— before taking vacation, turn off all bidets.  Better turn off main water supply.

In fact, this type of bidets are a clear risk in terms of water pipe break.

— water usage

• 6-resident: mid-Apr to mid-Jun, we used 37.3 cubic meter per month, based on actual reading.
• 4-resident: After mid-Jun, for two months, we used 32 cubic meters per month, based on actual reading.

Typical usage in Singapore is 4 to 10 cubic meters/M/person, so our usage (8) is within range but on the high side.

— full-load machine wash is more water-efficient

— Dripping tap may contribute a lot — amount of wastage is hard to estimate.

After the plumber fixes everything, just observe the meter. Should NOT move at all.
