Product identity

The Studor 20297 is a two-way vent trap manufactured from black plastic. It is designed for septic drain applications where venting is required. The unit includes a push-to-fit gasket that fits inside a 4-inch DWV pipe for straightforward installation. A replaceable carbon filter helps control odours at the vent point.

Interface limits

The push-to-fit gasket seals directly inside a 4-inch DWV pipe without additional fittings. The round body measures 4 7/8 inches in overall diameter and 3 1/2 inches in overall length. Overall height is 5 1/4 inches, which determines the vertical space needed. No other pipe sizes or connection types are supported by this fitting.

Capacity headroom

Rated flow capacity is 7 litres per second through the vent. The replaceable carbon filter maintains odour control until it becomes saturated, at which point it can be swapped without removing the trap. The assembly is not ligature resistant, so it is unsuitable for environments where that feature is required. It is restricted from sale in certain states, so local code compliance must be verified before purchase.

Questions about this item

Should I choose the 3-inch or 4-inch fitting for my DWV pipe?

The unit includes a push-to-fit gasket that fits inside a 4-inch DWV pipe, so select the 4-inch option for that size.

What does the 7 L/sec flow rate mean when the vent is installed?

It indicates the maximum air volume the vent can pass under test conditions, allowing the drainage system to breathe without siphoning traps.

What connection standard does the rubber gasket follow and what pipe size does it accept?

The push-to-fit gasket is designed for a universal fit inside 4-inch DWV pipe and does not reference a specific industry standard.
