How to remove stuck Holman stormwater cap?

[Tony11]

Hi there

I have a rainwater tank connected to the house roof (new build) and whoever installed the Holman Stormwater Caps on the intake pipes put them on so tight I cannot get them off. We’re expecting our first rains in ages on the weekend and I’m after any tips on how to get them off when they are this over tightened. 

Tried by hand first then bought one of those strap levers to try and get some leverage. One of them shifted with that but the other one is completely stuck. So is there a knack for getting them loose without breaking them?
