Review on Pawfly 7 W 254 GPH Adjustable Quiet Oxygen Aerator Pump for Commercial Use by Christine Cepeda

I have had this pump for almost exactly a year and have used it very little in that time. In the last month it started making noise so I decided to hack the case and figure out what the problem was. At first everything looked fine, the diaphragms were in decent condition BUT inside the casing where the pump works I noticed freely moving metal shavings, obviously from the factory holes that were cut for the screws because they were never finished . Just a hard, carelessly drilled hole with uneven edges and metal fragments in the most critical element of the entire device. You can also just remove the air filter because I guarantee a loose shrapnel will most likely kill your pump long before dust particles.
