The Camco 40055 Brass Water Pressure Regulator is by its nature a flow restriction device as most pressure regulators work in this manner.
Any water pressure regulator may be subject to failure. Failures are normally caused by a manufacturing or mechanical defect or physical damage.
The Camco model 40055 has a preset water pressure (between 40-50 PSI) on the outflow side. This protects the camper’s plumbing from high water pressure that may be present at the supply and which would cause damage to the trailer’s plumbing system if left unregulated.
This water pressure regulator is designed to ensure a safe pressure on the inside of the camper even when there is no flow but this device does not equalize to the higher pressure when no flow is present.
Camco and other manufacturers make other water pressure regulators that are adjustable in nature and have a pressure gauge built onto the body of the regulator. Both fixed and adjustable pressure regulators perform the same function in broadly the same manner but one is adjustable and can have a visual reference to the reduced water pressure.
Personal preference may dictate which one any particular customer may ultimately find preferable, but both do safely perform the pressure regulation function.
In an effort to reinsure confidence of the 40055, we selected a random sample of three pressure regulators from inventory and subjected them to testing.
The test method employed was a water pressure test with a supply pressure of 100 PSI produced buy our water pressure testing equipment. (All campers are subjected to an 80 PSI pressure test of the water lines as mandated in the RVIA Testing Regulations). A water pressure gauge was attached to the low pressure side of the regulator with water in the valve, 100 PSI of water pressure was applied at the inlet, the outlet recorded a pressure of 44 PSI, +or- 2 PSI on all three valves tested. This method of testing simulated a zero flow and did not result in an equalization of pressure to the higher inlet pressure. Furthermore when the 100PSI was disconnected from the inlet, the valve maintained the 44 PSI on the low pressure side until the pressure was relieved by removing the gauge (similar to opening a faucet).
The observed testing appears to support the premise that the pressure regulator Camco 40055:
Regulates incoming high water pressure and regulates it down to the stated safe pressure range of the regulator (40-50 PSI).
There is no equalization of pressure between the two sides of the regulator under water present but no flow conditions.
When high pressure source is removed, the lower pressure is maintained on the low pressure side of the valve until relieved by such things as the operation of a faucet.
Our tests indicate that the Camco 40055 water pressure regulator performs its required function of reducing water pressure. As previously stated, this valve does not give the ability to adjust water pressure or give a visual representation of pressure, which may be the preference for some and a matter of personal choice.
