Pressure Relief Device (PRD)
Pressure Relief Device - 82800450
Includes 1 x PRD & burst disc. (fitting instructions included)
Please note that this part fully retrofits the previous part pictured below.

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 below. An instruction leaflet is also supplied with the part.
