hi

can anyone advise what type of pipe to use for the main pipe from the meter (must be
underground thr the garden). some says stainless steel can be corroded by chlorine, GI will rust. can I use copper (and joint fittings) instead of PVC, PE (not suitable for DIY), etc., for underground

my previous plumber used the long black plastic one (in rolls) and it keeps damage by tree
roots !

any advise

thanks

SS is the best....if u want to keep the tree.

use POLY pipes la the black one with light blue lines running through it

thats the best for underground...

reroute the pipe away from the trees la...

wah...what tree is that?

TS, just place you water pipe inside a steel pipe (slightly bigger than the water pipe itself) at the area where your trees root are located. The steel pipe will protect the water pipe inside. Paint some bitumen coating to the steel pipe for corrosion protection.

thanks people

maybe just put a short length of SS thr the garden then revert back to other cheaper pipe

but, what about the chlorine problem for SS?

SS pipes will also rust if buried in the ground. Unless you use the high grade one, which is very costly.

Put the SS pipe inside a concrete slab. Chlorine problem you mentioned, if I recall correctly, is when you have accumulated non-moving water where concentration of chlorine is higher. For mains pipe should not have this problem.
