I let a friend borrow my RODI filter to fill his tank rather than transporting buckets and it came back with a leak. Its on the waste line before the restrictor where it threads into the RO housing. It appears that it does not have tapered threads. Wrapping the treads with teflon tape hasn't had any impact on the leak. Does anyone know how these fittings seal? There isn't an O-ring or gasket present.
Thanks,
