I must say that Aqua C has the best costumer service around. I emailed them about what the footprint is for an EV 120 and also telling them that I have problems with micro bubbles from my Urchin Pro. They are sending me some screening to put into my Urchin Pro output side to try to block the bubbles. The screw that you take out to clean the injector was stripped out and they sent me two new screws and two new bands for the collection cup. They are really customer friendly, I will continue to buy Aqua C products!
