laying qualpex underground in muck

Is it ok to lay qualpex piping directly in muck together with brass compression fittings? The reason being I want to extend a hosepipe connection to the other end of the garden for occasional use?

It should be fine, Black polythene is more suited to outdoor use though.

It will be fine loads do it all the time. Its not regulation though but will be fine. To play it safe just fit an isolation valve just after where it connects to the house then come winter open the tap and close the isolation valve. This will stop water in the line freezing and causing the line to bust out doors. If your using pex keep the joints to a min as this is usually where the lines bust. Buy the pex in lengths and not off cuts from a roll as the lengths are easier to use. As a final note you can wrap the pipe in insulation just to keep it clean but make sure you empty the line every winter....

If he puts it a foot underground (say) will that not make it a lot less likely to freeze, at least along the underground part?

As it happens, we have an extension to the cold water system which runs outside the house, underground. It's in qual-pex. Haven't had a freezing problem with it (although maybe we just haven't had a cold enough winter yet). I'm sure it's not perfect, but it works fine.
