Usage
Designed with the traveling enthusiast in mind, this regulator excels in RVs, travel trailers, and motorhomes where fluctuating water sources can cause damage to plumbing systems. Install it on the main water inlet line to protect sinks, showers, and water heaters from high‑pressure spikes that often occur when connecting to municipal supplies or well pumps. Beyond recreational vehicles, the regulator is equally effective in residential settings, garden irrigation systems, and small‑scale commercial applications where consistent pressure is essential for optimal operation. Its push‑connect fitting simplifies installation—simply push the regulator onto a standard 3/4 in pipe and the secure seal is formed instantly, eliminating the need for additional tools or soldering. Whether you are camping off‑grid, maintaining a backyard sprinkler network, or outfitting a tiny home, the regulator delivers reliable performance in any environment.

FAQ
What size pipe does this regulator fit?
The regulator is designed for standard 3/4 inch pipe connections, which are common in RV water lines, residential plumbing, and irrigation systems.
Can I use this regulator with a well pump?
Yes. The adjustable pressure range (30‑80 psi) accommodates the higher pressures often produced by well pumps, allowing you to set a safe level for downstream fixtures.
How often should I check the pressure gauge?
It is recommended to inspect the gauge during routine maintenance, such as before a long trip or after any major water source change, to ensure the regulator remains set to the desired pressure.
Is professional installation required?
No. The push‑connect design allows most users to install the regulator themselves with minimal tools. Simply push the regulator onto the pipe until it clicks securely.
What warranty does CMI Inc offer?
CMI Inc provides a one‑year limited warranty covering manufacturing defects. Contact their support team for assistance with any warranty claims.
