Pipes in stud walls

[Zymurgy]

Hi, I'm back !

More plumbing queries.

I want to run 15mm pipes down through a stud wall i'm building.

Any gotchas I should be aware of, what is the preferred method of fixing within, or are they to be left floating in loose holes bored in the studs ?

Any help appreciated.

Regards,

Paul.

For vertical, fit noggins somewhat thinner than the studding, and use pipe clips to these.

For horizontal, notch the studs and reinforce, and perhaps run a steel strap over the notch, and again use pipe clips. Loose pipes might well hammer or bang.

Never do them up tight tho - use that felt sleeving between them and teh clamps - otherwise they will creak when warming up and expanding.

Great. I'm running horizontal parallel to studs, do I batten these and secure with clips (are metal or plastic better)

Can I put a block between pipes with a pipe clip on each end clamping them together resting on the ceiling where space is tight or is this a botch ?

I've had to bend the pipes into a gentle curve to get them under the floor. (It was only possible to get 2/3 floorboards up for access on both sides of a wall.

This has left the pipes slightly bent under there. Is this normal, or should I straighten them out as best as possible. Does it matter ?

Really sorry to be asking such numpty questions, but if I don't I'll never learn to do it properly and the job will forever look bodged.

Thank in advance

Paul.

Studs run vertically.

B*llocks to it then, they can stay bent ;-)

I'm tired of waiting.

They are out of sight presumably, in which case there is nothing wrong with non-straight pipes. Indeed some plumbers even bend them through 90 degrees.

I would have used plastic pipe in that situation - it is so easy to thead into difficult locations.

Ok, Thanks.

Sorry for getting impatient, The floorboards were up and I had impending visitors !!

The pipes are only in just a gentle curve, but I was worried there would be issues when the hot water pipe expanded. Would this tend to straighten a gentle curve ?

Also what's the concensus on compression fittings on hot water pipe. Are end feed or solder ring's any stronger/better/longer lasting than compression ?

The pipes are out of sight anyway, but I didn't know what sort of out of sight plumbing crimes were perpetrated by real plumbers !

Cheers & thanks again.
