HUGE WORD OF CAUTION
I came home to a problem today that I want to alert others of before they go spending money like I did in a product they thought was good. I bought the air pump I am using in my current skimmer about a year ago. It is the Sweetwater SL-94 from Aquatic Ecosystems. I am sure you have all heard of the place. When I was buying my pump, I had basically narrowed it down to two choices: The pump above and the Alita pump (bigger model). Price was comparable, but the thing that differentiated them was that the Alita repair kits (diaphragms that need replacing about every 12-18 months) were hard to find and most places seemed to be out of stock at the time. I could not even find how much they cost to begin with. The Sweetwater pumps had readily available repair kits at AES for what I thought was an exorbitant amount of $75. About 3 weeks ago, I needed to replace the diaphragms as one of them broke. I ordered 2 repair kits: one to use and one to keep for future needs. The pumps started to work great again until today when I found that a diaphragm was broken again. I can see after a year, but after 2-3 weeks it is simply ridiculous. I already sent an email out to the customer service manager at AES about getting another replacement sent to me, which at the very least I expect to be free. I will let everyone know how this goes as I have found this company now to be extremely difficult to deal with in the past when it came to replacement/customer service. Maybe I have been spoiled by companies with superb customer service like PA and other, but I don't think I am out of line here. I'll let you know how this turns out.
In the meantime, I would have to say that maybe looking for alternative sources of air pumps is pretty necessary. If you can find a good source of repair kits for the Alita, I would seriously consider them before the Sweetwater any day of the week.
