Marathon SP623335 T-fitting Vacuum Relief Valve

In order to assure proper warranty coverage, a vacuum relief valve must be installed on the cold water inlet.It can be installed in either the vertical or horizontal position.Without this valve a break in the main supply line can create a vacuum inside the water heater irreparably damaging the inner tank.

This replacement t-valve is the complete assembly, no separate brass t-valve required.For a vacuum relief valve that fits into a t-fitting, please see part number SP623336.
