Learn to replace the valve on LAKEN Jannu and Summit caps in a few simple steps. Keep your bottle leak-free and extend its life with this DIY fix.

Quick answer

To replace the valve on Jannu and Summit caps, remove the old valve from the cap, insert the new valve from the pack, and press it firmly into place. This simple DIY fix restores a leak-proof seal and keeps your bottle working like new.

Why replace the valve yourself?

Over time, the valve in your Jannu or Summit cap can wear out, leading to leaks or a less efficient flow. Replacing it yourself is a quick and cost-effective fix that avoids the need for a new cap or bottle. The replacement valve pack includes two valves, so you have a spare for later.

This DIY repair is safe and straightforward. You don't need special tools or technical skills—just a clean, dry cap and a few minutes of your time. By doing it yourself, you extend the life of your LAKEN bottle and reduce waste.

What to check before you start

Before you begin, make sure the cap is clean and dry. Remove any debris or old sealant from the valve area. Also, confirm that the replacement valve is the correct type for your cap—the pack is specifically designed for Jannu and Summit caps, so it fits perfectly.

If you're replacing the valve because of a persistent leak, inspect the cap for cracks or damage. A damaged cap may need to be replaced entirely, even with a new valve.

Step-by-step valve replacement

Remove the old valve: Hold the cap upside down and gently pull the old valve out of its socket. If it's stuck, use a small flathead screwdriver to pry it out carefully. Check that the socket is clean and free of debris before installing the new valve.
Insert the new valve: Take one of the new valves from the pack and align it with the socket. Press it in firmly until it sits flush with the cap surface. Make sure the valve is fully seated; a loose valve can cause leaks.
Test the cap: Fill the bottle with water, screw the cap on tightly, and turn it upside down to check for leaks. Also, press the valve to ensure it opens and closes smoothly. If you see any leakage, remove the valve and reinstall it, ensuring a snug fit.
