水草情迷

I've bought a CO2 system.... and found that the water will flow back to the meter after the electrionic switch is closed....

I've bought a 止倒流器 (one-way valve) but it seem not workable... as only HK$8...

Could you please recommend one brand of such valve (that you are using and functional) for me?? where to buy and how much??

ada 果隻幾好...
$8 彈簧果隻無用架...

水草店都有得賣，老细話係工業用嘅，一定掂，大約＄7X元

大家可以到廣東道找找,我在那裏的"華信機械有限公司"買只要$47元.他們check個spec可以受到10bar

PS: 要用硬氣喉,硬氣喉可在新填地街五金店找到,大約$1/呎......平FS很多噢.........

我用過
- $6 --> 無用
- $15 鐵製的 --> 無用
- JBL --> 無用
- 水草店 --> ok 但貴 $7x
- 高度建議 --> 新填地街/廣東道
用軟喉都ok.
