I'm currently researching the drainage process for the J470. I see there is a quick drain and a hose attachment. I didn't receive separate tubing for the Quick Drain. Was that supposed to come with the tub?
Is there a preferred way to drain to ensure the tubing is fully purged? I saw other folks with other methods involving a shop vac, utility pumps, and sump pumps, but wanted to check here before I go out of my way on another investment.
