I can't believe this actually fixed my little pump that I was about to throw away. There was some kind of fluff stuck under that little silicone flap on one side. Neither how it got 5here, barely used the pump. Thanks!
Thank you. Yeah I think a soft plastic would be better, or silicone if plastic wasn't able to seal against the orifice. The original flap was silicone I believe.
You're welcome. A similar fix can also work with the pumps of some water flossers. It seems that several different air pumps and water pumps use that kind of valve.
What's a good idea or suggestion if the diaphragm retaining clips are lost? I thought about chewing a piece of gum and sticking it in with that or a dot of E2000 glue...but I would rather not put these type of substances in there if someone has a better idea for something hard that will fit and hold it in. I don't think I have a small scrap of rubber right now.
I would probably just cut a piece of plastic from some plastic waste before recycling. Can be pretty thin plastic as long as it's stiff enough. The bottom of disposable plastic containers are usually thick enough to be pretty stiff. Just needs to wedge in place like the original retainers did.
i have a marina 75 that stopped working. will have to try this before running for a new one, hopefully its the problem showcased here and not a diaphragm problem.
It's not completely silent, at least mine isn't. But it is fairly quiet compared to my other pumps. I can't remember how long it ran before the valve flap broke but I believe it was a few months. The flap probably had a tear in it or some flaw from the factory which made it fail early. The rest of the pump turned out to be fine and it's been working great since the repair. Those little flexible flaps can be purchased separately but they're kind of expensive and I think the homemade flaps cut from a plastic lid work just as well. Overall I'm happy with the pump.
I would attach a clean hose to the outlet of the pump and see if I could suck air through the pump using the hose. If I couldn't suck any air through the line, then that could possibly be a blockage somewhere in the pumps air passages, because air should flow through the pump in that direction. If the air flowed okay in that direction then I would try to blow air into the pump through the outlet. The air shouldn't flow in this direction (reverse) through the pump and if it does, it could mean the valves aren't sealing properly.
My diaphragm looked fine, the magnet was fine, the inlet was clear. I was ready to throw the pump out until I found this video. Omg I couldn't believe how much gunk had been pulled into the outlet from what I thought was clean air! 😮🤢
Ive not had mine 24 hours and its stopped working. I think water crawled back up the pipe tube. Youre supposed to fit a blocker on the tube pipe but no one told me this so im taking it back today
Some pumps come with a little one-way check valve but some don't. They are a good form of insurance against backflow, but I rarely use them. Keeping the pump at least a couple feet above the water line has always worked for me. However, that may not always be enough precaution. Thank you for sharing your experience.
Interesting. If the rubber diaphragms are getting too hot during operation, then that may cause the rubber to harden and crack prematurely. Some chemicals or their fumes may cause rubber to harden. I'm not sure what else would cause that. Thank you for sharing the information

You're welcome. I wonder if maybe a little piece of the air filter came off and got drawn into the pump.
This is my kind of content!! Inventive, frugal, and effective! Love it! And especially thanks for the follow up portion.
Thank you
Thank you. Clear, concise and simple. You saved me the price of a new pump. I fixed the old one for free 😀👍
You're welcome. I'm glad the video was helpful. I enjoy saving money and helping others to do the same.
Cool video man really easy to understand.
Thank you
Helped us fix our failing pump! Thank you!
Your welcome. Glad to help.
Thank you for sharing!
I love your videos
You're welcome. Thank you for your kind words.
soft plastic i found that it works best for the flapping motion that it continusly does, do recommend. this is a great video, thanks for making it

Thank you so much, my air pump has new life.

Awsome job man. You where born for this
Thank you
Little piece of plastic to fix your pump, zero dollars. Satisfaction of knowing you repaired it yourself and didn't have to shell out $10, priceless.
Yep. It's a special feeling when a repair goes well. And it feels even better when the parts are free.

Replacement diaphragms are available on line. They're fairly inexpensive.
Is this pump silent as claimed? How long did it run without any problem?

@@BudgetPhil Thanks 👍
just what I needed. thanks
You're welcome
So what if there's nothing missing or damaged, the machine e buzzes, but no air
I would attach a clean hose to the outlet of the pump and see if I could suck air through the pump using the hose. If I couldn't suck any air through the line, then that could possibly be a blockage somewhere in the pumps air passages, because air should flow through the pump in that direction. If the air flowed okay in that direction then I would try to blow air into the pump through the outlet.

You're welcome
Also put locktite on the bolts and grease the rubber gasket that the pivot fits into
Yep, those additions can be helpful. Just need to make sure to use the correct type of grease and locktite. Thank you for the tips.

Very helpful
Thanks
You're welcome
Good info, thanks !
You're welcome
Every air pump I've taken apart has had a cracked diaphragm.

I think most of them have been Tetra brand. I no longer buy that brand.
Good job! Increase your stats > P r o m o s m !!!
Thank you
