Top or Bottom Water Outlet: How to Plan Kitchen Pipes

Two Outlet Types

Bottom outlet: connections under the sink cabinet, the mainstream for under-sink heaters. Top outlet: wall-mounted points above the counter, common in retrofits.

Impact on Heaters

• Bottom: widest model choice, minimal pipe loss.
• Top: only some wall-mount models; keep hoses short.

Three Renovation Tips

1. Reserve a tee position on the cold-water line.
2. Mount the socket on the cabinet side panel, 15cm+ from water joints.
3. Insulate any exposed hot pipe.
