Woke up on Sunday to find the floor near the W.C all wet!
Turns out that water was overflowing out of the “overflow pipe” inside the WC because the float-valve mechanism to stop the water flow once it had filled was not working (some crack in the plastic casing and also, washer did not look good). So, time to apply my plumbing skills again …
First, get and install the replacement part:
However, things did not work out 100% as another leak appeared elsewhere ..
So, for one more day, we lived with this imperfect repair job and caught the water leaking using a pail. The problem was that this old flexible hose also needed replacement, but I could not loosen the join where the leak occurred as it caused some other part to turn (namely, where the stop valve joined with the water outlet coming out from the wall
And so, to do this job required a bigger spanner than what I had at home (to prevent the stop valve from turning) 😦
But thanks to my dad (who has all sorts of tools that I can borrow from, including a bigger spanner), I finally managed to get it perfectly water-tight after spending another $7 to buy a new flexible hose and installing it!!
One thing for improvement though is how to make the flexible hose look nice instead of all twisted like above?? But will live with it for now … it can be quite “dangerous” to try and make adjustments as the parts of the piping concealed in the wall may start to leak if it is turned “accidentally”. Those doing small plumbing repair jobs at home must remember:
1) must hold on to the parts that can turn, but should not be turning, as you try to loosen or tighten some other joint
2) to use white tape for a good water seal, the direction of winding the white tape on the screw threaded part must be correct for it to be effective (basically, it must follow the direction that the nut will turn as it is being tightened).
