Top Hat Grommet (1/2")

If you have purchased or are using your own large tank and do not have access to insert a 1/2″ water barrel tap you can use a 1/2″ Top Hat Grommet. A 19mm hole is drilled at the bottom of the tank and the 1/2″ Top Hat Grommet is inserted into the hole. 1/2″ pipe (hosepipe) is then pushed into the grommet. This will form a water tight connection.
