Abstract
A water pressure relief device includes a sample removal port to permit samples of water to be removed from the device. The device has an insert placed in a central chamber disposed generally above the sample removal port. The user inserts an implement such as a syringe into the sample removal port. The tip of the syringe pushes the insert upwards against a pressure relief member, permitting fluid to flow into the base of the device in the vicinity of the sample removal port. The implement then removes or catches the fluid and withdraws the fluid from the pressure relief device.
