Product details
The Pentair 51000511 is the black lid, complete with the printed position label, for the 1-1/2 inch side mount multiport valve. It is listed for the 501501 and 501601 valves.
Why lids get replaced
The lid is the part of a multiport that lives in direct sun and takes the most chemical exposure. The printed label fades until the positions cannot be told apart, and the plastic goes brittle and cracks around the fastener points. Neither problem means the valve is finished, and neither is worth guessing about when the setting is wrong and the filter is being backwashed by mistake.
Before ordering
Check the valve size. This lid is for the 1-1/2 inch side mount body. Shut the pump down and relieve pressure before you open anything on the filter.
