Product review (2 stars): Not what I expected!!
I went to install the valve and it was backwards compared to the one I was taking off.  This made it difficult because the connections backed up to the vent on the furnace and it was hard to rotate the nuts securely.  Not sure if I can rotate the bracket but I guess I'll have to take some time to figure it out.  Also the strainer that I bought doesn't fit inside the housing for the water tube entry.  Strainer was bought separately but I thought it would have fit into place.  I think I made a mistake to purchase this part but everyone else including Aprilaire wanted a lot more.
