  • Cost-Effective Solution for Aerobic Septic System Repair
Style: 2550GPH(160LPM)
When the air pump in our aerobic septic system failed, we sought a reliable and affordable replacement. After researching various options, we chose the AquaMiracle Linear Air Pump. While it required a minor modification to connect the check valve and an adjustment to the power cord—common steps for this type of installation—it was straightforward to set up. Once installed, the pump operated flawlessly, restoring proper aeration to our septic system. Its performance has been consistent, and it runs quietly, which is a bonus. By handling the replacement ourselves, we saved approximately $300 compared to hiring a professional. This pump has proven to be a cost-effective and efficient solution for our needs. ... show more

  • Ample air flow!
Style: 950GPH(60LPM)
Love this pump. I've attached this to go into a 1" PVC and I run several air lines from the pipe that power sponge filters, uplift powered egg catchers, etc. Pump has more than enought power to supply air for my 4 tanks and BBS hatchery. Stays very quiet and does not get warm. Excellent purchase and I would highly recommend this. ... show more

  • Best air pump, worth the price
Style: 1350GPH(85LPM)
This air pump runs quieter than any of this type I've ever heard before. It has excellent filtration for incoming air, recommends replacing the diaphragms when they wear out from use, and has the replacement parts readily available. It's got bubbles roiling out of four big air stones and could easily handle more. We've used a series of extremely loud air pumps for our Koi pond for the past decade or so, so loud they've been the first thing we hear when we step out back. They've been pretty much 'disposable', since I've been unable to find replacement parts for them, so they've been tossed out after a couple years. I got a couple of the repair kits and expect to be using this pump for a long time. ... show more

  • Durable pump.
Style: 950GPH(60LPM)
Works as advertised. We had to send it back because I chose the wrong pump, however, we could have retrofitted it and it would have still worked fine. Solidly built pump.

  • Do not buy
Style: 950GPH(60LPM)
1 year 3 months and this is the third or fourth time I have had to replace the diaphragm gaskets. The problem is the pump is sealed so it generates heat wich softens the rubber material and it tears and does not last long. The rubber diaphram must not be rated for for heat. Update 2 years of use have to replace diaphram gaskets at least two to four times a year. Don't buy spend the money now and buy a piston air pump. ... show more
