Hello Everyone, first post, first time pool owner.
I inherited a very nice pool with a Taglus Sand filter that has a Pentair Multiport Valve on top of it.
It is leaking from the seam on one side. Here are some pics.
The local pool guy came over and replaced the whole top assembly because he did not think it was the spider/diverter gasket. He was right, with the new assembly (in the pics), it STILL leaks. You can even notice that he put sealant on it which I let sit for 24 hours before turning it on again.
What's strange is that the leak gets less and less as the pump runs until at some point, it doesn't leak at all (sorta, I haven't really done a thorough investigation, but by the time I came home, it wasn't dripping).
I don't see any cracks when it was off, he suggested that maybe the bottom is slightly warped but there is no evidence of this.
Any one EVER seen this before? Help!
