I have a ten year old air pump meaning its sat ten years without use.It fired up and worked just fine and I want to use it on my undergravel filter. Is there any risks in using an old piece of equipment like this ? It pumps alott of air

The rubber diaphram may not be as plyable and may have a short life. It is paid for though so there is no reason not to use it.
You can get a cheap back up from Walmart for $10 (was $20 when I bought mine). I keep several backups but have only had one go bad.

Thanks buddy you always seem to answer my questions which is greatly appreciated. I just read in a book where a faulty air pump can release oil or some kind of residue that hangs on the waters surface that had me freaked out. I got plenty of backups but this one is an excellent bubbler
Its a dynatomic p350
PS does anyone use those air pump filters that you connect in the tubing? I know a check valve is a neccesity but I just recently noticed the filters was wondering if they are worth it

Yeah CHOMPERS,
You are on it bro. Thanks for all of the "quality" posts.
Some people attempt to talk about things they have no knowledge/experience on but you are very intelligent. I guess you have to be to belong to the "NERD HERD"

You won't have to worry about the oil in a simple diaphragm pump, but in hydraulic and peristaltic air pumps

Look like a bigger version of the airpump in the pic? If so, it's a diaphragm pump.

The air pumps that I have taken appart do not have anything like oil or such in them. They are typically a nylonish type plastic body with a rubber diaphragm that is vibrated back and forth by an armature. There is no liquid or goo involved. I can't imagine why or how one would have liquid in it.tcarswell;2589640; said:
Typically pumps or power heads intended for underwater use will be filled with oil because liquids are not compressible. If they were filled with air, tiny leaks would allow them to fill with water because of the difference in outside and inside pressure. By having it filled with oil, there is no place for the water to go. The oil will not compress so it will not allow water to enter. If oil leaks out, it is an indication of a serious leak. Water and/or air will have displaced the oil. Either way, oil out is a good indication water has gone in and the pump or power head should be removed from service or repaired.
Rock on Nerd Herd Thanks for the complements guys. If you see someone posting squirrely information, ask them to please indicate if it is from personal experience or if they are repeating stuff. Our hobby is plagued by a lot of myth and missinformation.
