Re: Flow through fry boxes

[Barry Cooper <bjc3 at cornell_edu>]

Lee,

Because you are replacing water you probably use a lower flow than I do. 
Even so, I also still have problems with variable flow rates, and rates 
change over time as material builds up in the valves and tends to block 
them. I find a periodic adjustment and flush to be necessary. Again, I 
recommend those little black ball valves sold by JEHMCo and others. They 
block less readily than needle valves.
