This is a whole house filter. you will see on the sides the reducers used to make the connections. The one on the right is how you should do it. it is just one piece with a quick connect but lowes only had one so I had to make one from two pieces. I am not sure of the exact reduction but if you go there just grab 2 garden hose quick connects and open the box and start trying reducers until you get the size you need. I also used plumbers tape/teflon tape when I went to tighten it up. I use this to fill up my buckets as well as wash the car and water sheeting it before using a leaf blower to dry. hope it helps.
