Is it a homemade cfc? Not that there's a problem with that mines homemade. U just want to be sure its water tight on the different fittings. Also do u have a pump? I have read of guys using cfcs without a pump but idk how well it works. A picture would really help.
I made mine from Bobby m's design and it works awesome. I myself feel like I need a pump for my chiller but some guys don't use them that's up to u and your research on weather or not u need a pump. If u are planing on expanding then yeah get a pump u will need one later. But if u don't foresee using a pump for anything other then a cfc look into doing it without a pump. Chopps
