  1. PLUMBING Presentation on Trap Loss

  2. Trap Loss At the end of this session you should be able to : • Explain what is meant by trap seal loss

  3. Trap Loss Why does Trap seal loss occur ? Trap seal loss occurs when the seal of the trap is lost as a result of poor practice and by not following the regulations with regard to sanitation pipework installation.

  4. Trap Loss There are three main causes of loss of trap seal: • Self siphonage • Induced siphonage • Compression Each one of these is the result of poor installation work

  5. Induced Siphonage • Caused by appliances connecting into a common waste discharge pipe. • This arrangement is not acceptable on primary ventilated stack.

  6. Self Siphonage • Most common in washbasins and steep sided appliances. • Ensuring the waste pipe is at the correct length and fall would avoid this problem

  7. Compression • Usually caused by discharging W.C. higher than the lowest waste connection. • Use large radius bend at base of stack (min 200mm) • Min 450mm between invert of the drain and lowest branch waste pipe.

  8. Trap Loss prevention Anti siphon trap

  9. Maximum pipe runs • Observe these maximum pipe lengths and you shouldn’t have a problem. • Loss of the trap seal can also pose a health hazard.

  10. Session Summary • We discussed what the causes of trap loss are. • Looked at each of the causes of trap loss. • How to rectify the problem of trap loss.
