Old style PRD 82800450


A Pressure Relief Device (PRD) is a safety feature installed in Electric Showers. If heated water fails to escape through the shower head (due to a blockage such as a kinked hose or blocked shower head), the PRD will blow, thereby allowing the water to escape through an outlet pipe before it causes damage to the heating tank. A PRD cannot be reset once it bursts and must be replaced.


How to fit

See how to change a PRD in our short video in the gallery. An instruction leaflet is also supplied with the part.
