helps to regulate air and water pressure in the water system. The tanks are also easy to maintain. However, they are not immune to developing different complications. These issues are common and don’t require a professional to notice. Let’s look at the top problems you might encounter:
The chances of thermal expansion will increase if you add a backflow prevention assembly (check valve) connected to your cold water line. It’s a known fact that water flow is unidirectional, from the supply unit, through the meter, and into the customer tap. Although water is set up to flow in one direction, there are cases where it can reverse its...
Unfortunately, water heater expansion tanks don’t last for a very long time. You might find the tanks getting waterlogged and thus being unable to function effectively. It’s recommended that you at least replace the tanks after 5 to 10 years. However, there are several things that you must do to keep them in good conditions: 1. Watch out for conden...
Even before we focus on why you need expansion tanks on all water heaters, let’s look at the closed plumbing system:
Replacing a bad expansion tank is something that you should do after five to ten years or immediately after you notice a problem. The cost can vary depending on different factors.
Oct 22, 2024 · Key Takeaways: Don’t let low water pressure after installing a water heater dampen your spirits. Follow troubleshooting steps and seek professional help to restore optimal water flow and pressure for a satisfying hot water supply.
Apr 25, 2021 · The normal water pressure in a residential home is 40-70 psi (pound per square inch). While pressure of 40 psi and lower is insufficient to meet your needs, pressure of more than 80 psi will lead to premature failure of appliances, faucet leaks as well as noisy pipes.
