When I said the Guardian would pump about 640 GPH. I looked at the info you sent me last week. I eyeballed the chart on p. 4, and since they don't give readings at 46-48 psi and 10' lift, I interpolated between the 40 and 60 psi numbers and the 9' and 12' lift. Based on that, which yielded my estimate of 640 GPH, it would seem that the Guardian has the lowest water removal of the three (Basepump and Water Commander being higher). However, since you recommended the AYMcD product, I thought you might have had some experience with this particular model - and if there is something I should consider beyond the specified pumping capacities. I only see one AYMcD model - the other products are essentially accessories for the Guardian.
So, based purely on the numbers, and the fact that my water supply is 1 1/2", it would seem that the Water Commander would be best suited for me - I know that if my main pump fails during a heavy rain, 640 GPH won't cut it - I'm sure my main pump has twice that capacity.
But before I made the decison, I wanted to make sure I wasn't missing anything.
Thanks again. |
