Header tank plumbing

[Julian West]

Dear All,

When plumbing in a header tank, do you take the outlet from the tank to;

tee into the top hose?
tee into the bottom hose? (water pump inlet)
or direct to the water pump?

Just wondering which is favourite. Thanks in advance for any input.

Kind regards
Julian

As close as you can to the water pump inlet is the best. The intent is to provide a positive head of water at the pump inlet

agree, if there is no head (low pressure) at the inlet, the pump will cavitate at higher rpm, introducing air bubbles/steam into the block.

Thank you Gents,

What are your thoughts on plumbing the header tank to the heater return inlet on the water pump ?
