Maintaining a Sub-Surface Dam Aerator

Sub-surface dam aeration is a popular option as these types of aerators remove the need to have power in the water and feature lower maintenance requirements than their surface dam aerator counterparts. Our sub-surface dam aerators incorporate diffusers designed to resist clogging and since the motor does not reside within the water body, there is a reduced risk of damage due to debris clogging the compressor.

This does not mean, however, that you can simply set up your sub-surface dam aeration system and ignore it indefinitely. This method will lead to equipment failure, or in the best case scenario reduced performance which equals lower water quality. It is wise to think of the air compressor that powers your system as a miniature version of your car’s engine. You wouldn’t drive your car around for years without checking your oil, pumping up your tyres and taking it to the mechanic whenever it needs a major service, would you? Treat your aerator’s compressor the same way, follow the below maintenance instructions to keep things in top shape and give us a call if you’re unsure what to do or need any help.

Throughout the year

  • Ensure that the air filter is clear of build-up and has not sustained damage – Your air filter protects the compressor from dust and other debris that will try to make its way into the motor so although it may seem unimportant its maintenance is vital to the health of your aeration system. The exact check up schedule you follow will depend on your specific circumstances and how much debris is getting trapped by the air filter but we recommend having a look monthly, possibly more often if you live in a particularly dusty environment.
    Note: Cabinets and covers are available for all compressors we sell. Unless you have a pre-existing structure which can protect your pump from dust and weather events we strongly recommend purchasing the appropriate protection.
  • Check on your diffusers – Just because our diffusers are designed to be clog resistant does not mean that they are invincible. You should check regularly to ensure that there is no organic build-up over the disc or base and make sure that they have no sustained any damage.
    Due to their design there should be little to no build up on your diffusers but it is still important to check.
    How often you need to check on your diffusers will depend on specific conditions within your water body, reach out to one of our specialists if you require advice or are experiencing any issues.
  • Check on your electrical cables – Depending on the location of your power in relation to your compressor, vehicles, people and wildlife can all pose a threat to the integrity of your electrical cables. Electricity isn’t something to mess around with so if there is any damage to your cables, discard and replace them immediately. If you notice that there is damage to a fixed cord, please contact our team and we will advise as to how to rectify the situation.

Every few years

Apply a re-build kit – Air Compressors have wearing parts that need to be replaced over time in order to keep them humming away happily. By ensuring you stick to the appropriate servicing intervals you’ll keep your aeration system in top shape.
Most manufacturers will advise when their compressors require servicing or the application of a re-build but if you are unsure, or think you’ll need to be reminded, please get in touch with one of our specialists. They will be able to advise as to timing and can set you up on a free reminder plan.
