Ventilation

HT interior drainage system, ventilation

Marley pipe ventilators for the automatic ventilation of drainage pipes


When the pressure in the wastewater pipe system drops (i.e., when the toilet is flushed etc) the valve opens automatically, drawing air into the pipes.

Where the pressure in the pipes is at a normal or raised level, the valve remains closed. No bad smells!

According to the DIN EN 12056 regulations, ventilation systems no longer need to be fitted solely via the roof. This helps to avoid leaky roofs resulting from pipe outlets.
