I had to use some adapters to fit it to my system - the top fresh water connection is a 1" outside diameter (with an adapter to 3/4" inside diameter thread) and the bottom outlet is a 1/2" outside diameter thread with a Gardena (used a lot in Europe and Germany) style quick connect adapter included.
Thankfully taking it apart is really easy, takes no time at all.
Yeah lemmy is still a bit rough around the edges for me too sometimes, still better than the official reddit client though ;)
