All right, let's address part#1: the flow test.

So far, pHaestus despises the bucket test (and rightfully so), and proposes a manometer instead, which is very easy (heck, I've done it, in the kitchen!). I think that there are various opinions on this otherwise.

Now I don't want to start a poll for everything here... and I tend to lean towards what pHaestus proposes, because it's simple, cheap, and relatively accurate (with the right pump).

Can we drop the bucket test, as an acceptable flow test?

The way I see it, if a typical system has a flow of ~50 gph (source: OC article), then we're looking to see a 5 gallon bucket fill up in 6 minutes, and assuming that the tester is slow on the trigger, he might measure the time at plus or minus 10 seconds.

Is this 3% error unacceptable? Is the manometer going to be that much more accurate?
