40mm pipe ‘odour’ trap

[RogerS]

At our last place I installed inline ‘odour’ traps. They were rather clever and has an insert that allowed waste water to flow through but then closed preventing drain smells coming into the house.

For the life of me I can’t remember the name and I need a couple.

Just use what is called a running trap, fits into a pipe run and provides a water seal just like any other trap. I avoid the ones that use any mechanical valve, flap or such as they can block and fail.

We use these: HepVO more so when fitted on a run with an appliance that isn't regularly used and the wet type traps can dry out, they can also act as air admittance valves. Can be fitted pretty much anywhere in the line, vertically and horizontally, saves a massive about of space intrusion, and I've never had or known one to fail.

HepV0 Trap roger. Useful on things that may dry up such as condensate pipes and safety valve blow offs if having to go into a drain. They also work to admit air like a mini durgo valve.

One place the HepV0 Trap is useful is on sinks where you have limited access and don't want to see the plastic trap, they can sit snug within the pedestal out of sight but do need cleaning regularly as hair can block them. Never used in a horizontal axis but I believe there is a right and wrong orientation.
