The T4 Fountain features 4 holes. It is a bottom fed design with an extra thick 3/16" disc for heat retention

It has the ability to hold 1 14mm valve marbles.  I DO NOT recommend heating borosilicate marbles inside the quartz. They should be inserted after heating.

Drain Valves made by us are sold separately.

Inner Diameter of top is 15mm with a 2.5mm wall thickness.
