Long time lurker, first time poster.
The diverter valve in my solar line stopped working a few weeks ago. It got so gummed up it burned out the actuator. When I took the valve apart the diverter was cracked and pulling apart so I ordered this diverter.
Its a COMPOOL diverter valve. When I got the part I went to switch it out and noticed that the two parts are slightly different - the top end of the diverter that goes into the casing is shorter on this new part. I figured that would be ok but the diverter also does not push all the way into the casing by about 2mm, but its enough to keep the top of the valve from closing. See pics below.
The real question here is - what part do I buy? Ive gone through the Pentair part diagrams and cant find another part that looks like mine. There is no apparent part number on the part itself and the guy that installed the pool is no longer around. Anyone know what diverter part I need? I need to replace the one on the left in the photo below. Thanks to everyone for their help.
Photo 1: Old diverter on the left, new one on the right. Note the length of the part coming out of the top. Much shorter on the new one. Even though the photo makes it look this way the bottom part of the pieces are identical in length and size. The only difference that I can see and measure between the two parts is the length of the plastic coming out the top.
Photo 2: Old diverter installed. Note depth - this is far enough in for the top piece to screw down tightly.
Photo 3: New diverter in same position, doesnt sink into the casing quite as far, top wont close.
