Backwash Valves

The backwash valve directs the flow of water through the filter.  There are two main types
of backwash valves.  The simplest is the push-pull valve (known as plunger valve) and the other is the multiport valve (known also as a dial valve).  Some
filters (Purex) have a bottom mounted valve, but they are less common.
