Keep water in your drainage traps

Voice Over: To maintain a clean environment, drainage traps should be filled with enough water and disinfected regularly.
Every week, pour half a litre of water into each floor drain. Then, pour a teaspoon of 1:99 diluted household bleach solution into the drain outlets. Thirty minutes later, pour another half a litre of water into the floor drains.
Don't alter drainage traps and pipes.
Make sure drains and pipes don't leak and aren't blocked.
Repair any defect in the trap immediately using a qualified contractor.
