Friends

Heres a question for all you salty seadog plumbers!

The communication pipe turns into the supply pipe (underground), now then, this pipe is sleeved underground near the property.

Why is this pipe sleeved?

I know the answer (now) but all on my course got it wrong on a resent test (practice).

Any answers?

Look forward to reading them.

Regards to you all.

Does the pipe go under the building? If not, surely it's for mechanical protection and protection against stress caused by ground movement.

Only sleeved if going through contaminated ground?

Thanks everyone for taking part!!!

It's, as C&G state because of ground movement.

The tutor told us, as does teh book it was for corrosion but ground movement is what C&G say.

Cheers all.

Ground movement?

?????????

As if.

What happens if this "ground movement" goes along the length of pipe where there's no movement?

Honestly!!
