Get a section of 3/8 “IIRC” drain tubing. Attach this to the hose bib on the drain and open the drain with the tube in a jar, pail, whatever. Once it stops, loosen the filter a turn or two and break the seal/check valve and it will then begin completely draining. You are gonna get a little bit as it just is what it is. But, should not be a mess or more than just a couple ounces or so, if that. It’s really pretty simple this way and the bag has never been needed for me doing it this way. I actually bought enough hose and left them attached and tucked out of the way as someone else mentioned on front and back. Also, invest in a Fumoto drain valve for the oil plug. It’s simply wonderful Easy peasy.
