General Instruction of Drain Valve Replacement

1) First remove the old drain valve and check the drain valve hole on the transom to make sure the new drain valve matches the hole dimensions.  Then clean up all the dirt from the hole. If there is water in the drain hole, wash it again and leave it dry in the air. Make sure all the condition are good before starting to install the new drain valve.

2) Put the Sikaflex 291i on the drain hole surface about 1mm thickness (5-15g). Wear a glove and use a finger to push the sealant fully coated at the drain hole. Wait 30-60 minutes to let the new sealant coating stay well before putting the new drain valve in.

3) Apply about 5 g of the Sikaflex 291i on the valve and transom contact surface before installation. It helps the valve to get perfect water tight result.

4) Many inflatable boats come with plywood transom with wrong sealant used in the factory. The waterproof coating need to be refinished. Boat's old drain valve may have already caused some water leaking and damage to the transom. This Sikaflex sealant perfectly helps to finish the replacement.
