"The normal range of water pressure in a residential application is between 40 psi and 80 psi. There is no specific rule about how much pressure is best for your house, since everyone's needs are different. However, anything below 40 psi will likely lead to poor performance of devices that use water. Anything higher than 80 psi could lead to damage, such as blown sprinkler heads or ruptured pipes. Check your pressure regularly by attaching a pressure gauge to an outdoor faucet and turning on the water."
When working on a water plant for a manufactured home/camper park - the water pressure was set at 65 PSI.
Campgrounds with private water sources may be different.
