Is there only one type of Honeywell 3 port valve?
My mate who’s a RGI diagnosed a fault on the CH system in our let property, as a faulty valve, he didn’t have one to change it, so he’s told me on the basis that I can get one and change it. Now, Tower valves, sold by Plumbase, are apparently a Honeywell copy. However all I can find on the valve is the number for the head, and that was by using a mirror to read the number on the back. The number is 40003616-003. I can get a replacement head, but would like to get a cheaper Tower valve if I can and have the option of replacing the whole lot if I need to. I understand that the Tower heads can be used with the Honeywell bodies. However, my question is, is there more than one type of 22mm 3 port valve made by Honeywell?
