We have a 24RKS White Hawk 2017 Travel trailer. On our second trip out we had something strange happen. Our trailer has two grey tanks. One for the shower/bathroom sink and then the second one for the kitchen sink. The wife took a shower and the water started backing up through the drain. It didn't go outside of the shower base. I didn't realize the one tank being full wouldn't switch over to the second grey tank at that time. She said there was standing water around the outside of the shower stall as she got out and it appeared to be coming from underneath the shower stall. I later pulled the bottom cover off the bottom of the shower expecting to see water underneath the shower compartment. However, I found the floor to be dry and dusty as if no water had ever been there. I checked under the bathroom sink also. I'm not sure where the water came from. Any thoughts?
