A complete 25mm grey-water plumbing kit for connecting a compact campervan sink to a removable waste tank.

Waste plumbing kit includes

• 1 × 25mm 90-degree threaded elbow.
• 2 × 25mm double-male BSP hex nipples.
• 1 × 25mm ball-valve shut-off.
• 1 × 25mm male Camlock fitting.
• 1 × 25mm female Camlock hose-tail coupler.
• 1 × 25mm Camlock dust cap - for use when emptying or travelling.
• 1 × 1 metre length of 25mm wastewater hose.
  

Choose the plumbing-only kit, or add the compatible stainless sink and 25mm 90-degree sink waste outlet with plug.

Installation

The main tank outlet commonly needs a hole of about 32mm. Measure the supplied fitting before drilling with a hole saw or step drill. Use compatible wastewater sealant and PTFE tape on suitable threaded joints, then leak-test before use.

The exterior waste-tank vent and fresh-water breather are separate products. Final self-containment compliance depends on the complete vehicle installation and inspection.
