IMPORTANT NOTE: Systems to be installed under constant water pressure should be installed by a licensed plumber with an AS3497 certified pressure reducing valve and back-flow prevention device. We also strongly recommend that a leak detector and shut off device is installed as well. We sell these items in our ebaY store in Accessories. If working with quick fit connectors please see www.splishwater.com.au/Quick-Fits.htm before use. Please let us fix any issues before leaving bad feedback.
