I'm using a 1" PVC pipe and I used a reducer to connect to the bubbler. I have the Florflex bubblers but I use TOP 12 Outlet Dripper Manifold by DIG because it has the ability to connect 12 sites versus 8. It's a lot cheaper too!
Buy top 12 outlet dripper manifold by dig at Drip Depot for irrigation conversion. Free shipping and fast delivery for all your irrigation and plumbing projects.
You could use any of the decent pumps off Amazon or HFT that are of equal HP and save your self a ton of money. The floraflex bubblers require a bunch of pressure to operate correctly so make sure you get the right HP pump. The HFT pump is almost a 100 bucks cheaper
That’s only a 1/4hp so not sure if it will provide enough pressure for the flora flex bubblers or not. It probably will. I’ve tried some pretty big pond pumps on them and they won’t work so I know it needs to be a good sized pump to make them work right
