Joey Valve - on the job
The problem

5 things we heard from plumbers. Over and over.

12 years of feedback. Same problems. Every time.

0+Mildred Valves installed by licensed plumbers
12 yrsOf plumber feedback in the design
#1Selling shutoff valve in Australia

The batteries start beeping, so the homeowner pulls them out. Now my install does nothing.

Residential plumber

The ball valve closed, then jammed. No water back on without removing the whole thing.

Maintenance plumber

Called back just to replace four double As. Half a day gone. No charge.

Plumber, 12+ years on the tools

The battery was nearly dead, so the motor couldn't turn the ball. It just didn't work.

Emergency plumber

Half the time the unit's too bulky for the space. You're wrestling it in behind a hot water system, wishing it was half the size.

Licensed plumber

We heard it all. So we rebuilt it from the ground up.

The solution

What changes for you

Six ways Joey gives you your time back.

Fit it and forget it
Fit it and forget itThe sealed 10-year battery means no more carrying AAs, no more customer calls, and no homeowner can disable it. Your install stays protecting.
Zero delay
Zero delayMotorised valves take anywhere from 2 to 45 seconds to close with flooding occurring during that window. Joey acts instantly. One pulse. Water stops.
Avoid nuisance callbacks
Avoid nuisance callbacksNo jammed ball valves. No corroded mechanisms. 316 stainless steel and a solenoid with no moving ball means nothing to fail.
Built-in manual override
Built-in manual overrideWhen a ball valve jams shut, the water stays off until the unit is replaced. Joey can always be overridden manually. Rotate the solenoid. Water flows. Simple.
One valve for every job
One valve for every job15, 20 and 25mm. Compact design that fits in tight spaces.

What plumbers are saying

FAQ

Questions plumbers ask

10+ years. The cell is sealed and only draws current for the millisecond it takes to fire the solenoid, so there is no standby drain like a motorised valve.

No. The battery is sealed inside the housing - there are no AAs to pull out at 2am. The reset button is the only control they can reach.

Dry the tray, then press the reset button on the top of the unit. The LED returns to green. No tools, no callout.

There's a mechanical safety catch and a manual override, plus a USB-C input (5V DC, 0.5A) as backup power if it's ever needed.

15mm, 20mm and 25mm - one valve for every standard Australian pipe.

Yes. WMTS-476:2016. The mark and QR code are moulded into the back of every unit.

Yes - Joey must be installed by a licensed plumber.

Everything downstream of the feedback. Sealed 10-year battery instead of AAs, solenoid instead of a motorised ball valve, 316 stainless instead of brass, three sizes instead of one, and a smaller footprint in the tray.
