Blue Diamond ET 80 Septic or Pond Linear Diaphragm Air Pump

I've been running this pump (ET-80) in my small 1/10th acre pond for 6 years now. It runs constantly in the summer. We have it sitting on a gravel base and covered by a decorative rock cover. We have never once brought the unit 'in' for the winter, yet when we plug it in at the beginning of each summer, it starts right up and begins immediately, moving a decent amount of water. Over 6 years, we haven't noticed any degradation. THIS PUMP HAS BEEN GREAT !!!We have it at about 7-8 ft depth and use a weighted air hose along with a Rootscape Bubbler. Truly excellent combo. We recently finished a larger (1 acre) pond and I'm looking to add the same pump to that pond. I'll have to do research to see if the unit can still push air properly at 15 ft depth, and with a much longer air hose... or I may have to step up to a larger pump (maybe the ET-120).If you have a pond, do yourself a favor and buy the ET-80 with the Rootscape Bubbler. Neither of the companies sponsored this review, but I'm just a truly impressed buyer/owner. 6 years is a good test!I'd be happy to respond to any Q's or comments, from Buyers or the company.

I really like the one I bought, on that note: it’s quite enough, first one lasted one year and bought rebuilt kit $58.00 (came with magnets and two replacement diaphragms) to fix it after it quit pumping air, save your money and just buy another one. You have a 50/50 chance that it will be quite again, the rebuild was not and was quite loud and failed after 2 hours. So I had to buy a 2nd new one for $200. The 2nd one I bought was quiet, so was the first one. To sum it up I wasted my time trying to fix the first one. So I actually paid $258.00.

Got this for septic tank noise level great!

Work but loud

My system is set up to run 24/7 and these motors seem to just get hot when they are coved up and running that har…The second time I replaced the pump I build a 3 sided air vent from a set of old French doors and that seemed to help cut down on the heating but I still lost the motor after a couple years may 3 years I’m not sure. This time I installed a timer letting the motor run about 45 minutes and rest for 15 minutes. The motor runs a little warm but not as hot as before. Plus I’m saving about 6 hours of run time a day. It’s been running a little over a year with this setup and I’m not having any issues.

This item was not new as described. This was a rebuilt item. Box was torn, old and couldn’t stand on its own.

same noise level as previous pump and has continuously worked for past 6 months. No complaints here.

It's so quiet I thought it had quit working. EZ install exact fit from older noisey unit that I could hear through brick. Saved 65% not purchasing from local septic dude.
