Toilet installation & technical queries

Who installs the toilet?

The Milu odourless toilets must be installed by a qualified plumber in accordance with AS/NZS 3500. Depending on your installation, an electrician may also be required. It is advisable to check with your plumber on this.

How much does it cost to install?

Installation costs will vary depending on the type of installation (new build vs. renovation or replacing your existing toilet) and your plumbing contractor. For new builds, additional costs will be negligible. There may be a small labour component for your plumber to familiarise themselves with the product. For a renovation, again the additional costs will be negligible.

If you are replacing your existing toilet, we recommend consulting with your plumber and confirming an installation price before proceeding. You should consult with them over the water inlet location and floor waste set-out. There may be additional cost for an electrician to install a power source, if you do not want to use the Battery Pack.

What is the Battery Pack?

The Battery Pack is a compact Lithium Ion rechargeable battery pack, designed to power the Odourless Control Device when a power source isn’t readily available. It sits discreetly alongside your toilet and enables you to update your existing toilet to odourless.

What if I don’t have a power point in my bathroom?

The compact Lithium Ion Rechargeable Battery enables you to have an odourless toilet, even without a power source in your bathroom. This battery will provide up to 18 hours continuous usage (approximately 3-4 weeks typical usage).

If there is ever an issue with the odour control system, will my toilet still work?

Yes, your toilet will always function normally if there is ever any issue with the odour control device. The device has no impact on the fundamental function of the toilet.

How is the odourless toilet turned on and off?

If connected to mains power, Expella recommends the odour control system switches on with the bathroom light, although it can also be shared with the exhaust fan or by a designated switch depending on customer preference. The rechargeable battery has an integrated proximity sensor which automatically turns the fan on and off when someone is in close proximity of the toilet.

How long will the battery last?

The battery will provide up to 18 hours continuous usage (approximately 3-4 weeks typical usage) and is supplied with a charger. To recharge, simply undock the battery pack from the toilet, connect the charger to any general power outlet and plug the charger into the battery. The charge time is approximately 6 hours.

How do I turn off the battery/fan in the middle of the night?

The fan will turn off automatically 2 minutes after vacating the proximity sensing zone. It can also be turned off manually by pressing the Off/Reset button located on the front of the battery.

What is the difference between your concealed cistern to others on the market?

The Milu concealed cistern has undergone significant research and development to optimise the odourless performance. A custom air gasket has been developed to guarantee performance of the odourless system. Apart from this there are no significant differences to the other in-wall cisterns on the market.
