A fire hydrant should be opened fully to ensure maximum water flow and pressure during firefighting operations. Opening it partially may restrict the flow and hinder firefighting efforts.
Depending in the hydrant suction, pump pressure should be about 80-100 psi
A pressure switch can be normally open or normally closed. It depends on how it was made. The NO/NC should be marked somewhere on the switch. A pressure switch can be normally open or normally closed. It depends on how it was made. The NO/NC should be marked somewhere on the switch.
how far should park ferom a fire hydrant in new brunswick
Oil pressure varies but should normally be around 40psi
There is no reason to dump the water from a fire hydrant. The only reason a fire hydrant should ever be opened is if there is a fire or people are dieing from lack of water on a severly hot day.
The water pressure depends on the residual air pressure in the tank. Normally it should be between 30 -50-psi. Tank air pressure is important, it should be about 27-29 when water is nearly empty.

Normally between 40 and 80 psi, but mine runs about 90....
If a driver hits a fire hydrant on private property, then he or she is to blame. The hydrant is a stationary object that the driver should have been able to easily avoid. It is likely that, even with insurance, the driver will have to pay for any damages.

Depends on what vehicle you are driving. The recommended pressure is listed in your owners manual and normally on the drivers door post.
