Thanks Luke ,
The pump is something that has been playing on my mind.
I figure the Chiller's flow is rated from 1500lph up to 4000lph .I think I will put a 4000lph . I am too scared to go above that.
I suspect I will lose a fair amount of flow with the distance , I hope that it wont be more of a loss than 2500lph.
also thinking of putting an external pump next to the chiller but I am worried that if it leaks it could ruin me .
Do you think a pump that size placed in the sump will do the job?
