great. Thanks for all your help Brian

One more quick question Brian:

I'm logistically trying to figure out the best way to organize the cabinet with the new spa pack.

I have a suction system; pump pulls water thru the filter/drain, thru the heater then pumps it out to the jets.

I know it is critical to connect the filter/drain PVC line correctly to the side of the pump, and then the spa pack line to the top of the pump, but does it matter which side the water exits/enters the spa pack? In other words, could the distribution (post heater) be on the left or right, and vice versa for the line coming from the pump (pre-heat)?

Thanks again !

It'll work in either direction... No issues, no problems.

great. Thanks. I'll call if I have any issues with the install.
