Pro alloy water tank

[hoyin]

I have a pro alloy water tank installed. I am sure when I bought it I ordered a pressure cap.

I only just thought about this the other day when I struggled to take off the cap.

What should a pressure cap look like? Would it make it easier to open?

I need to check my receipt.

I brought a high pressure one from Deamon Tweaks as suggested by Tux. I'll see if I can find part number.

The rubber gasket in the pressure cap sticks to the alloy flange.ive tried a thin layer of copperslip to try stop this happening.

I have one of those lever caps, I'd love to see one tested to see what the actual rating is, I'm sure it won't be 22lbs
