Hi,
I’m trying to replace the Drain hose on this unit. I recently ordered [AP3178188](http://www.appliancepartspros.com/Appliance-Parts/whirlpool-hose--drain-item-number-ap4399659.aspx"AP4399659Hose, drain]Hose, drain[/URL] Part Number: , but before I removed the existing hose I noticed the elbow attachment at the tub end of the hose. Should I have ordered - Check valve included. Part Number: [URL="http://www.appliancepartspros.com/Appliance-Parts/whirlpool-hose--drain-item-number-ap3178188.aspx)?? Is the elbow connector the check valve? And if so, is the check valve rigidly attached to the hose? I guess what I’m asking is can the hose without the check valve be attached to the existing check valve, or do I exchange the hose without the valve for the one with it and replace hose and valve?
