Need help with irrigation system

Hey all. I'm trying to switch from hydro halos to a bubbler system so i can run more plants. I'm having trouble.

Some pics below. Flow setup is check valve -> pump (https://shop.hydrolocksystems.com/collections/accessories/products/hydrolock™-in-line-water-pump) -> Y filter -> poly tubing to the manifold in the tent -> Pressure gauge -> bubblers -> ball valve for flushing.

So the first time i turned it on the pvc blew apart. Then I learned I need to cement it with PVC cement. So I did that. Tried again, and this time the poly tube connecting to the manifold in the tent blew off. Also, the pressure gauge read 60psi, even tho the pump says max 45psi?

What am i doing wrong? Do i need a pressure regulator? Thanks for any help.

What are the specs on the pump? It looks like a high pressure one. Also your push on connections where your 1/2” poly connect are barely pushed onto those barbed fittings. You want them almost all the way on those fittings, if you can’t force them on heat them up with a lighter or put in hot water. Can also put small ring clamps around them. I would also consider putting a pressure regulator in-line after that pump, seams way overkill for 2 bubblers.

I actually got it working. I switched to hose threads instead of barbed since they're much more secure. Also added a 35psi regulator right before the bubblers. I'm absolutely loving the hydrolocks now. Fine, even mist. All my plants start running off within 5 secs of each other. They keep the coco so moist there's roots growing all over the top of the medium
