    Customers say

    Customers find the pressure regulator works well for travel trailers and appreciate its brass construction, considering it a reliable investment. The device is easy to use, with one customer noting it's simple for older people to operate. While some customers report no leaks, others mention issues with the swivel joint, and while some say it lasts well, others report it breaking after a month of use. The water pressure aspect receives mixed feedback, with some customers finding it sufficient for garden watering while others say it's too low.

      Works 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.
