Two random questions

[mike42]

Hi

Two things I've been thinking about and don't know the answer to. They are about two different things but didn't want to clutter up the forum with two threads. Anyway here they are!

1/ About stopcock vs lever valve. Why have a "stopcock" on the internal rising main? Wouldn't a full bore lever valve be easier to operate? Interestingly, the water company's external isolation valve is plastic and shuts off in about a quarter of a turn so maybe that is like a ball valve?

2/ What is the point of a half crossover. e.g. this:

I mean what are they mostly used for and is one side of it just regular copper pipe - the other end being a normal end feed fitting? Perhaps I should get one to have a play. I've used the full crossovers a few times but just don't get what these are for.

Thanks a lot to anyone giving me answers to these two!

The half cross over is handy if says it’s going into an elbow

Good to see Mr Puller live and kicking.

Not quite sure why you felt the need to come and whine about not having your question answered here though.

Yeah you're right it did sound like a whine but I didn't mean it to come out that way. Just pointing to where the answers are. I'll remove the "sadly" bit.
