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.

weikee..tx for the good advise!

any pictures of how these elbows should look like?

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.

Quite true. Avoid having those pvc threaded fittings. They are bound to give you problem in years to come.



Brass fittings



Copper fittings


Stainless steel elbow

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.

Good tip! But too late for me. Wish me luck!

Phew, luckily my contractor already has intention of using stainless steel elbow like this.

Good reminder for me ! My current place plumber installed bidet outlet horizontally, said if twist sum more kenot guarantee the thing wil come loose

rmb to install a water pump as soon as the piping is ready. If there is any leak, ur plumber is responsible to rectify it. If they finished their work and left, it would b hard to get them back to fix it.

just curious then what about the piping ?

use PB mix with copper/ss elbow ? or use copper piping all the way ?

How to check for leak?

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.

seldom see ppl use PVC pipe with metal fittings..

found out that conex push-fit fittings (http://www.ibpconex.co.uk/viewRange.php?id=23)

can be used to connect to PB/PEX and the copper/ss pipes.. not sure abt PVC though...

the fittings won't be cheap...

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

For Grundfos Ch-PC pumps like weikee's 1, just turn off all the tap fittings and if the pump operates, it means somewhere is leaking.

For UNI E and PT pump (with a tank) like the one u bought, u nd to look at the gauge at the pump. If u c the pressure drops while all the taps are closed that means u have a leak.

ask your plumber to carry out pressure test, charge your piping system with 2.5x of your normal working pressure normally pressure pump work @ 40psi thus the testing pressure will be 100psi
