Use Module Accessory Packs to upgrade your system to AQUAvalve5 with 9mm and 16-9mm pipe and fittings. An AQUAvalve5 Module Accessory Pack will fit into your existing module trays perfectly. It includes all the fittings you need to connect to 16mm pipe – even 16-9mm cross and tee connectors. If connecting directly to the reservoir using 9mm pipe you may also require the new 9mm Top Hat Grommet and 9mm Golf Filter or, if your reservoir has a 16mm outlet, the new 16-9mm click-fit adapter and filter.
