I have a very small drip coming from the outside of the return fitting. See photo below. It drips about once every 3 seconds or so. Seems to be coming from the white threaded area. It's tightened pretty good it, but needless to say we don't want to mess too much with it. Is a small drip even concerning? If so, any options? Thanks!
