Doing offerings to the element on its associated power days is a good way of rekindling your connection.
For the element of water, keep an earthen bowl of purified rain water or filtered tap water with a pinch of sea salt on display in your altar (or elsewhere in your home). Meditate before it frequently, especially on Mondays and Fridays - Mondays are associated with the Moon, and Fridays with Venus, both of which are connected to water.
Aquamarine, coral, opal and pearl are all excellent gemstones for invoking water. Display these in or around the bowl. Onycha and myrrh are also great for channeling water; light an incense or burn either with a charcoal brick and pass the bowl through the smoke.
Good luck, and blessed be.
