The guy who designed it probably never gave it a thought he just wanted to put a tap on the end of a pipe and thats what he found. Most of these taps seem to be of similar size.
You could increase the pipe size after it comes out of the tank which would give you a bigger exit hole and then fit something like a plastic 40mm gate valve. You could add a 90 degree elbow to get it to point down.

Think I would be worried about the other pipe thats hanging down. Looks like a trip to the Plumbers Merchants to see what they can come up with. The pipe that feeds the tap does not look very large. Our Laika has a 40mm pipe. Discharging tank takes minutes.

Posted on 16/06/2019 08:02 by cyberyachtI fitted a larger tap to my MH before our recent trip to Germany. Much improved draining performance. Why manufacturers fit such small bore taps is beyond me.

Yes is a real pain. Mine is 3/4 inch right from the tank outlet so cannot do much about it. I also find the smaller bore is prone to blocking up so I carry an old length of TV coax cable which I use as an unblocker, it works. When the plastic drain tap handle broke, I replaced it with a remotely controlled metal ball valve controlled from the cab. Much easier to dump over a good MSVP now even if it takes a ages to drain a full waste tank. Usual procedure is open valve and while its draining, put more fresh water in or empty the loo or do both.
