I switched to PEX tubing. It's strong but more forgiving to the bending than the PVC, also less expensive. You can use pvc stubs and u-clips for the pvc, to hold the pex at the wood frame. And if you want to connect all the PEX together at the top, you can zip tie a 1/2 inch pvc pipe at the peak.Thanks I might try this setup look very nice.
