You don’t necessarily need to get your pump replaced. If this is the first time your Hiblow HP80 has stopped, all you need is the repair kit to rebuild your aerator. Hiblow air pumps need to be rebuilt about every 3 to 6 years, depending on where you live. One thing to look for is red dust in the unit; this means the magnetic rod block is getting too close to the coils. This happens when the coils get weak. It is advised you get a new hiblow air pump if this has happened.
One of the first signs your septic tank aerator needs to be rebuilt if the septic tank alarms are going off. This happens due to the pressure dropping, which happens due to the aerator not working correctly. If you are unsure if you can rebuild your aerator because of how old it is, the date is printed on the barcode sticker of the pump on the back. The first four numbers are your month and year made in that order. Anything under 10 years should be able to be rebuilt. Anything over, we advise buying a new Hiblow HP80.
