A genuine Triton Black Electric Shower Pressure Relief Valve (PRD 82800450) is the essential safety part that protects your shower’s heating tank from over‑pressure. When water can’t flow out of the shower head, the built‑in burst disc releases the excess pressure, preventing costly damage. This replacement kit comes with a new burst‑disc seal, ready for a quick swap—once the disc blows it cannot be reset.
