The other week my wife surprised me with a gift that only a prepper could get excited over: a dual-flush toilet retrofit!
I'm really excited to try out this gadget, however when I read the instructions I found out that it doesn't work with the "ball and lever" floater style fill valves. I'd have to switch over my toilet first before installing it.
There are many different types of fill valves and company that makes the dual flush recommends their own which also has a water saving feature. I picked one up at Canadian Tire for around $17.
There is also a "deluxe" version for $19 that includes jets which supposedly clean the inside of your toilet tank with each flush.
Installing it was super-easy and just took around 10 minutes. The only tool I required was a wrench to remove the old fittings, the rest is done by hand.
These things are supposed to save water through a little lever valve where you can adjust how much water goes down the refill tube and into the toilet bowl.
The instructions include a simple technique to determine the proper amount of bowl water, however I decided to try the "trial and error" method. I placed the valve at half open and there is a noticeable difference in the amount of water in the bowl. As far as I can tell this hasn't affected the flush and I estimate we're saving at least a liter each flush.
I'd recommend people try give this device a try, however, one thing to keep in mind is that it isn't meant to be used with those toilet pucks that you put in the back of the tanks. The instructions don't explain why but I assume it's because the chemicals will breakdown the plastic parts.
Soon I'll get around to installing the dual-flush retrofit and I'll post the results.
Has anybody else tried these gadgets or a similar device?
