The above is a link to a PDF manual for the SP0710 vari-flo valve.

I hope it's close enough to mine so I can use it for repair.

An interesting note is the part about placing the valve in the winter position. Never have done that, always used the closed position. Probably why mine is noisy or shot.

More to come - I hope.
