probably thinking you couldn't accidentally reverse the flow, while doing an r&r on the system, by forcing you to use two different size hoses.






You couldn't accidentally reverse the flow? If you used the right size hose in the right place.
I think you could, if you used the same size hose as the person before me did. Yes, they seamed to get it right, but using the same size hose, it could be messed up. I think they used the same size hose on all the ports cause it was a lot easier to do so than going back to the store and get the right hose.
