ABSTRACT:
A device to protect garden hoses and other fluid conduits from wear and bursting caused by pressure build-up due to heat generation particularly from the sun's rays. The device can be attached between the house spigot and hose or at the end of a hose between the hose and spray attachment. The device comprises a housing with a threaded inlet end for attachment to a hose or spigot, a central chamber containing a thermostat in a valve moveably mounted on a spring, which together are adapted to open water release holes at the outlet port end when water temperatures reach a predetermined level and close when the water temperature decreases to a second predetermined level. Sufficient openings in the device, allow full flow of fluid through the inlet port, the chamber and the outlet port and attachment, but still provides protection against pressure build-up when the hose is not in use.
