Yesterday I got a new Intelliflo VS pump, and asked the tech to replace my regular 5/8" garden hose spigot with a 3-way valve so I can, "vacuum to waste." Perhaps there was a mis-communication, because this is what I got,

I'm no genius, but I'm pretty sure I can't simply attach a hose to this setup, lest it be blown into my neighbor's yard.
Can anyone give advise on what I need to complete this job? Perhaps glue some 2" PVC into this reducer and clamp on one of those blue backwash hoses? (More elegant solutions welcomed!)
There is about 75'-100' between my pump and the sewer lateral.
Thanks in advance for you help,
Jeffrey
