I have a Lavac in my new old boat. I assume it's a "Popular". It was working so-so to not at all so I rebuilt the pump and now it works great, except that it also leaks around the base somewhere. I think the new super suction blew a seal. The people at Lavac said that it was more likely that the base is cracked. (Probably not pumped out last winter). In any case it is a small leak and I can't really tell where it is coming from. I ordered a new seal. I thought maybe I could repair the base with epoxy if it was broken, it is made of plastic. Anyway I would be interested to hear some advice from those with more experience.
