I have replaced the plastic inlet fitting on this pump three different times. No matter how tight or how loose you connect it, it seems to work fine for up to a week and then the dang thing sprouts a leak. Is there a metal fitting that would work with this pump?

There are ones available made from brass and can usually be purchased at a good plumbing store.
