Genuine Reliance PREL900960 4.75 Bar Relief Valve for MK2 One Piece Multibloc
The 4.75 bar replacement expansion relief valve for the one piece MK2 multibloc only, with 15mm x 3/4 inch connections. The captive nut may not be supplied.
What it does
Water expands as it heats. An expansion relief valve opens at its set pressure and releases the excess to the tundish, so the system never runs above its design pressure. A relief valve that drips continually is a common sign it needs replacing.
Where it fits
One piece multibloc inlet control valves on unvented hot water cylinders - the replacement expansion relief valve.
Specification
- Pressure setting 4.75 bar
- For one piece MK2 multibloc inlet control valves only
- Connections 15mm x 3/4"
- Captive nut not always included
Installation
G3 qualified installation required (Building Regulations Part G, unvented hot water storage). A genuine Reliance part for a reliable, like-for-like replacement. In stock at Electrical Deals Direct.
