Every few days when I fill the kettle for my morning cup of tea, the water comes out of the tap cloudy, sometimes very brown. It is only ever a glassful or so and it is not due to flushing mains. I'm guessing it is corrosion in the taps/spigot.
How far back in the plumbing needs to be replaced?

Sounds like it's connected to the sewer
note I'm not a plumber, I'm on $50 hr less

is it cloudy straight away? or does it come through clear initially.
If it's there immediately the problem is close to the tap, I'm assuming the other taps in the house are OK?

So the volume of water that's cloudy will indicate the length of pipe, depending on the pipe's internal diameter. If it's rusty it's probably galvanised, 1/2". Lets assume that's 10mm, (if the pipe is rusty, it will be a bit blocked, and 10mm makes calculations easy).

My maths are getting rusty so don't take this as gospel, but I make that aprox 12m per litre.

It's just the first bit. I thought pipes are copper, decent fittings are brass.

Depends how old, I'm not sure when they switched from galvo to copper, but it was a while ago.
But copper/brass doesn't rust, that's why I assumed galvo.

They can weigh the universe with that kind of thinking.
Measure the volume of clean water , then 2 pie r in reverse .
Totally makes sense. Love it

Is it a mixer , with an "Easy hooker" on it?
the hookers are renowned for rusting out particularly if there's a loop in it hanging lower than the wall outlet, corrosion in a mixer would also drain there

You using the hot or cold tap?
It could be a few things if brown including spindles all crappy, rust, sediment....
First thing I'd do is clean out aerator in outlet and work back from there.

Those guys are only braided steel externally and have black rubber lining internally. Rust can't come in contact with the water.

Thanks, Saltiest. If I get what you are saying, I should try changing the washers in the tap body.
The plumbing is probably 30-40 years old and doesn't seem to have any sort of aerator.

do you have an electric hot water system, or electric booster on a solahart??

possibly the sacrificial anodes are fizzing away to nothing and stirring things up,

Heat pump system. I think it was brown on the cold tap yesterday
Hadn't thought of that possibility

Btw plumber 31yrs.
House 40yrs old might have a section of gal nearby but mostly copper by then unless rural area. Gal will need removing.
Storage hot water units can gain sediment and heavy deposits that get stirred up once thick enough in base but this doesn't flush through for ages. Minutes usuallly.
