What materials can be used on hot water distribution pipes

[Girl Plumber]

Hi, allow me to introduce myself.
Im on my first year of a 2 year plumbing course and loving it.
Im busy revising right now for my hot water test, and one question is saying you can use the following materials on hot water distribution ...
Copper Pipe
Galvanised Steel
and Polybutylene pipe.

Why cant one use LCS?
thanks guys

Looking forward to reading up on the interest posts on this forum - looks great.

oh and welcome to the forums

Thanks, so where can you use it? I was under the impression you could use it on cold water systems at least ... maybe Ive got the wrong end of the stick - maybe its for cold water distribution from a CWCS where you'll not be drinking that water anyway

Thanks Steveb

Hi girl plumber and welcome agree with previous posters rust! where in the east end are you from? I was born in Bethnal Green E2regards turnpin

 

[Girl Plumber]

LCS is used in central heating runs. What brought you over here? I wanna go to NZ!

 

[PlumbBobBob]

lcs you can use on heating systems mainly used in industrial situations.
you beat me to it resolute

Ah, right, thanks guys, so central heating but not perhaps normal hot water, as in for outlets (basins, taps, etc.)

It is a great place - as in very friendly and laidback socially, but very isolated physically, for example on your annual leave you're not going to get very far, flights are too expensive and long. Very expensive for goods as well. The cost of things is much higher due to importing -a pair of shoes that might cost for example 10% of your weekly salary, will cost 30% there. Its hard to get ahead.
You cant order anything online without a hullabaloo!, you have to go in physically to the shop and speak to the staff. Can be a good thing or a bad thing I guess.
A lot of people love it there, you at least dont have to put up with the relentless crowds like in London.

If you can sell a property or have money to take out there if emigrating, then you're laughing life will be 'well-good' for you out there. Some money is the key. Its not cheap out there like people seem to think, anywhere I think where the population is low its pricey.

You should visit resolute, you probably would love it. You only live once.

I might go back one day, but not for now ...

Welcome Girl Plumber, I'm a big fan of NZ one of my best mates lives in Queenstown, went to see him a couple of years ago, we went snowboarding on Coronet (concrete lol) Peak, fantastic holiday.
LCS is fine with heating and chilled circuits as it's all dosed to the max with nitrite (inhibitor) no good with hws as Turnpin and Steveb have said.
Good luck with your studies

 

[Girl Plumber]

Yeah queenstown is a gem, I must admit
I took my otherhalf there and all round the s.island and he couldnt get over how nice it was.

LCS - Low carbon steel.

It used to be called malleble iron (MI) or black iron or just steel.
It rusts therefore is only used for gas, oil or heating.

You wouldn't like to lie in a bath of orange water would you?

Galvanised steel is very rarely used on domestic in this country. It suffers from mineral build up inside the pipe which will eventually restrict the flow. Moreso on hot than cold.
Reasons it is not used.
Harder and more time consuming to install.
Shorter lifespan than copper or plastics.

Thanks Tamz - I see. So in the test it says galvanised steel but you probably wouldnt bother in the real world. Cheers
