I have the switech 6000 mounted on my cpu with the included metal worm clamp and when I installed it I tightened the clamp real well, but I kept getting leaks so I kept tightening. The pump has been running for about 6 hours now and I haven't seen any leaks in the cpu block. What I'm wondering is is the clamp on tight enough now or should I give it a couple extra turns just in case? If I do tighten the clamp more could I be risking damage to the hose or the block? I have tygon 3/8 tubing with the perforated worm clamps that come with the swifty block.
