I recently built a mud kitchen for my son and one of the must have items was a working faucet. After ruling out some more expensive options, I landed on an affordable and simple solution, a hand pump intended for RV campers.
Caravan Sink Water Hand Pump:
To install the hand pump, I simply drilled a hole to match the base of the pump (32 mm/1.26 inches) and then used the included locknut to secure it into place.
From there, I connected a piece of tubing to the end of the pump and ran it down into an old water jug with a hole drilled into the cap. The modified cap helps to keep the tubing in place and prevents spills.
For the sink, I used cheap dog dishes from Dollar Tree. While they don’t drain, the kids don’t mind and it’s easy enough to dump them once play time is over.
