Just installed a Redwater device - it diverts the cold water in your hot water pipes till the hot water gets to the device then fully opens the valve to deliver the hot water to your tap or shower - it depends where you locate the device in the plumbing! It is expensive, but saves you having to collect the cold water in the shower etc when free camping! I plumbed it close to the T for the wash basin and shower, and to return the water back to the tank so none is wasted.

Hey what a great jigger
Where did you get it from ?
And when you said expensive "how expensive " are we talking
Going by the YouTube stuff on it
Looks easy to install and just run one pipe back
To the tank
What a smart young fella that made it
Good post thanks Treecrest

... when the hot tap is turned on, a small amount of water will be released from the tap and will continue to trickle. This is to show the cooled water in the line is now being diverted. Once hot water reaches your Redwater Diverter it will be directed to the tap for use.
I can see a potential safety issue with this device. Imagine that someone who is unfamiliar with this setup turns on the hot water tap. The tap begins to trickle, so they then turn the tap all the way to the fully on position. Moments later there is a gush of scalding hot water.

That is the idea, turn the tap fully on.
It only operates on a pump system, ie: caravan or a gravity feed. Hardly likely to be a sudden "gush".

Spoon fed then....
Copy from previous posts.....
REDWATER DIVERTER VALVE.
They are around $175 each,
They are installed in your hot water line going to a tap or shower head. An extra water pipe is required to connect to the valve to carry the cold water back to your tank.
I have one installed in our longest hot water line, to our kitchen as we are on tank water.
Quoted from Redwater website:-
"Our Research Has shown that an average household using the Redwater Diverter system could save approximately 16,000 litres of water every year, that's approximately *9.3% of potable water used! These figures are only based on average daily usage. You could save even more than this!
To help save water, the Brisbane City Council recommend residents have 4 minute showers. If you install the Redwater Diverter system the first half of your 4 minute shower won't be cold!
To test how much you can save, wait until the hot water pipes have cooled overnight, then use a bucket to catch the Redwater at the hot tap in your kitchen and bathroom. When the hot water arrives, turn off the tap and measure how much water is in the bucket.
If you waited at your kitchen sink for 1 minute, you could save approximately 9 litres each time you use the tap!"
... when the hot tap is turned on, a small amount of water will be released from the tap and will continue to trickle. This is to show the cooled water in the line is now being diverted. Once hot water reaches your Redwater Diverter it will be directed to the tap for use.

The device is marketed for residential use, ie mains pressure systems.

Ahh yep, had another look, on mains supply the initial cold water goes to the garden, pool etc.
I still doubt scalding water will be an issue, if it is then the HWS Tempering Valve needs adjusting as it doesn't meet Aust standards.

Gday...
From a bit of research I have seen the website for this product - it seems to be good and has won a few awards.
However, it seems that each tap needs to have one of these fitted so that the cold water is diverted to wherever it is decided.
I assume that is back to the water tank in the van when using the 12v pump and not connected to mains pressure - but where does it go when the van is connected to mains pressure and therefore there is no tank for the cold water to be returned to?
Also, at $176 per unit (from the Redwater website) that works out to be a tad expensive with three taps in a van ... but that is damned expensive in a home??
Can anyone advise if I have the bull by the proverbials or is this the case?
Cheers - John

You are correct. This is why I went for the Topargee one as in my initial post.
This unit is ONLY used when on tank water and the cold water returns to the tank, or, in my case with 3 tanks from which I draw individually it returns to the pump suction pipe, after the tank selector.
I have mine fitted to the shower which is the furtherest hot water tap from the HWS that we use. It is a manual operation and there is an indicator to let the showerer know when the hot water is at the tap.
Cheers Neil

Thanks Neil ... so how does the unit, when fitted to the shower tap/s, know when the water is coming from the mains pressure when you are in a van park etc.
Is it set to return cold water to one/all of your three tanks irrespective of whether the HWS is being fed by the tanks via pump - or via mains pressure inlet.
Now that could easily overfill any/all of the tanks.
As usual I am confused.

So you just leave the 'lever/switch' untouched when on van park's main pressure water and stand and wait for the hot water as usual ... letting their cold water go down the plug hole and ... one now assumes ... out through the sullage hose to the ground etc.
I can see the advantages when away from mains pressure ... OH well, thankfully my shower and vanity are within 1 metre of the HWS so hot water is almost right there, and the kitchen sink is a bit less than 2 metres from the HWS and there is very little 'wasted' water coz when I fill the sink for dishes, the initial cold water helps to 'temper' the hot water on my cute, delicate liddle handies.
At least I have learned something from this thread.

I fitted one of these https://www.topargee.com.au/showermiser-surface-mount.html
About $80, well worth it.

When on Mains supply the unit is not used.\
