RentACoop 2 Gallon Chicken Waterer with 4 Auto-Fill Water Cups, 4 Horizontal Nipples, and Custom Adjustable Stand; BPA-Free; Large Capacity Poultry Waterer- Corner Placement

I have this, I use the nipples (NOT the cups) and wash/refill it once a week. I’ve found the cups get dirty & leak. But my flock also drinks from my sheep’s water trough so I’m not sure if it would last a full week otherwise. It would still be a good idea to have your sitter at least glance at it once daily to make sure it isn’t leaking/empty.
