Description

Top Hat Grommets provide a water tight connection using 9mm pipe with the 30 & 47 L plastic reservoirs.

The Top Hat Grommet is positioned at the bottom of the reservoir. All AutoPot 30 & 47 L plastic reservoirs are now supplied drilled and with 9mm Top Hat Grommets.

If fitting a 9mm grommet (for AQUAvalve5) to an existing/non-AutoPot plastic reservoir drill out to 12.5mm diameter.

The grommet is then inserted into the hole and a length of 9mm pipe is then pushed through the grommet. Push the pipe all the way through the grommet so that you can see the tube protruding inside the reservoir.
