That looks great where did you get itAfter our trip away we decided an external hot tap to fill bucket for washing BBQ, kids and also cold to fill toilet flush tank. The one on the drawbar is a pain under the bed.
I found this and works a treat. Plug hose in with the tap handle with hose and small shower head and you have hot and cold shower. Store the hose in toilet hatch.

Hopefully that check valve will work, looks like it may need pressure to push through it.Put a one way valve so shower doesn't fill up with dish water. Time will tell but testing it it works great.
