Bottle Top Waterers - Gardening Naturally - BT001

They are designed for a 27.5mm internal cap diameter. While many squash bottles fit, standard narrow-mouth water bottles may not be compatible.

Yes, but ensure you clean the cap thoroughly after every use to prevent chemical crystallization inside the holes.

Gently poke a needle through the blocked hole or soak the cap in a mild vinegar solution to dissolve mineral buildup.

It is recommended to hand wash them with warm, soapy water to preserve the integrity of the plastic threads.

Check that the cap is screwed on level. Cross-threading is a common cause of leaks in plastic bottle attachments.

Ensure the bottle is a standard 27.5mm size and verify there is no damage to the bottle threads.

Rinse the cap under warm water to dislodge any debris or mineral deposits that may have entered the holes.

Loosen the cap slightly or poke a tiny hole near the top of the bottle to allow air to enter and prevent a vacuum seal.
