Typically, a leaking reservoir indicates wear and tear, and once leaks begin, more are likely to follow. For a quick field repair, you can use the Therm-a-Rest Instant Field Repair Kit, also known as a Type A patch. While this can provide a temporary fix, the reservoir will ultimately need to be replaced to ensure long-term reliability.
We have a number of gravity filter reservoirs and hydration reservoirs available online some of these are interchangeable between systems so take a close look at the tech specs and reach out to our team with any questions.
Replacement reservoirs are available on our website:
