I had a clear out in my garage yesterday and found an old inline sprayer, which has a yellow tip where it sucks the chemical up whereas the one i use all the time does not have one on. my question is does this mean that both are still an 8-1 ratio for chemical metering. i have always thought my new one used a lot of chemical.
Another question is there a simple way of finding out exactly how much chemical both are metering out?
thanks
