Garden taps are one way valves. Doh!!

I have a pair of these --hot & cold-- horizontal frostproof sillcocks. They're about 14" long, with a long stem onto which the washer is screwed, so the shut-off point is inside the house. They're equipped with vacuum breaks.

Never regretted adding the hot water faucet!:thumbsup:

That diagram does not necessarily indicate that the seal is opened by the tap. It simply shows a tap with a 'stem washer' that has possibly been opened by water pressure.

Anyway, I'll take your word for it that your taps have the washer fixed to the spindle. But I must admit that surprises me. I've changed plenty of washers in garden and indoor taps and I've only ever come across the 'stem' type illustrated in my previous post.

I've taken apart a lot of them (salvage the metal) and _all_ of them were solidly fixed to the shaft...of coruse they were _all_ built way back probably in teh 40s/50s
