High Pressure Hose Problem SOLVED
This water pressure regulator worked perfectly on my back yard hose bib. It significantly reduced the incoming pressure coming to my zeroG expandable hose and no doubt increased the useful life of the hose. My high pressure problem is solved.

Not for use on Maytag / Whirlpool washer hoses
DO NOT buy these to use on Maytag / Whirlpool washer hoses. They work too well... they knock the water pressure down so low that the sensor in the washer can't tell there's enough water pressure to start the cycle. It sits there in "Sensing" mode forever and thinks there's no water.

It’s a Water Pressure Regulator
I use this on my Class C RV. It works as intended. It’s a great quality product and seems very well made.

This does not fit onto a standard tap connection as the thread is too course. Suspect it USA thread
Does not fit the standard British tap connection found on camp sites. Also threaded push on connectors do not fit on the male end either. Found out too late to return the item. Suspect it’s for America not UK market.

Peace of Mind for My RV Plumbing!
I use this Camco Brass Water Pressure Regulator on my RV, and it’s been a total lifesaver. Before, I worried about campground hookups having water pressure that was too high, but this keeps it steady and safe between 40–50 PSI. My hoses, kitchen sink, and appliances are all protected, and I don’t have to stress about leaks or damage. It’s solid brass, feels very durable, and I love that it’s drinking-water safe. Easy to attach and works exactly as promised—one of those small investments that saves you big headaches down the road. Highly recommend for any RV owner!

No se le puede enroscar nada
Cualquier rosca que intento ponerle por abajo ya sea de plastico o laton no pasa de la primera vuelta y se sale el agua un desastre. Esa rosca o esta mal hecha o es un tipo de rosca diferente.
