Hey guys,

Anybody knows how to shut off water in this seemingly indoor toby? The left wheel handle wouldn't turn at all. The right one turns OK both clockwise and anticlockwise. But when I close the right one fully, water supply doesn't stop. Any help would be appreciated. Thank in advance.

It looks like a tempering valve not a Toby. It is on the hot line if that's insulation wrap on it?

@aredwood will no doubt confirm, but I think that may be a pressure limiting valve, not a shutoff. It will never stop the water flow, just reduce the pressure to whatever it is feeding.

That's a combined filter and stop valve with non return.

They're usually used on a mains pressure hot water cylinder feed so maybe just isolating the hotwater?

The knob should move inwards when turned to shut off the supply.

Right hand knob should be shutoff I believe

Edit: looks like this model http://apexvalves.co.nz/control/filter-stop-non-return-3-1/

Can you turn off toby at the street and unscrew the left hand knob (filter)? I wonder if the filter is blocked, stopping the valve from operating somehow?

Yep, that is it. The right handle should definitely stop the water. Why can't you just turn the water off from the council isolating valve?

My folks place has the toby in the garage as well. It's a 5 year old place.

The council valve looks so bad I am not comfortable about touching it. Does the right handle stop the water flow into the whole house or just into the hot water cylinder?

Just into the hot water cylinder.

Clean out the street front toby until the tap is above the mud. Put gloves on if muck & spiders worry you.

Depends where it is - it may control the whole house (if it was working).

The insulation is weird, you wouldn't put this kind of valve after a hot water cylinder, and even if it was just before the hot water cylinder, why would you insulate the cold feed?

To stop it freezing?

Easy to see what supply it controls. It is not likely that the valve doesn't shut something off.

Yeah good point, normally you wouldn't need to inside the wall but I guess if it's a particularly cold climate.

I've only ever seen hot water shut offs adjacent to the cylinder, hence my suspicion that the valve is faulty
