Really great guide to all aspects of cider making - not detailed and heavy buy easy going and insightful.

Perfect for Saniflo installation
Found a recommendation to use this AAV to install a Saniflo unit where the drop to the soil stack was significant. I was having problems with water siphoning back up to the unit after installing a new unit to existing pipework. Modified to include this unit and problem solved. The also Saniflo runs much better now it's not fighting against an existing build up of pressure. If only they would recommend this product directly!
