Pressure regulators are adapters that control the flow of water into a plumbing system. A travel trailer will need water inputs when staying in RV parks, and each park can have a different level of water pressure.
Travel trailer plumbing systems should have a pressure regulator that has a limit of 45 pounds per square inch (psi). This will ensure the integrity of the plastic plumbing throughout the trailer.
Another concern with water flowing into the a travel trailer's plumbing is the quality of the water. Many owners install a water filter, normally placed before the main trailer water connection, to ensure that the water that enters the trailer is clear and clean for necessities such as dish washing and showering.
