Is a drop of 3 cm in my T-line per month normal? I using 1/2" tubings.
I not sure if the rate is normal. I only using cable-ties without clamps.

Also I dropped my radiator before and there is a dent although can't tell if there is a leak.

Definatly not. Make sure all your clamps are tight and that your rad isnt leaking where you dented it. its possible that you broke a braze or somthing that isnt enough to spring a big leak, but might drip occasionally.

I would leak test your system. if you have a decent amount of antifreeze in your loop, it will show up on paper towel really nicely.

Also, is your T on tight? its possible you are evaporating a bit from the T line. and of course, some tubing absorbs fluid at a certain rate.
 
The set up has been running for about 3 months, so the bubbles have cleared, but the water level still dropping, I use about 7.5 feet of clearflex tubing and hydrx. I close my t-line with a ball-valve. when I opened it up to top up yesterday there was a little negative pressure as I could hear air rushing thru.
But I don't have an UV lamp to test. But visibly I don't see any water leaking, not sure if it's slow then dries.


what should be the normal rate?
I may go get a UV lamp and also wait another month to check the level as I topped it up all the way to the top of the line easier to judge the water level drop next month.

a bit over an inch a month I would say it's ok for clearflex. Keep in mind there is evaporation thru the tubing and that 3cm(1.18 inch) of water loss in a 1/2" I.D. tube equal 6ml. I wouldn't worry about a few drop of water worth of evaporation...
 
I get about that much evaporation. We've had weird weather as of late. it jumps between super cool and wet to super dry and hot. The dry/hot has been whats caused a lot of evaporation.
