I decided to do a little testing myself just to see what would happen. I'm assuming that they did the test to the best of their ability. This is just the results of the first set of tests.
I started my machine and set it to single wand at 500 psi.
Then I connected the hose to the machine for 200' of vacuum and restricted it with a wand. I put the other wand in a 5 gal bucket and ran it for one minute. I used the stop watch function on my iphone which uses 10ths. I ran the test five times without turning off the machine so the psi wouldn't change and measured the results.
Test 1 mark on bucket.
Test 2 mark on bucket 1/8 inch below mark one
Test 3 mark on bucket 1/8 inch below mark two
Test 4 mark on buck same as test 2
Test 5 mark between test 2 and test 3
Each test was accurate with 10ths of a second.
Sorry I didn't have a fancy graduated bucket but I wasn't looking to measure the volume.
What this test proves to me is that you can't count on the pump to supply the same amount of water even though I didn't turn off the machine. Also, maybe because it was cooler the pump provided more water on the first test. From test 1 to test 3 it was 1/4 lower in a five gallon bucket. I didn't bother to measure the amount but it is significant.
I have an idea for a more accurate way to measure how much water is actually extracted but it has to start with the same amount coming out of the machine instead of just timing it.
I have a similar test ready when I get the time for the vacuum test.I want to check what happens when you pour a gallon in the end of different lengths and then check the recover. How much gets left in the hose for example ? Is 10 seconds long enough to clear it ? I don't have any 2.5 hose but I wonder how much water it holds after the 10 seconds.
Also when I do the vacuum test I will be weighing the carpets before and after which I think will tell more.
I consider myself a free thinker and I rarely believe something just because others are doing it. I have no agenda other then it bothers me not to know the truth. If their test results are right then it saves me money. I already have plenty of 2" hose. My testing may not convince a soul, who am I, but I'll bet I can come up with a more accurate way of testing short of a lab. I'll be convinced. I'll post my results as I get them just in case somebody else cares.
