REQUIREMENTS OF GOOD TRAP:

1. IT SHOULD BE CAPABLE OF BEING EASILY CLEANED.

2. IT SHOULD BE EASILY FIXED WITH THE DRAIN.

3. IT SHOULD BE OF SIMPLE CONSTRUCTION.

4. IT SHOULD POSSESS SELF-CLEANSING PROPERTY.

5. THE INTERNAL AND EXTERNAL SURFACES SHOULD BE OF SMOOTH FINISH.

•Depending upon the shapes the traps are classified as:•P-Trap•Q-Trap•S-Trap

•Some other kind of traps are:•NAHNI-Trap/FLOOR-Trap•GULLY-Trap•INTERCEPTING-Trap•GREASE-Trap•BOTTLE-Trap

CLASSIFICATION OF TRAPS

Page 8: TRAPS AND ITS TYPES USED IN A  BUILDING

P Trap • This trap is used with Indian water closet. • The traps are made from cast iron or UPV sheet. • This trap also has water seal and prevents entry of foul gases to the house.

Page 9: TRAPS AND ITS TYPES USED IN A  BUILDING

S Trap• This trap is similar to P. trap and is used for fixing water closets in toilets.• The only difference between P trap and S trap is that P trap is used for outlet through the wall whereas S trap is used for outlet through the floor.

Q Trap• This trap is used in toilet under water closet.• It is almost similar to S trap and is used in upper storey other than ground floor.

• Evaporation

• Capillary action

• Momentum

• Leakage

• Wavering out

• Compression or back pressure

• Induced siphonage

• Self siphonage
