Stop pouringmoney downthe drain.Literally.

Nine litres of clean, treated, already-paid-for water goes down the drain before every shower, because the water in the hot line has gone cold since the last one. Save Flow holds the valve shut until it is warm and returns the rest to a tank.

01 — The waste

Nobodysees it go.

The water between your heater and your head has been cooling since the last person showered. That is what arrives first — clean, drinkable, and on its way to the drain while you stand there with a hand under it.

The size of it

Nobody is doing anything wrong.
That is the problem.

Every Australian, every day Sydney Water puts household use at about 200 litres per person per day, and seventy per cent of it is used at home.

Down the drain before you step in A US field study of real shower events measured an average of 3.48 gallons run off while waiting for hot water. That is nine litres, per shower, before anybody is wet.

36 glasses — one shower

Glasses of drinking water. Per shower. Nine litres is thirty-six glasses. Clean, treated, already paid for, and poured away by somebody standing there waiting for it to go warm.

Per home, per year The commonly cited US figure is more than 3,650 gallons a year, per household, waiting for hot water. Just under fourteen thousand litres.

Glasses a year. One house. Then multiply it by the street, the tower, the city. None of it shows up on a bill as waste, because nobody meters the part that never got used.

Flow rate and waiting time from Champion Corporation's own research, conducted by a University of Sydney team under the Practera program: 7.5–9 L/min at roughly one minute to temperature. The figures here take the top of that range. Supporting data: Sydney Water household water use, NSW EPA State of the Environment. Glass equivalents at 250 ml.

03 — The valve

Shut untilthirty-eight.

A thermostatic element sits in the flow. Below your set point it holds the seat closed and the shower simply does not run. No timer, no app, and nothing for anyone to remember to do.

04 — The return

Warm onthe first turn.

With no way forward, the cold water in the line is pushed back through a U-pipe into a storage tank. Warm rises, cold sinks, and the tank separates itself — no pump, nothing moving. The water you would have lost is still in the building.

05 — The case

One shower is a rounding error.

A house saves a bathtub a week and nobody notices. The same device on a hotel floor, a gym, a barracks or an apartment tower repeats that saving at every outlet, every morning, without anyone changing what they do. That is where this stops being a gadget.

ResidentialRetrofit, one outlet at a time

Multi-dwellingSpecified at build, hundreds of outlets

CommercialHotels, gyms, aged care, defence

Move the slider above to your own building. The arithmetic does not change — only the number of outlets does.

The mechanism

Four moves,
nothing spinning

The valve holds

Below temperature the seat stays closed and nothing reaches the head.

The cold water turns around

With no way forward it is pushed back through a U-pipe into the tank.

The tank separates itself

Warm rises, cold sinks. It stratifies on its own — no pump, nothing moving.

At 38°C it opens

The shower runs, and the water that would have been lost is still in the building.

07 — The bigger number

Everybody can do their part.

Water restrictions ask people to change how they live. This asks nothing. The shower feels the same, takes the same time and costs the same to run — the only difference is that the water that used to leave unused stays in the building.

Every litre recovered is also a litre that was already treated, pumped and, in the hot line, partly heated. The saving is water and the energy that went into it.
