Which plumbing pipe best for residential purpose?GI(Jindal C/TATA C)alont with (

I live in rohtak. Most of the people faced leakage problem because of rust with GI pipes like Jindal & Tata. Same problem i also faced in my present house.

In most of buildings, GI pipes crossed through RCC from one side to another.

Most of the Architect recommends Kitec Pipes here to avoid rust & leakage.

Is it better than GI or best alternate for longterm than GI?

No body knows about the disadvantage of Kitec MLC pipe with Brass Connections.

Which one is suitable among them for underground/wall fittings or open installation (from shaft etc.(Half underground/Half open)).

Please suggest solution to prevent GI pipe from rust.

As you suggest in last post, GI is better which one is best among TATA C/Jindal C?

Please clear our doubt and help everyone.

Thanks for your valuable suggestions.

will like to share my experience with you all.

Pex/Al/PEx pipes are the best when it comes to plumbing.be sure that you use compression brass fittings with them . GI pipes are no longer used in the wetern countries because of the various problems faced with them like leakges.corrosion etc. 

PPR and Cpvc are gradually fading out since the quality issues and bonding of the joints has become a major issues, apart from that algae formation is there since its a single layer pipe 

that is why i would recommend PEX/AL/PEX pipes 

1. look for a food grade certification - only Astral and Sant rifeng have them 

2. go for PEX/AL/PEX and not PEX/AL/PE or PERT pipes 

worldwide only pex is used 

3. go for DZR brass fittings only

4. Go for a company which is  certified by NSF , no point going in for ISI since ISI has taken its standard from ASTM

i would rate three companies as the best ones in India - Sant- Rifeng(Rifeng is the biggest player world wide )

2. Upanor - again a very good company 

3. Vega 

kindly dont try the local ones kitec/jindal/vectus etc  since they are using very cheap material whose quality is not good . A faulty plumbing and play havoc with your house
