So long story short, I built a system but it didn’t work with the 500 GPH pump I used so I just bought this big boy pictured.. lol

My question is.. how do I hook this pump up to a 1/2” pvc pipeline system ? Which fittings would I need ? It’s driving me crazy lol

That pump can only do 26ft of head. That's 11psi. Floraflex requires 15psi to 50psi to operate correctly. Basically that pump needs to be able to build enough pressure. If you hook it up it might still drip since you are close. But I think that kind of pump won't want to live at max head pressure for all its life. And I doubt the emitters will give equal amounts of water if they do manage to open.

You would remove the 1" NPT adaptor and install a 1" pvc MiP x glue adaptor and glue in a 1"x 1/2" pvc reducing bushing or 1" x 1/2" pvc bell reducer. That would get you to 1/2" pvc then you should probably install a 1/2" pvc ball valve and 1/2" pvc check valve to protect against back flow, and a 1/2" pvc union for disassembly. Im a plumber....
 
Make sure to follow the direction of flow on the check valve, there should be an arrow indicating flow direction.

well it’ll arrive from Amazon sometime today so I’ll send it back and get something else…. What about these ones ? I actually bought a diaphragm pump which will be here today, but that’s going to be used for my self draining saucers with 1/2” slip fitting bulkheads I put together myself

Thanks bro. It was driving me crazy. They don’t make 1/2” slip glue on socket to 1 1/2 -2” threaded female fitting ? Lol

Yeah they make em but might be hard to find, you can use multiple reducing fittings stacked to get you to any size you want. Happy growing ....
