Like to advice homeowner who want to redo the piping or maybe add.

When you get quote, please ask them to use Stainless steel / Brass / Copper elbow threaded fitting on the wall. The advantage is when come to replacing tap or taking and removing multiple time of tap you won't lost the thread. Using PVC / uPVC elbow fitting you risk loosing the thread and need hacking to replace the entire elbow.

Don't use GI, it will rust.

This are some of the hidden cost normal home users don't know, and why some contractor can give cheaper quote.

Sorry don't have. Most of my house tap already install.

The contract should know. And before installing the tap you can see if it PVC, Brass, Stainless Steel or Copper.

That is where some value we need to give to experience contractor.

Just come to me to give you'll this advice when today the kitchenware & toiletsware boss advice me to use SS, Brass or copper for the elbow fitting. He say is very important to pay bit more to have less headache when you want to change tap in future.

Normal PVC pipe, just the termination will be SS, brass.

Zheilwane, pump already in 2 months back. Will test it out soon. Is ok lah, my contractor, and plumber so far very responsive. I paid them like 80%. They even come install the WC, mixer..

Talk about mixer... sigh some problem with the pipe on the wall got to hack and redo. Now my Mosaic need to redo a bit. He also say will pay for all the extra charges if the Tiler sifu charge.

My contractor using. Because the wall fitting are more common to have replacement of tap.
