Your pressure gauge shouldn't change a bit while this happens. This is illustrated in the diagram below. The municipal water supply for the house acts as a gigantic expansion tank. In most situations, this water will expand back out through the cold water inlet, all the way back to the water supply coming into the house. This will cause the water to expand significantly until the water heater thermostat is satisfied. You've just replaced the hot water in your water heater with cold water, which will cause your water heater to run for a while. Now stop running water at all of your fixtures and wait. If you have several fixtures open, this should only take about ten to fifteen minutes. Go run a bunch of hot water at your plumbing fixtures until you've exhausted the hot water supply on your water heater, and keep running the water for another few minutes. If the pressure is within the acceptable range, you probably have an intermittent problem with excessive pressure that can be easily re-created. Get a plumber to do that, as they'll need to install an expansion tank at the same time. The solution is to have a pressure regulator installed. If the pressure is over 80 PSI, it should be corrected. You should expect the pressure to be somewhere in the 40 – 80 PSI range with no other water running. If that's not an option, you can also use the hot or cold spigot for a washing machine. The easiest way to do this is to get a gauge with a garden hose thread, connect it to an outside garden hose faucet, and open up the faucet. It doesn’t matter if it’s connected to a hot or cold water pipe, because both will be at the same pressure. Buy a pressure gauge with an extra indicator to show surges, and connect it to the plumbing system. Getting to the bottom of this issue should be quite simple and straightforward. If the pressure in a plumbing system ever exceeds 150 PSI, the TPRV will leak. If a new TPRV is properly installed and it still leaks, you probably have a pressure problem. These valves may look identical, but they’re set to go off at 30 psi, not 150 psi. If a pressure relief valve for a boiler is accidentally installed on a water heater, it will leak like crazy from the start. These numbers will be printed right on the valve, or on a tag attached to the valve. The TPRV on a water heater is set to discharge at 150 PSI or 210° Fahrenheit. When this happens, the fix gets a little bit more involved, and some troubleshooting is in order. If you replace a TPRV and it starts leaking again, it probably means the valve is doing its job it's relieving excess pressure. There are plenty of videos on YouTube showing how to do this, and the whole project probably won't take more than fifteen minutes. These valves cost less than $15 and replacing the valve is a basic job. When a TPRV at a water heater leaks, it's usually a simple fix just replace the valve. This prevents a water heater from exploding or turning into a missile. This valve allows water or steam to escape from the water heater if the temperature or pressure gets too high. Water heaters come equipped with a temperature and pressure relief valve, also known as a TPRV.
