We're looking to make a membrane storage canister for our 8"x40" H20 membrane by plugging one end and capping the other. What size PVC do I need for the 8x40 to fit? Does 8" work (leaving little space for storage solution) or do we need to go to something bigger (like 10" b/c not sure if their is a 9")?

I've not taken the actual measurements for the membrane as I haven't take then membrane out of the stainless pillar yet. I'm hoping the outside diameter (OD) of the membrane is like 7 3/4" and the ID of the PVC is 8". But would rather know before I go buy the PVC parts.

Why not just store it in the stainless pillar? I think I have read here that many do that.

It will not fit in 8" PVC I have tried. Also could not get 9". The canisters that the manufacturers sell are metric sizes.

It should fit in 8 inch pipe as long as its reg wall not heavy wall. My 4 inch membranes are stored in canisters of pvc

My 4" also store in 4" PVC. Just make sure all fittings go over the 8" and be sure to ream the 8" PVC inside at the mouth. It should go.
