Sink

See Sink/Stove Combo

Faucet

Marine Cold Water Folding Kitchen Faucet [ amazon ]

This faucet's shutoff is in the UP position which causes the handle to hit the glass cover. The handle position was adjusted to remedy this issue.

To connect the faucet to our 3/8" braided line, we use 1/2" Pex x 1/2" Female NPT Swivel Adapter [ amazon ]

Pump

Switch

A rocker switch with a blue LED  was used to activate the pump. [ amazon ]

A switch with an LED was used to help identify when the pump's power was left on.

Quick Disconnect

A quick disconnect with shutoff was used to help with refilling the water jug. Without it, water would leak all over when removing the tub from the jug.

I used a disconnect I had kicking around but they can be purchased online.
