Doing this can cause simmer and leakage. Once this starts, it will only get worse. Avoid testing your valve too often. Lifting the test lever too often can allow dirt or other foreign matter to get into the seat, which can cause the valve to leak.
What happens if a valve is not piping?
If it isn’t, the flow will be restricted and the valve won’t relieve as much capacity as it’s supposed to. The outlet piping should not produce any strain due to thermal expansion. As the medium expands, if the piping doesn’t have any give, the valve can warp and leak.
What is the inlet piping?
Inlet piping. The inlet piping should be short and direct. The inlet should never have a smaller diameter than the valve itself. This will constrict the flow of steam, air, or other media. The inlet should never be located near excessive turbulence on the vessel.

How much water is saved by reducing pressure from 100 lbs to 50 lbs?
Reducing the pressure from 100 lbs. to 50 lbs.will result in a savings of approximately 1/3 because 1/3 less water flows at this lower pressure. Remember, there is more "push" behind the water at 100 lbs. than at 50 lbs. and most of this water is wasted. Almost twice as much water flows at 150 lbs. than 50 lbs., most of which is wasted.
