tvx valve

Post by ezmike69 » Sat Feb 27, 2016 3:34 pm

geothermal heat pump closed loop.

friction with another tvx copper line has made a hole in the copper line leading to the bulb. I have no heat or cool.
1. will this hole evacuate the 410a from the entire cooling system or just the high pressure side.
2. there is pressure on the low pressure service port but none in high pressure port.
3. is the low pressure port the only port to take in 410a and does this fill the entire system.

From your observation in item #2 I think you have answered your #1 question. In a R-22 system you always fill using the low pressure port. I would assume the same is true for R-410 but do not kow for certain.
