There have been several serious reports of life snakes bites in the bathrooms. The causes of this plumbing emergency case may be: (A) Bad building plan (B) Bad Plumbing installation. Builders should make sure that block walls are properly plastered with well mixed cement up to the ceiling level.
An outer ceiling must be made of strong lasting materials that will not rotten with time to create chance for reptiles to climb into the roof. On the other hand careless plumbing installations in the house, has created loopholes for rats, lizards, frogs, toads, and even snakes to gain entrance into living apartments through the bathroom waste pipelines.
My concern of such happenings adds more, but most often when people are bitten by snakes right in their rooms, and at times such bites results to serious illness and even death.
As a professional plumber, I have gone to many homes for emergencies but many a times I come across plumbing waste pipe laid into big street drainage without any wire mesh or drain trap to cover them at all.
Recently, a house wife called me for repairs which involved big rats getting into her bathroom through waste water pipeline.
Also, another white housewife, a Russian told me how a rat ran into a toilet seat and got away through the retained water in the WC trap. Some reptiles in the search of water or cool places during hot climate, always trace water from big gutters and drain pipes into bathroom especially where we have bushes, forest and swarms.
I recommend that only qualified plumbers with years of experience should handle plumbing installations located at places mention above, materials for such jobs must be of good standard with good water seals, example are, water closets, floor drains.
All vents must be covered with stainless or plastic vent cover with tiny holes to let out air. All the baths, sinks, wash hand basin should be fixed with good resealing traps.
Never enter any dark toilet without light. Use torches where there is no electricity, where there is electricity; switch for bathroom light must be fixed before the bathroom door to enable users to light the room before entry. The above suggestions will help to prevent unnecessary plumbing emergencies in bathrooms.
