Hi all, recently a pipe that is hidden behind one of my bathroom walls is leaking (can't figure out which one).

So, I engaged a plumber who came in and cut open the ceiling and placed 4 stop valves at each pipe (to find out which pipe is leaking).

In the end, it is found out that 3 pipes require replacing (2 cold water pipe, 1 hot water pipe).

The plumber quoted me the following sum for plumbing work. Is it excessive?

1) Cut open ceiling, inspection and installing 4 stop valves - RM1850

2) Hack open 2 walls, replace 2 water pipes (PPR) and 1 hot water pipe (Copper), hole patched up with cement (tiles not included) and patch up plaster ceiling - RM4750

In total, its around RM6600.

Is this too much?

KLCC area, but nevertheless I feel its really too excessive, just checking if other sifus here have experience on plumbing works pricing.

The stop valves are needed as there is some water leaking under the floor, and he's not sure which concealed pipe is leaking, so he have to install the stop valves, and test one by one.

Normally for the plumbing works mentioned above, how much is the average/reasonable price?
