I hate to tell you this but you shouldn’t use copper for a chiller in the fermenter - the low pH of the beer is going to strip copper into your beer. Switch that out for a SS coil and you’re good to go!
Is anyone having issues with the spike cleaning ball working with a March pump? Mine will turn but doesn’t spray hard enough to get much of the top wet much less clean.
How many turns do you have from full closed to full open? Do they fall back a little when you adjust them or do they stay exactly where you put them(if that makes sense)?
I originally posted that these were 3/8” barbs - they’re actually 1/2”. I’ve fixed the original post.
I used these: https://www.brewhardware.com/product_p/fflbarb12.htm
Bobby also sells a 3/8” barb version.
Also it’s 3/8” hose onto these as I originally planned to use 1/2” hose all the way...
Nicely done! Where did you get those (needle?) gas valves? Do you have more than a 1/2 turn to control a low simmer? Do they “fall back” a bit when you adjust them?
