Unpleasant odours and potential flooding can result in loss of customer and staff goodwill, lost productivity and revenue, and even prosecution.
These are measures that can be taken to guard against the inconvenience of a blocked or structurally defective drain:
Regularly flush basin / bath / shower / pipework with disinfectant to clear soap residue.
Keep objects such as bottles, jewellery, toys away from where they could fall into the toilet.
To remove scale build up (in hard water areas) from a shower head (reducing flow and looking unpleasant) fill a plastic bag with vinegar and tie it around the shower head - this will dissolve the mineral deposit.
Don't use your toilet as a bin. Flushing solid waste items (nappies, wipes, cotton buds, sanitary towels) down the toilet is a fast route to causing a blocked drain. Keep a waste bin in the bathroom and use that instead.
Run hot water down the drain on a regular basis (weekly) - this will help prevent drain blockages and keep the drain free flowing.
Fit strainers to the plug holes in sinks, baths and showers. This will prevent most debris from entering the drain [such as matted hair or broken soap]. Make sure you empty out the strainers when they are full.
Do not dispose of food scraps down the kitchen sink. Pull scraps out of the plug hole, don't poke through.
Never dispose of cooking fats down the drain system. As they hit cold water they will solidify
Keep drain grids free of leaves, moss and regularly wash down with hot water and disinfectant.
Check drains are free-flowing by periodically lifting drain covers
Check gutters and downpipes twice a year. Remove any debris with a trowel
