We live and learn, thats how things improve. We have all learned a lot about cold weather working this past week or so.

Now I have a question, why are most jets brass and so the water freezes in them the minute you turn it off?

Surely plastic would be the answer.

And also, why are some wc here saying that they are working in sub-zero temps when others (ie me!) are freezing at the brush head (the little pipes going to the brush jets).?

I have made some plastic jets out of 5mm straight plastic pipe joints, just melt the one end closed then heat up a panel pin and push it through the closed end.

Does it squirt at a funny angle?

[Ron Rogers]

 if you make sure the hole is straight they will work as good as any jet, i only use them in this weather because my brass ones kept freezing up once it warms up ill be back to the brass once but these will do untill then.

Funny that. Another thing I've been saying for days and no-one listens... :

I use plastic jets on Algarde silicon stalks. The actual jets are only about 6mm in length so easy to drill a 2 mm hole straight.
You can use those plastic bolts they make to attach number plates for the jet material.
I insert the jet into the end of the silicon hose, and leave them flush with the top of the bristles.
The jets are right on the glass, so no need to remove any bristles, in fact it's the bristles that keep the stalks in place.
With having jets on the glass, they don't pick up any dirt from the brush, so great for rinsing on.
