Sustee Water Meter - Refills 2 Pack (3 sizes)

$15.50 NZD

Pick your size above

Small, Medium and Large available. A single pack comes with 2 core refills included, giving you at least a year's supply (each core lasts 6 to 9 months).

How long does a Sustee refill last?

One core will last about 6 months on average. Your Sustee comes with the housing (which is reusable) and one core already inserted in the housing, ready to use. When it's time for a new core, get them here. Just pick Small, Medium or Large to match your size of Sustee.

How do I know when I need a new refill?

If your Sustee shows no reaction or colour changing at all but is not clogged or blocked, and you've had to about 6 months or longer, it's likely time for a refill. 

Are the core refills recyclable?

Yes! Keep the housing. It's reusable. Don't throw it away! The core inside is made of natural fibres which can be broken down by microorganisms.


How do I change the core?

Take your Sustee out of pot. If it's clogged or blocked with dirt, give it a clean first (follow the directions above). There are 3 components inside your Sustee, the core, a blue sheet and straw. It's not likely - but still possible - that the straw could get left behind inside the housing. If this happens, remove it with a pair of tweezers.

Remove the top and bottom screw caps. Pull out the old core. Insert the new refill core. Put the caps back on and off you go. 

When changing the core, take the new core out right before you need it. If you do it too early and it discolours, it won't impact it's ability to read water or how long it lasts.
