No holes in the airline, all the pumped air goes to the diffuser.
Q.6: What’s your warranty?
Our warranty is two years.It means that if our machine has any problems within 2 years, we will send you new one or free spare parts for your replacement.
Q.7: Question: How loud is this? Ok for a residential back yard or are my neighbors going to hate me?
Noise level is subjective but you'll probably want to put the pump in an enclosure of some sort to reduce its noise if you have neighbors within a radius of 70 ft or so.
The pump is not all that noisy but if it's set up to run through the night nearby neighbors would probably hear it, at least with windows up. If located in an unsheltered area outdoors you'll need to put this pump in an enclosure anyway for weather protection, which will probably cut the noise enough. You can chose our compressor system with box type , the noise can reduce 30% .
Q.8: Question: Is there a solar option for this Aeration pump?
Yes , you can chose our DC type compressor system .More details , please contact with our sales freely
Q.9: Question: What about using in salt water?
The compressor never needs to be exposed to the water so that's not a problem. The air line and diffuser are the only things that go into the water.
Q.10: Is the pump itself waterproof?
Not waterproof, but locating it outside is o.k.
if put in a sheltering enclosure or in a reasonably sheltered place. To install it near the pond, I used a 2-part plastic doghouse with screening over the door and ventilation openings—mainly to keep bugs out—that also keeps rain and snow off the pump and this set
Q.11.Is the tubing and diffuser weighted?
The tube is a weighted hose and will not float on the water when entering the water. The diffuser reaches a water depth of 20 meters without tipping over, and weighs 2.7kg

Yes , sure , it can be customized according to your requirements .
