Separett Ejectortank

Function

The Ejector Tank uses water pressure to draw urine from the tank and mix it with water. For use on plants, the minimum required water pressure is 29 psi (2 bar). We recommend at least 36 psi (2.5 bar) to achieve an approximate urine-to-water ratio of 1:10.

The mixing ratio varies with water pressure:

• 14.5 psi (1 bar): approximately 1:4—for moistening compost only, not lawns or plants.
• 29 psi (2 bar): approximately 1:8—for cautious fertilization of established lawns and nutrient-demanding plants growing in the ground.
• 43.5 psi (3 bar): approximately 1:12—for established lawns, perennials, and vegetable crops growing in the ground that need nitrogen.

These values are approximate. Hose length, elevation differences, and available water flow affect both emptying and dilution. Higher pressure is required when watering uphill.

Use

Connect a ½-inch garden hose to the tank’s water inlet using the supplied connector. Depending on the market, the tank has either a quick-connect fitting or a standard garden hose connector.

Fully uncoil the included ¾-inch discharge hose and straighten any kinks. Position the spray nozzle where you want to distribute the mixture, then turn on the water supply. Check that the mixture flows from the nozzle and that the liquid level in the tank falls. If the tank fills instead of emptying, turn off the water and check the installation.

Distribute the mixture evenly over moist soil during active growth, avoiding leaves and edible plant parts. Follow local requirements for using urine as fertilizer.

A slurping sound normally indicates that the tank is empty. Flush the ejector unit as described below, then turn off the water supply.

Position the Ejector Tank so that the urine hose slopes continuously downward from the toilet to the tank. Avoid low points where urine can collect. When connected to a ventilated Separett toilet, such as the Villa or Tiny, the toilet’s ventilation draws air from the tank through the urine hose. The connection at the tank lid therefore does not need to be airtight.

The tank can be partially buried, with the lid remaining above ground and accessible. Place it on a stable base and allow access to the connections and level indicator. It does not need to be moved for normal emptying or cleaning.

Keep the discharge nozzle as close to tank level as practical. Watering uphill requires additional water pressure: approximately 1.45 psi per 3.3 feet of elevation gain (0.1 bar per vertical meter). Consider both the height difference and discharge hose length when choosing the tank’s location.
