There are 3 under the bed of our 1998 Sea Breeze 1330. The one by itself is a drain for the fresh water tank. The 2 side by side should be marked with a red and a blue crimp for hot and cold. Yes, these are the low point drains for the hot and cold water lines. All 3 will be closed by turning the handles clockwise.
