Forum Title: Venting a Laundry Tray Pump
I'm told I need to vent the Liberty 404 laundry tray pump. Two questions. First, is there any reason why I couldn't tie into existing sanitary vent. Second, how do positively ID the vent for the 4" sanitary? I'm guessing it's the 1.5 " PVC, but I'm not certain. Thanks in advance! Mike

RESPIRADERO: la unidad tiene un respiradero para dar cabida al volumen extra del agua jabonosa y permitir el drenaje completo de la unidad. APRIETE LA CONEXIÓN SÓLO CON LA MANO. NO TAPE EL RESPIRADERO. NO USE UNA MANERA RÁPIDA VENTS o VÁLVULAS DE AIRE ADMITTENCE ya que no garantizan el rendimiento accesorio adecuado. No conecte un respiradero de paso único directamente a la unidad. Siga las instrucciones de instalación del fabricante. El respiradero deberá contar con una unión que facilite su desmontaje y deberá estar conectado a la tubería de ventilación del edificio o de la casa. for engle press 2

Forgive me, but I'm not 100% certain of how to identify an existing vent. Don't they come off the primary sanitary line in the house, typically just before a toilet or sink?
