## Description

Camco's ½-Inch RV Water Heater Backflow Preventer allows water to flow only in one direction— towards your RV’s hot water heater. It does not allow water to pass another way. This helps stop backflow from your RV water heater and into your freshwater system. Features a ½-inch male x female NPT. It is constructed of heavy-duty brass with a stainless spring. Quantity: (1) backflow preventer.

Review: I feel good about getting brass over plastic. - Feels like it’s very solid construction. Easy to install. Used Teflon tape on the installation and have some very slight leakage. I mean very slight. I’m going to get some pipe dope and reassemble and see if that stops it completely from dripping. Happy I went with brass to replace the plastic one that failed.
