Triflo spa bath pump air bleed valve

Triflo spa bath air bleed valve - replacement part.

If the pump is installed too high, this air bleed may require activation to allow trapped air to escape, and the pump to run.

To activate, it needs to have the inner 'blank' drilled out and a tube attached and run vertically upwards 500mm to contain any water that may spurt out on pump start up.
Do not activate the airbleed unless necessary. A correctly installed pump / correctly plumbed spa bath will not require activation.
