Drainage system consists of gutters, floor traps and pipes etc. that are normally laid underground for draining out the waste water from kitchen, washrooms and from floors or any other parts of the house. Due to this, these pipes run through major part of your house. In modern construction, plumbers prefer to keep these pipes out of the interior of the house, as much as possible. That facilitates its effective cleaning without disturbing the interior of your house.

But in any case, floor traps have to be fixed at various places in order to collect the wastewater from all around the house. When something goes wrong with entire or a part of this drainage system, the bad smell starts emitting from any drain, anywhere in the house. If not fixed timely, this smell may spread all over in the house and in the worst case, the drain may be blocked. It is therefore very important to fix the problem immediately on noticing the bad smell from any drain in your house.

Here we are suggesting some very effective tips on how to fix the bad smelling drain.

Causes Of Bad Smell

There may be several reasons for the bad smell coming out of a drain. It may be a single or the combination of any of these:

  • The smooth flow of water is the lifeline of a drainage system. If for any reason, the flow of water is blocked that particular part of the system starts accumulating debris that ultimately causes the bad smell.
  • Sometimes the main pipeline that drops into the main sewerage starts smelling that ultimately comes out of any drain or floor trap in your house. Actually, this smell is coming from the main sewerage pipe.
  • Elbows and U-bends are frequently used in the drain system. Sometimes waste residues and debris starts accumulating in these bends. This may cause the bad smell in the drain.
  • The kitchen is perhaps the major culprit when it comes to the blocking of any part of the drainage system. Food wastes should normally flow away in the pipes from your kitchen without any hindrance. But it may start accumulating around the kitchen sink or in any bend or pipe in the kitchen that results in bad smell and blockage of the drainage system.
  • The laundry area is also vulnerable to accumulation of lint and debris in or around the washing area. That also causes blockage and bad smell.

Clean And Clear The Bends

Elbows, bends and especially the U-bends are always prone to get blocked with waste residues. Ensure to clean U-bends periodically. Remove the u-bend, clean it thoroughly with water and reassemble it on its original place.


Apart from it, all other bends (including the U-bends) may be cleaned regularly with water. Normally, these bends have an open end, covered with a lid. This lid can be unscrewed easily thus providing you access to the bent portion. Clean this inside of the bend with plenty of water, remove any debris from it and screw back the lid. This may be done frequently so that debris should not accumulate so much.

Clean With Chemical

Sodium Hydroxide is a powerful chemical that removes the debris and waste residues from the drains quite effectively. Use it in diluted form. Being highly toxic should be handled very carefully.
