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.

No good in Britain
This device doesn't fit British taps so is no good for caravan use

Safe pressure for the caravan
Fit this to the supply tap when using direct water connection to the caravan, prevents high pressure from blowing pipe connections inside the caravan.

Replaced a less expensive regulator which had failed with this one. It worked perfectly right out of the box. The pressure gauge on the cheaper one had previously failed, as leaking water had invaded the gauge and ruined it. After replacing the gauge, the regulator itself stopped regulating. We shall see if the gauge on this Camco regulator stands up to long use. Meanwhile, this new Camco regulator itself seems better made and is slightly more compact.

Use on a soaker hose to keep water pressure down. Works really well. Recommended.

This Camco brass water pressure regulator with gauge is an absolute must-have for RV owners. The built-in gauge lets you see exactly what pressure you're dealing with at each campsite, which is invaluable. Some campgrounds have dangerously high water pressure that can damage RV plumbing, and this regulator protects against that. The all-brass construction is quality—no cheap plastic components that'll crack or fail. It feels substantial and well-made. The threads are clean and seal properly without leaks. The gauge is easy to read and appears to be accurate based on comparing it to other pressure measurements. The regulator does its job perfectly, limiting incoming pressure to safe levels for RV systems. I've hooked up to campground water supplies ranging from weak to excessively high pressure, and this regulator handles it all. No more worrying about blown fittings or damaged water lines. Installation is simple—just thread it onto the campground spigot before connecting your water hose. The compact size doesn't add much bulk to your setup. Easy to store when not in use. This inexpensive part can save you from expensive plumbing repairs. Every RV owner should have one of these in their setup.

Excellent, reduces the pressure as needed and expected. I have a fancier regulator with the pressure guage on it and bought this as a backup. Always need a spare in case you forget the one on the line as you're packing up. Worked just as expeceted when I tried it out.
