Well, long story short, my spa pump, a Sta-Rite dura-glas 1.5HP, has started leaking from around the seal where the pump housing splits in half under the band clamp. I've purchased the seal kit with the mechanical seal and the o-rings. It all looks pretty strightforeward. Can you rebuild these things in place, or do you need to remove the plumbing from the pump? The way the pump is plumbed in, it seems to look like a big pain to get it out BTW, the pump still works fine, and it only leaks when it's off, and when you start it, a bunch of water shoots out.
