The pressure gauge on a Hayward S240 sand filter should typically read between 8 to 12 psi when the system is running normally. If the pressure rises significantly above this range, it may indicate that the filter is dirty and needs to be backwashed or cleaned. Conversely, a reading below this range may suggest a problem with the pump or a leak in the system. Regular monitoring of the gauge helps maintain optimal filtration performance.
i think u should i watched the anime and it is awsome ^_^
Yes, it is. You should read it.
The Demigod Files is a good Behind-The- Scenes sort of book if you're looking for more Percy Jackson to read.
You should read his book It came from Ohio, its his biography
You should read books six and seven;)
8 PSI min - 80 PSI max
40 on idle up to 60 while on the move.
800 RPM should yield about 25-40 lbs. of oil pressure on a stock motor.
An air gauge measures pressure relative to the atmospheric pressure, while a water gauge measures pressure relative to its own density. Water is denser than air, so the air gauge reading will be 3 times higher than the water gauge due to the difference in reference points for each gauge.
Need to know which pressure you refer to, fuel, radiator cap, tires, evap, ac, cylinder compression, transmission?
To read an R-134a gauge, first ensure that the gauge is properly connected to the refrigerant system. The gauge typically has two parts: the low-pressure side (blue) and the high-pressure side (red). For the low-pressure side, read the pressure indicated when the system is running; it should be between 25-45 psi for normal operation. For the high-pressure side, readings of 150-250 psi are typical, depending on ambient temperature and system conditions. Always refer to specific manufacturer guidelines for accurate interpretation.
between 35/60 psi.

You need a vacuum gauge and it is reed in inches.
No, the boost gauge should not show boost pressure at idle. At idle, the engine is not under load, and the turbocharger (if equipped) is not producing significant boost. Typically, the gauge should read atmospheric pressure or close to zero during idle, as the engine is taking in air without forced induction. Any positive reading at idle may indicate a malfunction or a vacuum leak in the system.
The number is the pounds per square inch
The cleaner the filter is the lower the initial back pressure is going to be, if you have a valve between the filter and the pool return turn, shut of the flow of water for just a moment. if the impeller is working properly the back pressure gauge should suddenly start to read high. Other reasons for low back pressure may be that the seals inside the unit are not properly settled.
