Good protection
Reviewed in the United States on September 21, 2025Works as expected, camco is a great brand! It’s easy to install I just leave it on my water hose. It doesn’t leak and isn’t to bulky when connecting hose. The first one I had did freeze and start to leak but it is brass so as long as it doesn’t freeze it should hold up just fine.

Alex Scott1 out of 5 starsThis does not fit onto a standard tap connection as the thread is too course. Suspect it USA thread
Reviewed in the United Kingdom on September 6, 2021Does 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.

ADRIANA5 out of 5 starsExcellent pressure adjustment
Reviewed in Canada on May 26, 2026Tested immediately after receiving this in the mail and it instantly dropped my outdoor bibb pressure to just under 50 psi. Simple, easy to use and effective. I was trying to use rain bird sprinklers and my pressure was 80 psi and it was blowing out the nozzles. This corrected my issue immediately.
