I wanted to change my unions out on my Abyzz A400. Old ones were schedule 40. New ones were Lasco schedule 80. I ordered a replacement cover, I was surprised that the replacement was clear. I also had to get a couple metric to standard adapters. I ordered everything from CoralVue (I thought they were both on here, I guess not) When I dry fit everything I was super surprised at how loose all these were. I used standard PVC cement and clear primer. The leak is coming from where the adapter was glued to the cover. Should I have used heavy duty or some other type of cement? Really surprised pump of this cost has such a pooppy adapter system. I have seen pumps from China with better tolerances on their adapters. Thoughts on cement to use?
