Description
Check nylon washer this washer helps prevent wear on handle.
Used on Aquaswim Midas Praher Shenton and a lot more Sand Filters.
Check for wear as the internal valve part will not lift when you push down the handle.
We did have this valve top half but no longer only parts are this handle, the gasket and nylon washers under the handle that also should be replaced with handle.
